Harvest continues to roll along. Some are done and others are about half done. Wheat planting is in full force. Some issues getting N containing P fertilizers like DAP since the river is so low has cause concern. Lots of lime and fall fertilizer going down but little fall tillage yet.

Yield reports are still variable across the region. That being said we are seeing what a timely rain does to yields in some areas. Even thought the amounts of rain were not “high”, a timely rain of a few tenths seems to be making quite a bit of difference in yields. 100-150 bu yield swings where those few tenths fell on corn and 20 bu on beans is not uncommon to hear.

To paint with a broad brush, most yield reports are in the 160-180 range on corn and the 45-60 range on beans. Most everyone reports a fields or fields higher and lower than these numbers.

However, I have got numerous reports of corn in the 60-80 bu range and beans in the 25-40 bu range as well.

I’ve seen one field of corn in Tazwell County with the end rows taken off. Moisture test in early planted corn in McLean County at 20%. Harvest is slow between Springfield and Jacksonville. Farmers are trying to be patient and allow field drying but it is slow. Many harvesting just enough to stay with drying capacity. Yields 10-30% off normal. Older farmers who have farmed through 1988 are amazed at yields on 10” of rain that mostly came in 2 storms. Input prices for 2024 look better. 2023 will be the first break even year for some younger farmers.

#Harvest23 is under way! As suspected the corn yields are coming in 5-7% less than 2022 and on par with elevator tour estimates. 225-230 at 22-26%. Soybeans have been sparse so far with only 2 known fields harvested with and average of 64.
Plant health in corn continues to fade rapidly. A good shower of rain would help even up a large number of soybean acres to cut next week.

Harvest has started across most of Southern Illinois. Yields are highly variable.

Corn yield reports running from 130 to 240. High infield variability is also reported and its “normal” to hear of 175 bu yield swings based on soil type. Higher yields are being reported in isolated spots that got timely rain with lower yields also being in isolated spots of no rain. Most report so far that they are at or near their APH on yield. I suspect to see those number drop a bit as harvest moves into the mid May planting date fields. Moisture is running 22-34% out of the field and also in the same field!

Bean yields are again highly variable with yields in the mid 40s to 70 bushel. Again high infield variability is being reported with as much as 50 bu yield swings between soil types.

The soil is to dry and hard for any soil sampling at this point.

The corn and soybean crop in northeast Champaign County is continuing to progress towards maturity. Average temperatures have started to decline, but many fields of corn and soybean are either at, or more commonly, approaching physiological maturity. Some later season soybeans are still very green across their canopy, but those fields are generally at or very near R6 (full seed). Approximately 10% of soybean fields I saw in my tour through that portion of the county were in the later stages of R7 (beginning maturity), while most were at R6 (full seed) and early R7. A similar proportion, although probably a bit lower than 10%, of corn fields appeared to be at R6 (physiological maturity/black layer) based on field checks and a windshield survey.

Woodford County, IL is currently not on the drought monitor for the week. Most of the rest of Central IL is abnormally dry.
Combines are rolling about an hour south of here. Some fields gave up on life as opposed to maturing.

Corn is at R5 (dent) and most soy is at R6 (full seed), fields that still have green tissue are benefitting from recent rainfall. Areas that experienced drought conditions after pollination and during grain fill can expect corn kernel abortion near the ear tip and smaller and lighter kernels. This would be a good year to check stalk strength among hybrids and plan field harvest order accordingly. Some encouragement to hand-pull surviving Waterhemp in fields before they produce viable seed. Last week at the Farm Progress Show Dr. Aaron Hager’s team demonstrated Waterhemp samples collected from populations that were resistant to six herbicide modes of action. This includes Group 4, the growth regulators which include 2,4-D and dicamba. It has been an uneventful insect pest year to date; however, Soybean aphids were recently collected in Northeast Illinois by the Suction Trap Network https://suctiontrapnetwork.org/ and Stink bugs are easily found in soy fields I have visited.

Here in my 3 county area (DeWitt, Macon & Piatt), soybeans are in either R7 – Beginning Maturity or R8 – Full Maturity stage. All corn fields are in the Dent or R5 stage with many fields in the R6 – Physiological Maturity. A few farmers have started to harvest mature early corn varieties. Noting grasshopper feeding damage on field edges (see photo). Areas of local fields where corn was stressed during grain fill are showing signs of stalk quality issues and lodging. It might be worth your time to check stalk quality in corn fields to prevent lodging losses.

After the recent heat, it appears that most crops have turned quickly over night. Early April planted corn is almost to black layer and early April plants soybeans are turning. Harvest will be here soon. Be sure to check corn stalk quality to know which fields to harvest first.

I wish I could take the stance “If don’t have something nice to say, don’t say anything at all.” This crop is loosing its luster quickly. Insect feeding and soybean vein necrosis virus is severely limiting the plant’s ability to finish. Compound that with abnormally dry soil conditions and it’s just a bad combination. Corn and beans are going to limp across the finish line. That checkered flag will come soon than we expect when the heat returns this weekend.

Both corn and soy crops in western Champaign County are getting closer to maturity, as leaf senescence has started in several fields in that area. Corn fields I surveyed were all at mid to late R5 (dent) stages. Yields look to be somewhat variable, with a few fields having some consistently large ears and minimal tipback, while others were more affected by the droughty conditions of the season and/or weed pressure issues and will probably result in yields slightly below an expected trendline average for the county. Several soybean fields are also starting to show leaf senescence, with most at R6 (full seed) and some fields with a few plants edging into R7 (beginning maturity).

This area has not seen rain in over two weeks and is not forecasted again until 9/6. Disease presence is still low as a result. The dry conditions were exacerbated by high temperatures (upwards of 97 degrees F) last week, which we will see again this weekend. Corn is dented (R5), and soybeans are at R6. Many corn ears exhibit tip back, likely due to dry conditions around pollination. Driving around, I have observed many fields with significant weed pressure, which hopefully serve as a reminder for increased diligence on weed control next season.

Crops in McLean and Woodford County faired better in last week’s heat than other areas. Moisture would be helpful to get through next week’s return of heat.

Crops in areas with less moisture haven’t matured as much as give up on life after the heat. Shanks have weakened, dropping ears, and ceasing grain fill. Black layers showed up in fields unexpectedly.

It was a hot one and the early planted/earlier maturity corn and soybeans are starting to turn quickly. Corn is 1/2 to 3/4 milk line depending on maturity. Thus, far grainfill seems to be just fine, but would really like some rain to finish out the season. Many have started to watch out for stalk rot to know which corn fields to harvest first. Cercospora leaf blight started to show up in soybeans.

This week, I visited fields in southwestern Vermilion County. Disease levels in both corn and soybean fields was minimal; I observed only a few isolated areas in soybean fields with foliar disease symptoms. Soybeans are mostly at R6 (full pod), but a few fields were still lagging behind closer to R5. Corn fields I visited were in early to mid-R5 (dent). Ear fill was good in most fields I check, but I did find a couple fields that are struggling, with varying degrees of tipback as well as kernels aborted later in seed fill.

Recent high day and nighttime temperatures have local farmers and crops stressed. In my immediate area in Northeast Illinois the opportunity for “Bonus fill” of kernels experienced last year appears very unlikely as the R6 (dent) corn hastens to maturity. Fields with greater water holding capacity are faring much better than lighter soils, but even those are showing some remobilization of nutrients from lower leaves in the canopy for the ear. Soy are nearing R6, having a green seed filling the pod at one of the top 4 nodes on the main stem with an open trifoliate.

Much needed sunshine returned and with it HEAT. Pod shed was seen in many fields after an overcast and fairly wet previous 10 day stretch. SDS continues to show up in many fields. Reports of white mold are starting to trickle in as well. Corn is 1/2-3/4 milk line. This heat will speed up maturity. Local elevator tours showed an estimated average of 215 bu/acre.

Here in my 3 county area (DeWitt, Macon & Piatt), soybeans for the most part are in Full Seed or R6 stage. Most all corn fields are in the Dent or R5 stage with the milk line clearly visible. Soybean Vein Necrosis Virus (SVNV) is showing up in area fields should not affect yield and is caused by juvenile soybean thrips damage earlier in the season.

Extreme heat starting today. Earlier planted corn is 1/4-1/2 milk line so I would anticipate less damage to it. Later planted corn is not dented yet, there could be damage done resulting in major tip back.

Soybeans have potential. Lots of pods, mostly 3 beans each.
Corn is very variable. You name it- it’s out there. Great ears. Short ears. Normal ears. Unpollinated ears. No ears. Tipped back ears. Next week and the high temperatures are a concern. The corn has been repeatedly stressed. Will it actually reach maturity or just up and die? Probably some of both.

I visited fields in western Champaign County this week. Soil conditions are starting to dry in the top inch or so, but there is still plenty of moisture below the surface. Disease in both corn and soybean fields appears to still be minimal. That said, I did come across a couple small pockets in two soybean fields with symptoms consistent with sudden death syndrome. Soybeans are between R5 (beginning pod) and R6 (full pod), with new growth still occurring. Corn fields I visited were in late R4 (dough) into R5 (dent). Representative ears from different fields showed variable ear sizes and degrees of tipback.

Again, sounding like a broken record, hit or miss on rainfall for areas in NE Illinois. This past week some fields received inches while others received tenths. While management decisions are dwindling this late in the growing season, we can still learn from field visits. An area in a soybean field that from the road I predicted to be SDS or BSR turned out to be White Mold. While scouting I’m also noting vines becoming more visible, most on field edges, predominantly morningglories, but also Burcucumber. The morningglories can be frustrating during harvest, but Burcucumber can wrap on the reel and bring harvest to a stop. If you find areas with significant amounts of Burcucumber you may consider a harvest aid treatment. We are almost R5 for both crops, near dent stage in our corn and at or near beginning seed in our soybean. Continued low insect and disease pressure in fields I have visited.

Soils in southwestern Champaign County are now well saturated following several rainy days since last weekend. The Midwestern Regional Climate Center estimates 2.5″ to 4″ across the county, although the true range may be slightly larger. A few corn fields in the area are still showing a good amount of goose necking from high winds earlier in the season and may present harvest challenges if not harvested before stalks loose too much of their integrity. Several corn fields also showed a fairly high level of ear to ear size variability within small areas of the field. Corn in the fields I visited were at early R4 (dough) to early R5 (dent). Soybean fields are well into R5 (beginning seed) with some fields closer to R6 (full seed). There is also some new pods starting to form following the return of soil moisture.

Crop conditions are good. Soybeans are looking better than the corn on average. Lots of tip back in the corn but there are bigger kernels than usual so the yield drop may not be as bad.

Weekend rains delivered much needed relief from severe drought stress. Locally totals ranged from 1.5” to 5.5”. These rains will allow soybeans to hold pods and begin filling the lower pods. It was especially important for corn to allow grain fill without cannibalism of the plant.

Traveled through eastern North Dakota, east central Minnesota and north central Iowa this week. Definitely started where it was the worst and drove to where it was better. North Dakota has the gray shade of death to the corn. Soybeans are ankle to shin high, not a lot of nodes to pull normal yields. Normal yields are 40-50 bushels per acre. More sunflowers around Prosper than I’ve seen in several years. East central Minnesota was greener but very uneven corn fields. Beans were about knee high and with the rain last weekend have some hope. This area went from heading towards preventative plant to planted very quickly this spring. Expecting 30-40 bushels below APH on corn. North central Iowa has had the best looking crop I’ve seen this week. Could use some rain to finish well. Expecting a good crop for corn and beans but not great.

Hit or miss on rainfall for areas in NE Illinois this past week. Enough precipitation to keep the crops going, but few if any tile lines are running. Overall disease pressure continues to be low in both corn and soy fields I have visited, including those that did not receive a fungicide treatment. To date, very low insect pressure has been found in either crop. Not surprising, I’m noting Common Smut on corn field edges damaged by deer feeding. Most of the area corn crop is currently at R4 or the dough stage. The starch in the kernel, initially a liquid, is converting to a more solid or pasty consistency. Cool sunny days are favorable for an extended R4 stage. Much of the Sb crop is at R4 or full pod.

Here in my 3 county area (DeWitt, Macon & Piatt), soybeans for the most part are in mid R5 or “Beginning Seed” stage. Corn planted in the first half of April is late R4 (Dough) or early R5 (Dent) stage. Corn planted at the end of May is R3 (Milk) stage. The past two weeks has brought above normal rainfall to this region and no longer in “Moderate Drought”. Leaf diseases are at a minimum in both corn and soybean fields.

Corn and soybeans are approaching the R5 growth stage. As I type this, we are finally getting a significant amount of rain. Dryer weather, hybrid resistance, and fungicide have kept diseases like gray leaf spot and tar spot at bay in corn. But Goss’ wilt and Northern Corn Leaf blight have just started to show up. Soybeans are loving the rain and could have potential to yield if diseases stay away. One plant was found that had stem canker.

In soybeans, some feeding by Japanese beetles was found closer to field edges, in addition to both minor and advanced spider mite damage (each in different fields). With the recent rainfall and more moderate temperatures, continued damage isn’t expected but will be monitored. In corn, some western corn rootworm beetles were found but in low numbers and with minimal damage. Slightly higher numbers were observed in continuous corn. Little to no disease pressure was observed in visited fields. Corn is at R1-R2 and soybeans are at R4-R5.

Much needed 1.25” of rain this morning. Some soybeans are being sprayed with fungicides and insecticides. Corn spraying is finished for now. Several mornings this week had fog and heavy dew. Will be watching for disease to develop in the corn.

As we slip back into an extremely dry and stressful point in the growing season, more stresses are appearing. Fungicide applications made during last weeks extremely hot stretch brought out symptoms from Triazole sensitivity. SDS is showing up on early planted soybeans in areas of stress or compaction. Corn is showing tip back post pollination in the dryers areas.

Early planted corn fields are in “dough” or R4 stage and later planted fields are in “milk” or R3 stage. Most soybean fields are in the “beginning seed” or R5 stage. In my 3 county area, the 9 straight weeks of being listed in the “moderate drought” category by the U.S. Drought Monitor has reduced our incidence of leaf diseases in corn and soybean fields. This week. a little SDS is just beginning to show up in a few soybean fields. The above SDS photo was from an area of a field with deep soil compaction.

With little rain over the past week, perhaps a few tenths over the weekend, soil conditions in most of Champaign County are on the dry side. However, most fields of both corn and soy look relatively healthy with minimal external signs of drought stress. Measurements from the local Illinois Soil and Water Survey monitoring station show plant-available soil moisture at depths of 8+ inches, and it seems that most crops in the area have been able to reach some of that deeper soil moisture. That said, signs of drought stress including stunted plants and dying lower canopy leaves can be found in compacted areas of fields as well as the few hilltops we have in the county. Tip dieback and ear size was variable in the corn fields I surveyed, and most were in the late R3 (milk) growth stage moving into early R4 (dough). Soybeans were generally around R5 (beginning seed).

Scouting corn this week I’m starting to find some leaf disease, mostly lower in the canopy. To date I have yet to find Tar spot in fields I have visited but am aware it has been confirmed in Indiana Counties east of NE Illinois. Predicting what if any yield drag may arise from our dry June should be easier to determine as we progress through the reproductive stages. An interesting comparison of ear size collected from two different fields. The larger ear was collected from a heavier soil with greater water holding capacity. The second smaller ear was collected nearby growing in a lighter sandier soil on a knoll in the field.

It’s hot! Temperatures exceeding 90 degrees for consecutive days in NE Illinois. Despite the ambient temperature both corn and soy fields are holding up well, but additional rainfall would be welcome. Most corn fields are at or near R3, the milk stage. Some ears have visible aborted kernels at the ear tip. There has been minimal to no leaf disease in corn fields that I have visited, but plan on staying diligent and listening to local reports and regional reporting resources including the Corn ipmPIPE for Tar Spot https://corn.ipmpipe.org/tarspot/ to be aware of areas where crop disease has been detected. The soy crop has responded to recent rains with increases in vegetative growth and most fields are at or near R3 or Beginning pod. When scouting fields, it is still not too late to look for symptomology of herbicide damage in fields.

I’ve received several reports of corn rootworms breaking through pyramided Bt traits over the last couple of weeks. Most of these are in the usual areas north of I-80, but I was able to collect a population from Sangamon County last week and had reports from Putnam and Bureau. Continuous corn is virtually always the culprit in these cases. We are always looking for both western and northern corn rootworm populations to bioassay; if you have large numbers of adults and wouldn’t mind us coming out to collect them, please don’t hesitate to contact me.

With my area still listed as being in “Moderate Drought”, crops are still looking good. Most soybean fields are in the “full pod” or R4 stage. I surveyed 50 consecutive soybean fields on my drive and 13 (26%) of those fields had weed escapes present across the field and volunteer corn was not considered a weed escape. This is another effect of this year’s dry spring weather on the effectiveness of residual and post-emergent herbicides. Most corn fields are in the late “milk” or R3 stage or beginning “dough” or R4 stage. There is some tipback on the corn ears present. Very little leaf disease is showing up in area crop fields, which is common in a drought.

It was a good sign to see that the corn canopy was collecting as much sunlight as possible with little sunlight hitting the ground. We can’t complain, but would love more rain for corn grainfill. The insecticide application eliminated Japanese beetles and most disease. If you visit field edges where fungicide coverage was a scarce, you will find tar spot on lower leaf and gray leaf spot moving up the plant. Soybeans are hanging in there with no more insect pressure thanks to a recent insecticide application. Septoria brown spot is in the lower canopy.

Crop is moving along. The high temperature next week are going to be tough with no moisture in the forecast. Corn stalks have moved the potassium from the lower nodes towards the ears, weakening stalks.

This week, I visited fields in central Champaign County. With much of the recently forecasted rain missing the area, soils are starting to dry up again. Digging down in a few field, there is still some moisture present a few inches below the surface, but that too is starting to dry. Plants do not looked stress at this point in time, but that could change quickly with a warm week ahead of us an minimal chances for rain in the current forecast. The vast majority of corn fields I visited had finished pollination, and were generally at blister (R2) or milk (R3) stages. Soybeans were generally at beginning pod (R3) to full pod (R4). Weed control was variable, with most pressure coming from waterhemp, and a few morning glories here and there. From the road, many soybean fields still look rather clean, but waterhemp pushing through the canopy is also starting to become a more common sight in the area.

Nice weather for corn pollination. Still need consistent rain showers of .75-1.5” per week to maintain yield potential. Soybeans are R2-R3.
Insect pressure is moderate.

Wheat harvest has mostly wrapped up in NE Illinois. This week fungicide applications started in earnest, I observed fields sprayed by plane, helicopter, ground rigs and a drone! Many growers simply include a fungicide application in their management plan; however, we still encourage scouting to determine disease pressure before committing to a fungicide application. Being aware of requirements and favorable conditions for certain diseases. Examples include Northern Corn Leaf Blight and Tar Spot, both require extended periods of leaf wetness (6 – 7 Hours) for establishment. With recent rainfall many have noted early morning mist settling over some fields, facilitating the leaf wetness requirement. For those still considering an application, the Fungicide Efficacy Guides (from Land Grant Universities) have been updated for 2023 and can be accessed at https://cropprotectionnetwork.org/news/fungicide-efficacy-guides-updated-for-2023
Will the dry weather in June and resulting shorter corn plants have an effect on final yield? One of the things I have noted scouting some corn fields is the amount of light reaching the ground. In my experience during good growing seasons very little light reaches the ground at R1. As the picture demonstrates, that is not the case in all fields this year.

During my 40-mile crop survey across DeWitt, Macon and Piatt counties, I noticed several things. First, the very spotty nature of the recent rains with water standing in a field and a mile away it was powder dry. Second, it seems that residual weed control is not lasting long enough in some 30-inch row soybeans. I saw applicators in two fields spraying to control amaranth in 30-inch soybeans and other fields that had been sprayed in the past week. Third, the effects of the violent storms in late June that crossed the area are particularly evident in corn fields showing tattered leaves or elbowed stalks.
Soybeans for the most part are in the R3 growth stage with early planted fields approaching the R4 stage. Corn field growth stages varying from R2 (blister) to R3 (milk).

Corn pollination is complete. The cracks in the ground have me hoping for rain soon for grainfill. I unfortunately found that spot for the first time on our farm on a few lower leaves. We will continue to scout to see if the disease progresses and if the fungicide application holds. No report on our soybeans this week, but instead I headed to scout soybeans in Shelby Co.

Abigail Peterson unfortunately found red crown rot when scouting one of here cover crop side by side trials. I went there to investigate further and it is coming to light that this disease may have spread across Shelby County. We also found it in one field in Macon County.

Many corn fields are pollinating in the area. A few of the later planted fields are very uneven.
Soybeans are closing the rows in most fields. Some taller waterhemp above the canopy.
Wheat was harvested this week.

Since June 29th, our area has received about 7 inches of rain; however, we are still in a moderate drought. Crops are in the reproductive stage. Corn height in fields is all over the place.

Another week with precipitation, July has been much more favorable than June for northeast Illinois crops. Even with the rain, some no-till soy fields are noticeably lagging in growth behind tilled fields in our area, especially on lighter ground. Those scouting fields have an opportunity to evaluate their post herbicide applications. For many, these applications took place under very dry and unfavorable conditions. Post control and residual activity or lack thereof is evident in some fields. Waterhemp is pushing through the soy canopy and growing well in corn fields as well. Most corn fields are at or near the critical R1 or silk stage, most soy is at or near R2 or full flower/bloom stage. While scouting I noted my first Northern and Western corn rootworm adults in the area. Local wheat harvest has started and stopped between recent rains.

Our area is highly variable on crop conditions. Rainfall has been highly variable and many areas have just missed major rainfall events for region as a whole. Most of Monroe County has caught some rain on Wednesday of this week ranging from an inch in some places but others only a few tenths. Prior to that most except for the northern part of the county had received little appreciable rainfall over the last two weeks. Even when rains do come, a day or two later the soil is just as dry as it was before any rain; in most fields the deep soil water has already been tapped. Corn is mostly around tassel stage and many fields showing significant stress especially in the afternoon. Tassel emergence is highly variable and in some fields there is a concern with pollination. Soybeans are progressing but they too are showing stress. Double crop soybeans have come up fairly well and are holding there own. The best looking crops overall are those along the west, in the Mississippi River bottoms. Other than some very sandy fields most were planted early and have found some moisture.

Let see see how far this recent rain goes and hopefully catch a few more showers across the area.

For this week’s report, I visited fields in northeast Champaign County. Overall, crops look to be recovering well from the early drought stress. Soil moisture was close to optimal in the fields I visited. And with some moderate rain in the forecast, soil moisture is likely to remain adequate through the next couple of weeks. The majority of corn fields are in full pollination, while there were a few I spotted that are just starting to show tassels and a few others that were nearing the end of pollen shed. Soybeans have closed their canopy on most fields and are at R2-R3. I came across one small wheat field that was harvested, but there were no signs yet of an attempt at planting a double-crop soybean in that field. Weed pressure, largely waterhemp, was present in all the corn fields I visited, but was generally low to moderate. Soybean fields showed a variety of conditions; most appeared relatively clean while there were a few that had some serious issues with waterhemp and volunteer corn.

Corn is almost fully pollinated and recently had a fungicide/insecticide application. Soybeans have just reached R3 and Septoria brown spot is showing up in lower leaves. It’s almost getting dry again and we will need moisture for corn grainfill. High smoke in the air.

Most corn is in R1 with a few fields at R2 (blister) stage. R2 stage corn looks to have had good pollination take place. Soybean fields are in or approaching the R3 stage with good pod set on the stems. Noting a wide variety of defoliators in the fields but not at damaging levels. At this time, I have not seen leaf diseases of note on corn or soybeans.

I remain concerned about spider mites in areas which are under drought stress; I received a report this morning about mite problems in White County. Hopefully the rains this past week have slowed them down, but stay vigilant in areas under drought stress. Corn rootworm adult emergence should be well under way throughout the state. As most of the rootworm adults will still be in the field they emerged from, this is a good time to inspect fields to get a feel for the extent of your rootworm problem and how your traits/insecticides are performing. If you have high adult emergence, consider digging some roots to assess the extent of larval damage.

Speaking of damage, we learned how corn rootworm emergence tents hold up to an 85-mph derecho; not well, as it turns out. However, it was probably worth the damage to get some healing rains.

Much of the corn in NW IL was starting to roll and pineapple on late last week. The rain on June 24 -25 and late this week along with cooler conditions reduced this impact. Many fields of corn and soybean field seem to be behind in height and canopy closure at this point. Some of the early planted field which received timely showers during May and June look more normal. This really shows the spotty distribution of late spring showers.

Wheat fields are starting to turn. Late last week, I did notice wind damage in a couple of wheat fields between Pearl City and Freeport. The picture included shows what appeared to be straight line wind damage. Another field had more swirled and random damage.

Extremely welcome rains came across our area last week. Totals were .75-3”. Some storm damage south and along I74. Beans will likely canopy in the next 10 days. Corn is beginning to tassel, but looks extremely uneven.

This week, I took a drive into Douglas County to check out crop conditions. As is the story around much of the area, there are a lot of uneven corn fields as well as stunted soybeans still some ways from closing their canopy. In the fields I visited, soil moisture was variable. Some were relatively dry in the top inch or two, while others appeared to be at or near field capacity. Soybeans ranged from very early R1 to early R3. Most corn was tasseling or within a leaf or two of doing so. Some was in full flower with silks several inches long. Fields in full flower right now appeared to have more even growth across the field, while those that may have been planted a bit later or experienced drought stress a bit earlier ranged from V10-11 to R1 on plants within several yards of each other. Weed pressure, notable waterhemp, was also moderate to significant in areas of corn fields where corn plants were shorter.

Welcome and timely precipitation this past week in NE Illinois. Some areas had 3+ inches of rainfall but most had less. Adequate for now, but continued precipitation would be welcome for many. Some of the earliest planted or shorter season hybrids are starting to tassel. The emergence of tassels visibly illustrates the lack of uniform growth in some fields, likely due to earlier season stresses. Soybean are currently R1 nearing R2 (full flower). Japanese beetle adults can now be found leaf feeding. Recent rains have mostly halted the wheat harvest in northern Illinois. Potato leafhopper damage clearly detected in Alfalfa fields.

The recent precipitation events left the soil with high moisture levels, helping double cropping soybean fields to emerge. This particular field was planted about two weeks ago, under drought and without access irrigation, but plants are emerging with high vigor and uniform stand. With more rain on the radar, this particular field has good yield potential at this point.

Corn is tasseling in some fields. Uneven fields have a few tassels here and there. Judging the appropriate time for fungicides in the uneven fields will be an issue. In my opinion later is better than earlier. Be judicious on additives with the fungicides which can cause more issues with crop injury.
Soybeans are getting closer to closing the canopy. The recent rains will germinate some weeds. Read the label before attempting late herbicide applications.

Very scattered rain July 1-4 across the region. Reports of no rain to 6 inches in locally heavy spots. Rain was spotty as you may have got rain on this quarter section and not the next. On our own farm we had one rain event where we had 4 tenths on one field and basically 0 half mile down the road on another. Despite the rain we are far from out of the woods on drought. The moisture hasn’t meet yet on our own farm and most others across S Illinois.

Lots and lots of questions on April planted corn. Some 4 ft tall and trying to tassel, most without any silks. In some fields silks out but no tassels. We are seeing root issues in the dry soil, some of the storms root lodged the corn and it has nothing to hold onto with the dry conditions. Late May and June planted corn still has a fighting chance. Some fungicide is going on, but I am not sure why at this stage, there is no disease pressure and in some cases, we don’t really have a viable host.

Early planted soybeans have maybe 9 nodes in some fields and have never closed the rows on 15 inches. Heard the seed production guy say he has never seed blooms “on the ground” because plants are so short. Later planting and later maturity are doing better. Spider mites are showing up in many places.

2023 harvest is shaping up to be a highly variable mess. There will be fields of good/average yields next to almost complete disasters based on planting date and what cloud it was under when.

Corn pollination is taking place. Soybeans will be approaching R3 (pod set) soon. Both corn and soybeans will be at the correct growth stage for fungicide and insecticide in about a week. There appears to be a lot of waterhemp escapes. Also saw minor corn snap and lodging.

This week started with drought and wildfire smoke and ended with ponds in the field. Southern Woodford County had 2.5 inches of rain over two separate storms a few hours apart. The first storm was in the overnight hours and had small hail. The second storm was an intense downpour. We were lucky to not have damage to the crop in this area. Next week will be focused on which weeds are germinating and what we can do about it. The herbicide options are limited and may or may not control the weeds emerging. Cultivation is an option in organic or later planted beans that are not close to the rows closing. Read the herbicide label for crop growth height and stage restrictions.

Much of the corn in NW IL was starting to roll and pineapple on late last week. The rain over the weekend and cooler conditions reduced this impact through mid week. Many fields of corn and soybean field seem to be behind in height and canopy closure at this point. Some of the early planted field which received timely showers during May and June look more normal. This really shows the spotty distribution of late spring showers.

We have been dry again this week, having missed any potential rain chances that were predicted. Our temperatures have also warmed up with most days at 90 degrees or above for highs. This has really put the stress to crops especially in the afternoon. Overall, crops look fairly good considering the dry, but they are growing fairly slow. Some early planted corn in the river bottom is starting to tassel. Wheat harvest is wrapping up and all reports I have heard have had very good yields and quality. Double crop soybeans are emerging fairly well, but they along with everything else, will really be hurting if we continue to stay hot and dry.

Much-anticipated rainfall fell across much of central Illinois on Thursday, June 29, accompanied by high winds and hail in some places. More rain is forecast in coming days, and we hope this means an end to the drought of 2023. It would be better if the rain came more slowly without hail, but we won’t complain. Two inches or so of rain over the next two weeks should be enough to get corn through pollination in most fields, and to get soybean growth and yield potential back on track.
The fact that corn has stayed relatively short and plants are not as brittle as they would have been with more soil moisture should help the crop withstand windstorms. Short corn can have high yield potential, as long as canopy cover is complete by pollination, and leaves remain healthy. Lower leaves that have lost color may not come back, but nutrient uptake and color of larger leaves should get back to normal. We can expect soybean leaf area to develop rapidly, and having the plants shorter than normal with less internal shading may help pod development and retention as plants continue to flower over the coming weeks.
Rainfall should bring a quick reversal of the recent decline in crop condition ratings of both corn and soybean. Answering the question about whether yield potential has been irreversibly lowered by stress will get easier over the next few weeks as plants resume growth and canopy development. We do expect yield potential to recover well, if perhaps not fully in those fields most affected by drought up to now. That will be helped along by normal rainfall, temperatures, and sunlight in July.

The area received some much-needed rain. The ISWS weather stations in Bondville and Champaign recorded 1.12″ and 0.85″, respectively. On my drive back from a field day in Christian County (after riding out the storm in Pana) the storm damage appeared to be isolated largely to toppled trees and fallen limbs. While there was generally an eastward lean to most of the corn fields, I did not see any greensnap or large areas of flattened corn, at least on the field margins. The images below, taken between Villa Grove and Philo in Champaign County, are from a corn field with the most severe wind damage I found. Some of the corn is on the ground, but most plants looked to still be well-rooted and will likely stand back up over the next several days, albeit a bit “goose-necked”. Soybean fields looked unharmed and and still generally in the R2 phase. But they will likely put on quite a bit of growth and start setting some pods in the next couple weeks with more adequate moisture now available.

Some fortunate NE farms received up to an inch of rain this past week. The rainfall helped our soy crop initiate new trifoliates, improving field aesthetics by hiding leaves present when post-herbicides were applied, giving some fields a “dinged” appearance. While recent rainfall was welcomed, signs of a very dry early vegetative season, and drought conditions, persist. Corn and soy are smaller than normally expected as we near July in our region. The competition for early season soil moisture is evident in corn fields having trees on their perimeter. Wheat harvest has yet to start in northern Illinois.

Despite the drier conditions, the soybean crop is progressing and reaching reproductive stages in this area of the state. In my last report, I visited a field with known root-knot nematode pressure, so this week, I decided to check a location with a history of elevated SCN populations. That field had numerous fully developed SCN females (cysts) and foliar symptoms. We may see more SCN foliar this season compared to other years due to the widespread drought.

I will leave some SCN scouting recommendations below. Please visit The SCN Coalition (TheSCNCoalition.com) for detailed SCN sampling recommendations and management insights.
– Visit areas with a history of SCN pressure.
– Look for potential field symptoms (patches with yellow plants and reduced growth – Figure 1).
– Dig (don’t pull) some plants using a shovel (see video 3). Pulling plants may leave some of the females in the soil, especially with the drier-than-normal conditions.
– Inspect the roots and look for adult females. They are small but can be observed with the naked eye (Figure 2).
– Females will look from white/light yellow to brown, depending on their developmental stage and age.

We received .3 inch of rain over the weekend – it was a welcomed rain but not nearly enough to make a dent in the drought.

On a trip to Monmouth this past week I saw the beginning of some likely spider mite infestations; if the drought continues, these become increasingly likely in soybean. This is a great reason to hold off on broad spectrum insecticide applications, which don’t touch the mites but eliminate their natural enemies. (Also, a good reason not to mow your grassways if you don’t have to).

The dryness ensures. Class A’s holding on but class B’s are struggling. The silver side of leaves in soybeans can now be seen after mid-day. A sign of very dry conditions.

This afternoon, I took a drive through western Vermillion County. Like much of the state, still, conditions are very dry. There was large variability in growth stage between fields. Corn generally fell in the V6-V10 range, although some of the later planted fields are not quite there and appear to have significantly slowed growth. In general, the larger corn looked healthier with less water stress, indicating there is some plant available moisture at the deeper soil levels accessible to roots of these larger plants, but perhaps not by the corn closer to V6. Soybean fields also showed a good deal of variation in terms of overall growth (open trifoliates, nodes, branches, etc.), although most fields I stopped an walked into were showing at least some flowers, with several at R2. Although there was variation in the overall appearance of health in the soybean fields surveyed, there were flipped leaves and signs of water stress in all of them. I did come across one wheat field that looked to have good head size and minimal disease. Harvest for that field is likely just around the corner.

Conditions are very dry. We are starting to see Spider Mites and Japanese Beetles in our area.

Corn is hanging on as we are at least getting dew that runs down to the base of the plant. Wheat yield reports continue to be excellent. Both in bu/ac and test weight. Despite the dark clouds and a rainbow, no rain now in many locations for 35 days.

The extreme dry conditions are continuing to stunt plants and causing drought stress on crops across northern IL.

Corn, soybeans, and forages are stressed with growth stunted. V10 growth stage corn is barely shoulder high at its highest point. Soybeans planted in 15-inch rows at the end of April are finally closing over. Most corn is in the V7 – V10 growth stage with some at V11. Soybeans vary from V7 to R1. Wheat harvest is just beginning in this part of Illinois (DeWitt, Macon & Piatt Counties). Second cutting hay looks to yield about 50% of first cutting on the average across the the area. Pastures and roadsides are brown where grazed or mowed.

It is still very dry overall across our area. We have had a few scattered rain chances that have brought most at least some rain, however, we are at such an overall deficit, that it just doesn’t feel that it goes very far. Last weekend was the most “widespread” rainfall we have had, but still some areas got as little as 0.2” but many had 0.6” to 1” with a few getting more than that in isolated areas. The saving grace across the board has been our mild temperatures. Most corn and soybean fields look good and is growing but has some stress areas on hot afternoons. There are areas that missed rain where there was some replanting although it has been a balance as without rain replanting may not be any better than the first attempt. We are in full swing of wheat harvest. It has taken some time to get the crop dried but early reports are of good yields overall. Planters are tailing right behind harvest hoping to get double crop soybean in prior to any possible chance of rain.

Central Iowa corn looks good. Timely rains have been beneficial. Some unevenness on side hills but still a good color. Eastern Iowa has had insignificant rains. Areas of fields have given up. Soybeans are stalled out. Strip till potassium is holding better than broadcast.

Conditions are still dry as we have yet to receive measurable rainfall in the area. As POST herbicide applications are being made, caution should be heeded as to which varieties are being sprayed. Some non-Enlist soybean fields have had Enlist applications, resulting in serious damage and plant death. Soybeans are starting to flower, but plant growth has slowed.

Another week without a hint of precipitation in most of NE Illinois, soy has basically stopped growing and corn fields are struggling to canopy between rows. My thermometer is registering 99 degrees this afternoon. I truly hope to share a different story next week, there is concern on how long these crops can hang on before suffering significant yield consequences.

The lower-than-average precipitation not only slows plant growth but also intensifies symptoms caused by soil-borne pathogens (SCN, root-knot nematode, etc.). In this field, just outside Carmi, we can observe severe symptoms caused by the root-knot nematode (Meloidogyne incognita). The symptoms were limited to only a patch in the field over a sandy hill. This nematode does not cause nearly as much damage as SCN in Illinois, but we must keep an eye open for it.

This nematode prefers sandier soils and is most likely found in areas closer to the rivers. If you see patches with stunted plants, dig up some plants and look for galls (see image 2). There is nothing we can do to manage this nematode in this season, but a seed-applied nematicide can help in the future. Corn is also a host of this nematode, so crop rotation is less effective in this case.

South of I74 found momentary relief from continued drought conditions. Small pockets along Rt36 had 1.2-2” Sunday. North of 74 received no measurable rain. Crop growth is seemingly paused. Our only saving grace is cooler conditions.

Conditions change field to field depending on root establishment and moisture. Traveled through eastern Iowa this week and hills look really rough. Armyworm is taking out corn, soybeans and wheat in that area also. Iowa was also dry last year.

My area is dry, but cool nights and cloudy or hazy days are helping to keep stress on the lower end. Corn fields are in growth stage V6 to V10+ for the majority. Corn height is shorter than normal. Soybeans fields vary from V4 to R1 and are shorter then usual. Area wheat fields are looking good with leaf leaves clean and green with harvest getting close.

In Northeast Illinois fortunate farmers and farms received measurable rain, those that didn’t continue to watch their crops struggle in drought conditions. While most are familiar with a corn plants defense mechanism of leaf wrapping to lessen moisture loss, soy has defense mechanisms as well. Under moisture limited conditions or excessive temperature, soybean plants will flip over their leaves. This exposes their silvery-green underside which reflects more light. This process can reduce temperature stress for the plant until it experiences more favorable conditions. Even under stress, I noted the first flowers on Soy plants this week. While our preference is to have a stress-free growing season, stress during the vegetative stages of both corn and soy are less likely to have yield impacts when compared to the reproductive stages if conditions improve. Scouting V10 corn, I noted an insect egg mass on an upper leaf hatching nymphs. What did I find? Confirmed by Dr. Nick Seiter, University of Illinois entomologist, as Stink bugs.

Wheat harvest has started. Yield reports have been very good but moisture is inconsistent. Most who are harvesting are drying their wheat. Replanting is all but done. However most of the replanting on soybeans have the seed sitting in dry soil. There is good soil moisture in many fields below 3 inches. Low humidity is really playing havoc with the crop. Corn is uneven and ranges from lime green to dark green, in the same field and even between rows across most fields. In worked fields we are seeing floppy corn even with 2 inch planting depth due to roots having little to hold on to in the loose dry soil. With the lack of moisture crop damage is way up this year with a lot of deer and turkey damage. Reports of over 30 head of deer in some bean fields picking them clean at night. Some have replanted beans 3 times due to deer damage.

This field has now shown yellowing or K deficiency in large areas for this year and two years ago in corn. Very, dry which only enhances the K deficiency symptoms. No other fields in the area showing symptoms. No spring N was applied at or near planting. We plan to investigate further.

Rain in the forecast this past weekend got our hopes up, but Mother Nature let us down again. Rain gauge registered less than tenth of an inch. Hoping it rains soon.

3 to 8 tenths of precipitation in June so far. From 3 different rain events. Most crops are showing some stress in the afternoons Irrigations are putting on 1 to 1.5 inches per week. Dry land sand is about done in. Wheat harvest is a week away.

Very dry and slight crop stress until yesterdays rainfall. Crops are more relaxed now and I anticipate some rapid growth this week.

At this point it’s becoming a broken record of leading off with drought conditions. Plants have slowed their growth and corn is rolling. Soybeans wanted to shift gears into the rapid growth stage, but will be limited in dry areas. Carryover in soybeans continues to show up.

Corn will reach tassel in 1 to 2 weeks. Soybeans will reach R3 in 1 to 2 weeks. Japanese beetles are moving in on field edges. Post herbicide applications have taken place in soybeans.

Fingers crossed for Sunday’s predicted forecast.

I’ve started to receive a few reports of damage from early season caterpillar pests, including true armyworm, black cutworm, and variegated cutworm. Concentrate your scouting efforts on fields that border wheat, other small grains, or had a grass cover crop for armyworm, and fields that had sub-optimal winter annual weed control or a legume cover crop for the cutworm species. If you find larvae, note the sizes – larger (> 1 inch) larvae do the most damage, but are also the closest to pupating and “cycling out” of the damaging stage. Populations of larvae with mixed sizes or that include predominantly smaller larvae will be with us for longer.

Excellent soybean field under irrigation near Valmeyer (Monroe County). High yield potential and probably one of the best weed management programs I have seen this season.

Many areas in Northeastern Illinois are experiencing a level of drought conditions. Corn is wrapping in some fields during the day in response to temperatures and lack of moisture. Soybean growth has slowed and most are hoping for more favorable conditions before applying post herbicides in this crop. When applied under the dry conditions post corn herbicide conditions were less than ideal. We encourage growers to evaluate the effectiveness of the applications within 1 to 2 weeks. Wheat in the area appears to be hastening to maturity, it may be an early wheat harvest in northern Illinois.

A couple of much needed rain events late last week and early this week brought some relief to the very dry conditions we were starting to see in the region. POST herbicide as well as side-dressing applications have been ongoing this week. Some weed species spotted (mostly at field edges) include morningglory, giant ragweed, field bindweed, Canada thistle, and waterhemp. Late-planted corn is at the V6-V7 stages, and soybeans are at V2-V3.

Our area still continues to be dry. A few areas have got spot showers, but most have only left a tenth or two at most which only brings some short-term relief. Overall, crops do look fairly good for the lack of moisture, but week to week growth is slow with limited water. Crops do show some stress in the middle of sunny days especially with the fairly low humidity levels, but recover during the evening. The driest areas are still in the central part of the county only having received a 0.5″ of rain in the last two months. Wheat is rapidly drying down, I have not seen any harvest yet, but do expect to see some combines starting to roll in the next week if the weather pattern stays the same. Here’s to another week hoping for more widespread rain for all that need it the most!

Corn is showing symptoms of stress due to the high temperatures and no precipitation the last three-four weeks. Beans were planted May 19th and have emerged. The beans have received no precipitation since planting.

Fall armyworm activity in V3-4 corn no-tilled into small grain residue. Treatment threshold met, treated Monday June 5.

West Central IL and Northeast MO is dry. We are starting to see symptoms of drought. Corn is starting to roll and seeing some signs of nutrient deficiencies due to poor uptake on lighter acres. Northeast MO has several acres of soybeans laying in dry dirt not germinated.

Conditions are dry across northern Illinois depending on the spotty pop up showers. Many soybeans planted from May 9-15 were challenged in no-till fields due to dry conditions and tightening soils. The key is to ensure good seed to soil contact and keep row cleaners working well in no-till environments.

Many areas have slipped into the moderate drought classification. With 95° weather on the horizon, this will intensify very rapidly. Corn and soybeans both are showing the stress. Growers are worried about adding additional stress by post spraying. Herbicide carryover is beginning to be obvious with lack of moisture. Corn seems to passing from primary to nodal root system. Some fields have very awkward and ugly areas. Soybeans look to have started fixing nitrogen from nodules as many fields are to starting to get good color to the leaves.

The corn is not rolled, but still a bit spiked and sad looking. Soybeans look better except on the lighter soils and side hills. Not as dry as other places, but many fields around this area were planted later due to excess moisture early on in the southern part of Woodford County. Noticed a soybean field being planted on I-74 in McLean County this week also. The torrential downpours this week were scattered. Here we had 0.04 inches. Could use a rain, but the cooler nights are helping this crop to hang on.

Corn is starting to appear stressed, with K deficiency symptoms due to lack of rain. Early planted soybeans are starting to bloom. Growth of both corn and soybeans is stunted. Some bacterial blight on lower leaves is of R1.

Northeastern Illinois is turning dry. Post herbicide applications are taking place in corn fields. Despite dry conditions weed growth and diversity of species has been impressive in some fields, including robust vining weeds including Burcucumber and Morningglory. Early planted corn is at V6 and Soy at V2. I received reports of heavy Alfalfa weevil feeding and below average tonnage from the first cutting of hay in the region. A reminder, mechanical harvest is an effective cultural control of this pest. The Alfalfa weevil has one generation per year and overwinters as an adult. Mowing and harvesting the field removes the insect’s food and shelter. In addition, harvesting the crop can expose the larvae to sunlight which can be lethal. While the Alfalfa weevil window of damage is nearly over, farmers are encouraged to continue to scout for other forage pests that can cause damage in future cuttings including Potato leafhopper.

Plants are reaching R1 stage this week and beginning to display drought stress symptoms. Some farmers are already running irrigation systems in the region. High temperatures, elevated sand content, and lack of precipitation may limit plant growth in the following weeks in fields without access to irrigation

Crops are starting to suffer from lack of rainfall in many of the surrounding counties. With the exception of no precipitation, most all fields have great emergence and are off to a good start. Wheat is 10-20 days from harvest.

We should be in the middle of corn rootworm egg hatch in much of the state by the time this report is published. Continue to look out for armyworm injury in & near wheat and other dense grasses (cover crops, weeds, waterways, etc). Black cutworm larvae should be at cutting size throughout the state now, so include them in your scouting efforts, particularly in fields that had sub-optimal winter annual weed control. I have received relatively few reports of early season injury so far.

The cool, low humidity nights of late May have caused “silver leaf” to show in local corn fields. According to Purdue University, yield effects are negligible. Corn is mostly in the V5-V7 stage and soybean plants at about the same stage, V6-V7. Topsoil is dry down to 4+ inches fields in fields at the V6-V7 growth stages. Noticing along field edges increasing numbers of amaranth species becoming evident and this family of weeds tolerates hot, dry weather well.

This past week went by without any rain events in the area. With only one minor rain event having occurred the previous week, coupled with higher temperatures throughout this past week, soils are drying quickly. Some fields planted since the last rain event are experiencing uneven emergence due to the lack of moisture. Some pop up storms in the area today may offer some, but not significant, relief.

Unfortunately, like most we have not gotten any measurable rainfall over the past week, and with the temperatures starting to get into the 90s, it is really putting some stress on our crops. The latest planted crops are the most severely hit but all are showing some signs of stress. Locally, the central part of Monroe County has been hit the hardest, missing rainfall that has gone to the north and to the south. Hillsides of some corn fields are stressed and rolled up or bare with little emergence or stand. Many fields under normal conditions would be candidates to replant or at least patch in bare areas, however, with no soil moisture and no promising chances in the forecast there really isn’t any point to put more seeds out right now. From the Illinois Wheat Association field tour, the general consensus was that overall the wheat crop and yield estimates favored a very good crop in 2023. The wheat crop is turning very quickly which is being accelerated by the dry conditions.

It was a warm, dry week in Franklin County, like much of the state. With this, soils in the better drained fields or parts of fields are getting dry enough that crop growth appears to have slowed. However, with relatively good soil moisture levels in the county heading into this week, plant stress is still minimal, particularly in the lower lying areas. That may change as we head into next week with little rain in the forecast and temps still in the 90s on some days. The wheat in the area is still looking good overall, and much of it has started to senesce.

Unlike much of the rest of the state, soils in Franklin County are relatively moist. Some of the lowest lying and/or poorest drained fields are being planted this week and will likely wrap up by early next week. There are small low spots in some earlier planted fields that will likely need to be replanted, but those areas are relatively few. Corn that has emerged is generally somewhere in the V2 to V4 stage, and emerged soybeans are generally closer to V1-V2. As we move into next week, the hot and dry conditions may start to cause some crop stress on the tops of hills and/or in areas with a shallow clay or fragipan layer. But these dry conditions will also allow for timely weed control operations, as germinating waterhemp is now commonly visible and at the optimal stage for control. Wheat in the area is still looking good, and despite the dry weather in the forecast, will likely have sufficient moisture available for good seed fill.

Wireworms are being found and hurting stands in April planted corn on hills and Sandy soils in Saline Co this week. Scout fields now.

This is the same field in White County from my 05/17 report. Plants have reached V3 stage (V1-V2 last week). Great overall weed control, along with some post-herbicide application injuries (see photos). The recent precipitation has left the fields with high moisture levels, but the dry and warm forecast along with elevated sand content in this region may cause water stress soon.

Dry conditions persist. Stress from dryness is showing in compacted or root restricted areas. Replant has wrapped up in areas that received large rains 2 weeks ago.

Conditions appear very, dry with some moisture still in the ground for recent replanted areas. Irrigation was running on corn. Crops have not quite show signs of drought stress yet but are close.

Much of Northeastern Illinois has had a precipitation-free week. Soils are drying rapidly. Soy planted just before the most recent rainfall event is struggling to emerge in some fields. The soy hypocotyl cannot push through the crusted soil surface. Fields planted in this time period warrant a field scouting trip to evaluate emerged plant population. Most corn is near the V4 stage, Waterhemp has also emerged and is growing quickly in fields. Be aware of size restrictions on both crop and weeds with planned post herbicide applications. Sidedressing of corn with nitrogen and harvesting the first cutting of hay is underway in the region.

Corn is in the V6 to V2 growth stage, except for replanted areas. Soybeans are V3 to V1 growth stage. Crusting in some soybean fields is causing stand variability where planting was done just ahead of the early May heavy rains. Rotary hoeing may have paid in some of these fields. Currently farmers are side-dressing N in corn and are making post-emergence herbicide applications. The past week saw only minor amounts of rainfall across DeWitt and Macon Counties.

A rain event at the end of last week slowed planting a bit but the string of dry days that have followed this week have allowed growers to catch up. Most fields in the area have been planted. The light rain and subsequent warm weather have provided fair conditions to help crops emerge.

Primary field activities: Replant prairie pot holes, herbicide application, nitrogen side-dressing and hay making. Rapidly drying out and forecast is continuing dry weather.

Top inch of soil is dry but still moisture just below. Cool nights are helpful in conserving moisture but not great for plant growth. This next week will be challenging in many places with dry soil and incoming heat wave.

Still dry. Wednesday spotted one pop-up shower that did not even register on radar app. Primary field activities: herbicide application, nitrogen side-dressing and watching corn grow.

Welcomed sunshine provides a boost in early season crop growth! This dry period has allowed fields to be evaluated and planned for replant as well as ponding to go away.

Some soybeans are showing signs of herbicide injury. Weeds are just starting to emerge. There was some minor bean leaf beetle feeding with a few plants showing signs of Phytopthora root rot.

Some areas of southern Illinois are getting rain after rain and as a result field conditions are terrible. While many are near finished with planting other have yet to start. Some have lost patience for good soil conditions and are going ahead with planting; the result is a lot of poor stands and fields with the seed slot open or tunneling. Overall crop rating is a 5 out of 10.

Early planted corn is now at V5/V6, while later planted corn is at V3. Fields are clean for the most part. No signs of insects or disease.

This field was replanted into the original stand because most of the field was only 50,000 plants per acre after planting early, saturated soils, and then hail. Several weeds such as waterhemp and ivyleaf morning glory are coming on strong. Post herbicide will be needed soon.

Dropped the kids off at school and ventured into the adjacent soybean fields. Progress looks much better on the field on the north side of the road from last week. Coming out of their funk.
Many fields in southern Woodford County have crops up. Corn is VE and soybeans are V1-2. Some organic fields are yet to be planted as are the pumpkin fields. Crops just to the west in Tazwell County are farther along.
It’s raining again today.

Corn is coming along, beans are being planted today (May 19th.) A good rain is needed.

Spotty rains are moving through the area on Friday, but extremely low humidity and winds have continued to pull what little moisture is there out of the soil. It is concerning with little to no significant rain chances on the horizon and possible 90 Degree temperatures over the holiday weekend. Beans are VC-V3 depending on planting dates. Small pockets of replant for corn and soybeans are seen on western Champaign and Eastern Piatt counties.

This soybean field is located in White County, just south of Carmi. Field is currently at V1 stage, with some plants reaching V2

In Piatt County, the heavy rains of May 6 -8 have caused some emergence issues in fields planted ahead of those rains. Some fields have been rotary hoed and some not. Wheat fields have finished flowering and look good. Early planted crops are growing well, corn is at V4 and soybean at V2. Ponding damage is visible in poorly drained areas of fields. Only light rain has fallen in the past week.

Most of our area has finally received some rainfall over the last week, but it has been scattered and highly variable. I have had reports of a few tenths to a few inches across the county. Much of the area has gotten about 3/4 to 1″, however, there is a band through the central part of the county that has only gotten a few tenths at best and even that was scattered across multiple days. I have a corn demonstration plot planted 5/3 that after 2 weeks barely emerged and soybeans planted that same time again with very spotty emergence. Wide spread rain is greatly needed. For those that have caught rain, crops responded almost overnight in growth. I have seen some of the largest corn fields at V3-4. PRE herbicide activation has been a concern with limited rainfall. Wheat continues to be quite happy with continued modest temperatures overall in the 70s and 80s and no excessive precipitation. We will get a better view of the wheat crop across the region next Tuesday at the Illinois Wheat Association Plot Tour, where farmer groups will canvas many of our wheat producing counties across the state, assessing crop quality and yield estimates They will wrap up at the Belleville Research Center late afternoon to view plots and report crop observations.

Most fields in the area are planted and emerged. For the most part, the crop looks to be off to a good start in most fields, with the exception a few low spots where water is or was recently standing following the rains earlier this month. With minimal rain and some warmer temperatures in the near-term forecast, farmers in the area will likely finish up any planting and replanting they have to do in the next week or so.

2.8 inches of rain over the weekend. Water standing field work has been at a stand still for the last week and will be for another week. Just a few fields left to plant in the area., Either field corn or seed corn.

This soybean field has uniform germination and good plant stand.

Corn is up. This field was planted on May 4th and had about an inch and a half of rain after it was planted followed by warmer temperatures.

Had just 4 tenths of rain in June so far. Most crops still look good.. Lighter soils and sand fields are showing stress. Been applying about an inch of water per week for the last 3 weeks through irrigation.

We are starting to see some Black Cutworms in Western IL. Scout throughout the field and often.

Many farmers wrapped up planting this week or have a significant amount planted at this point in the season. We received critical and gentle rains that will help kickstart this season on the right foot.

Many farmers have been in the heart of planting this week and some are getting closer to finishing. We received critical and gentle rains that will help kickstart this season on the right foot.

This area received variable rains that halted planting. Some areas received anywhere from 0.75” to 5” early this week, and are receiving another 0.5” today. Planting is wrapping up for the area.

Fields near school pickup. 2 tenths of rain this morning. Need sunshine.

Last week brought a band of rain through our area with rain totals from .5″ to 4″. In the heaviest of the areas pond took 4-5 days to recede. There may be some replant in these areas. Other areas could use a half inch to aid in emergence of the last planted soybeans. Growers in Nothern Champaign and Southern Ford County postponed planting on 5/7 due to extremely hard soil conditions until after the weekend rain event passed.

Rain over the weekend through Monday was timely and provided much needed moisture. Some farmers are still working to finish planting the final fields.

Sunshine and heat, finally! Favorable growing conditions in NE Illinois. The sunshine, warmth, and needed rain gave a boost to both corn and soybean that had been slowly trying to emerge and grow. Despite concerns, I have heard few reports of emergence issues with seed sitting in cool soils for extended periods. This past weekend most areas measured between .3 to over an inch of rain. Isolated areas near Channahon and in Kankakee received 2+ inches. Soybean planting is starting to resume in the area.

Locally, we are still very dry overall. Rainfall has been very scattered with some areas having caught almost an inch, yet others not even a tenth so far. Temperatures have been moderate with highs in the 70’s to low 80’s, but some days have had a noticeable increase in humidity to more summer-like conditions. Most crops are emerged, but there are some acres left to plant. Soil moisture conditions for planting this spring have been the best I can remember for the last few years, compared with many, wet springs we have had in recent memory. The extent of the dry is starting to get concerning and most are hoping for a few inches of rain, even if they still have some acres to plant. Wheat is still looking very good, especially with the modest temperatures and dry weather. I have seen some fungicides applied earlier this week on wheat acres.

In my trip through South Central IL this past week, most fields I saw are still on the wet side. Most wheat fields are headed out and at least entering the anthesis (flowering) period. The wet soils kept the ground equipment out of many fields, but I did see at least a couple planes applying fungicide treatments.

I didn’t see much in the way of newly planted fields, and that which was planted in the last couple weeks has, for the most part, not yet emerged. That said, there were a few fields with emerged spring-planted crop. With more rain coming through this weekend, field operations will likely be delayed a bit longer in that region. But with a dry and relatively warm forecast next week, many are expecting to get back in the field.

Stand counts were taken and were really good on both corn and soybeans. There were a few patches of cereal rye that did not completely die at termination. After further inspection, we found that the seeding depth of the corn was 1 1/2 inches, which is a much shallower depth than planned.

The stands of soybeans appeared adequate for 30 inch rows. No signs of pests or other stress.

Mostly favorable growing conditions in NE Illinois. Spotty precipitation slowed some farmers who are trying to wrap up the 2023 planting season. Cooler soils slowed some soybean emergence, especially in high residue No-till fields. Those scouting soybean fields have reported some emerging soy exhibiting discolored cotyledons. Likely causes can include stressful emergence conditions, diseases, herbicide injury from pre-emergent herbicides (likely PPO-inhibiting herbicides whose injury to emerging soybeans is enhanced by cool and wet conditions). If the cotyledons have a distinctive “halo'” on the cotyledon and the soy planted was seed-treated with the fungicide fluopyram (ILeVO), the browning is the result of phytotoxicity caused by accumulation of the fungicide in the cotyledon. We encourage early season scouting but also suggest farmers observe their soybean fields for several days to a week of favorable growing conditions before making rash replant decisions. Soybean are a resilient crop that often outgrow early season issues.

We received 2 to 3 inches of rain in total over the previous weekend. This and the heat amazingly allowed the corn to break through the soil crust. Stands look so much better, but way too wet to take stand counts.

We received 3 to 3.5 inches total over the previous weekend. The hail events took place on Sunday, May 7th. Stand counts of soybeans were on the lower end before the hail. You are able to see regrowth already on soybeans thanks to warm days. We will need to reevaluate the stand at the end of the week if it does not rain again. The West side of the field is the worst. No hail injury across the county line into Montgomery County.

Several big storms over the weekend. Some ponding prior to the last one, expect more now. Tree damage, power outages, possible other damage.

2023 planting is nearly done with most farmers in the area finished planting. The dry April weather has allowed spring planting to progress quickly. The cool temperatures for the second half of April has slowed emergence and plant growth of plants that have emerged.

Planted on April 12th. Population of around 70,000 plants per acre, with many still trying to push through. We need a rain!

Planted April 18th and 19th. A few spikes can be seen coming through soil cracks. Soil is crusted, but corn remains ok beneath the sealed in soil. Dad is starting worry. We need rain!

Significant progress in planting both corn and soybeans has happened over the last 10 days. Some growers are nearing completion already! Planting conditions for corn have been relatively good, soybeans that went in early are struggling to emerge. The soil is tight and we need a rain shower to bring them the rest of the way

Wheat stands in south-central Illinois look good overall. There is some unevenness in plant heights visible across fields, which is fairly normal for the relatively flatter fields in that area, for this stage of wheat growth, and for this time of year. But the stands look good in general. Most fields I walked through or observed from the road are at or near boot stage with some in the early heading stages. Farmers are also making progress with spring planting, although very little has emerged due to the cool temperatures over the past few weeks. Also, with somewhat wetter conditions relative to much of the rest of the state, field operations have not taken place in many low-lying and/or poorly drained fields. With a rainy week ahead, some of those fields may remain unplanted for a bit longer.

All crops are planted. Corn growth stages vary from emerging to almost V3 with third leaf almost fully developed. Soybean are similar varying between just breaking through the ground to first trifoliate.

Reports of insect activity so far have focused on large/early flights of black cutworm and true armyworm, likely helped along by storms out of the southwest a couple of weeks ago. Both species are more likely to be a problem if dense vegetation is present in the field; black cutworms are especially attracted to winter annual weeds, while armyworm prefers dense grassy vegetation. Be on the lookout for seedling pests (including seed corn maggot, slugs, wireworms, etc.), which can become a problem when cool conditions delay emergence.

On May 3rd, on a crossroad survey of a 60 mile loop across northern and eastern Macon County, 80 percent of fields were planted. Corn emergence out-paced soybean emergence by about 6 to 1. The ratio varied greatly by neighborhood. The only field activity observed was widely scattered planting, dust clouds made it easy to spot.

Like many we are very dry. Despite the cool weather, the last few fronts that have passed through over the last few weeks have not left much more than a few tenths of rain. That coupled with the windy conditions, has really dried things out. We are on the down hill side of full season corn and soybean planting with the only major slow down in planting has been some cooler weather, however, that pattern is supposed to break for more spring-like temperatures. There are some corn and soybean fields up, but just barely enough that you can row them from the road. Even the earliest planted has been very slow to emerge with the cool weather and lows still dropping to near 40 degrees some nights. Wheat is appreciating the dry weather and modest temperatures and is looking very good. Hopefully we will catch some rain here in the next week!

We are likely in the cutting window in much of the state for black cutworm larvae. I have not received reports of damage yet; in addition to the timing of moth flights, note that the fields at risk of cutworm damage are generally those that have a problem with winter annual weeds – especially when those weeds are dying at around the time the crop emerges. If you had adequate, early control of these winter annuals, even a large moth flight is unlikely to result in much cutworm damage.

Continue to monitor corn and soybean fields for cutworms and armyworms. I have not had many reports of damage to this point – good early season emergence conditions go a long way towards helping the crop “outrun” this sort of damage. We ought to start seeing rootworm egg hatch over the next couple of weeks – I browsed degree day accumulations for several weather stations throughout Illinois, and most are relatively close to the 11 year average for this time of year (some a bit ahead, and some a bit behind).

Soybeans planted 4/10-13 are emerging with freeze and frost potential.

Damp and cold

Sprayers are out! The next few days will be great drying weather and I’ve heard Wednesday is the Go day for many farmers in McLean County.

Although some rain fell in much of the area this past Sunday, total rainfall was low (0.14” at the Illinois Climate Network (ICN) station in Champaign) and conditions remain dry in Champaign County. ICN soil moisture data show levels below the plant wilting point at 2” and 4” depths, however, at least where these instruments are in place, plant available moisture is still present at 8” and deeper. The lack of soil moisture at the shallower depths is evident when driving around the countryside. Corn plants in drier areas of fields are showing rolled leaves even in the morning hours. By the afternoon, the signs of moisture stress are more prevalent. Most corn plants are somewhere in the V5-V8 stages, and at that size, have at least some roots that are deep enough to reach the soil moisture still available. Soybeans may be struggling a bit more at this point, and their growth seems to have slowed in most fields. The plants still look relatively healthy, and the first flowers are starting to appear. But with little rain in the extended forecast, these early flowers are unlikely to contribute much to final pod counts.
