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.

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.

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.

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 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.

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).

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.

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.

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.

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.
