In a year with delayed planting and struggles to get the crop planted I thought about changing my topic from Sclerotinia stem rot (Soybean White Mold) to a different topic. But if we look at the early planted soybeans getting close to closing the rows and the possibilities of a wet summer, we need to manage the crop that is in the ground to maximize yield. Understanding White Mold: Soybean white mold (SWM) is a disease that infects soybeans at the flowers, and then moves to the pods and stems at the node. It gets its name from the [...]
The recent wet weather has caused planting problems for Illinois growers. If you were lucky enough to soybeans planted, how much stress is your crop experiencing? In this podcast, CCA Soy Envoy, Todd Thumma talks about corn and soybean stress and what strategies should be used to help your crops overcome it.
As rain and cool conditions have delayed planting for many growers across Illinois and the Midwest, I’ve been having more than a few conversations around what we can do to minimize yield losses when planting soybeans later. Delayed planting reduces vegetative growth and the number of nodes on a plant, and the number of nodes can have a very direct impact on yield. Reduced vegetative growth also reduces the opportunity to have the rows close over prior to flowering, reducing the total amount of light interception from each acre which directly impacts yield. We can manage both if planting [...]
Every soybean producer in Illinois is also a corn producer. And one of the commonalities about farming in Illinois is that sometimes it will rain in the spring and delay or prevent planting. There comes a point in time that growers must decide whether to switch maturities or even switch crops (switching from corn to soybeans). There are several things to consider in that decision and the most likely is which will be most profitable. On average, hybrids will only lose one bushel for every 10 days of planting delay prior to May 10th. Planting dates after May 10th [...]
Every meeting this winter presenters talked about planting soybeans early. We must remember that the first major factor in raising any crop is the soil conditions at planting time, not what the calendar says. To ensure the crop gets off to the best start possible, seed should be planted into good soil conditions. We want all the plants to come up within 24 (if not 12) hours of each other under ideal emergence environments. Otherwise, plants that emerge later than the rest of the stand will struggle to catch up and will effectively be sapping nutrients and resources away [...]

With more acres of soybeans being planted and more dropped ears during corn harvest, volunteer corn is becoming a larger issue for Illinois growers. Areas across Northern Illinois experienced 2018 harvest conditions where some of the corn crop didn’t make it to the bin. After the combine had harvested a corn field, it wasn’t uncommon to have more than 10 bushels/acre of grain left in the field. We also experienced weather conditions that were not conducive to fall tillage which helped lost ears germinate, in many cases before a winter freeze. Volunteer corn competes with soybeans for nutrients, water [...]

Engenia® Herbicide, XtendiMax® With VaporGrip® Technology or FeXapan™ Herbicide Plus VaporGrip® Technology in Roundup Ready 2 Xtend® Soybeans Engenia, XtendiMax With VaporGrip Technology and FeXapan Plus VaporGrip Technology may now be available in your state for preemergence and postemergence use on Roundup Ready 2 Xtend soybeans. These dicamba containing herbicides now give growers postemergence product options to control troublesome weeds like waterhemp, Palmer amaranth, Giant ragweed, and marestail in Roundup Ready 2 Xtend soybeans. These herbicides are single mode of action group 4 herbicides- (synthetic auxins). It is highly recommended, for maximum weed control and resistance management, to use multiple [...]
Dicamba Symptomology and Yield Impact on Non-Dicamba Tolerant Soybeans In 2016, many states saw a rapid increase in acres planted to dicamba-tolerant soybeans. Many of these states experienced numerous cases of dicamba off-target movement due to vapor-drift, physical drift, tank-contamination and or use of an improper dicamba formulation. In this article, we will focus on how to identify dicamba symptomology on non-dicamba-tolerant soybeans and estimated yield impact of an off-target application of dicamba to non-dicamba tolerant soybeans. Dicamba symptomology is often not expressed until 7 to 14 days after application on non-0dicamba tolerant soybeans. After 7 to 14 day [...]

We experienced one of the wettest springs on record across Illinois. This delayed planting and caused some replant conditions this season as well. With inevitable late planting of soybeans this year, here are some key points to remember: As soybean planting is delayed population increases are necessary to maximize yields and ROI Past research shows if you are planting the second and third week in June, a transition from 140,000 plants per acre to 180,000 has a positive ROI Maintain maturity at our latitude through June for maximum yield A one-week delay in planting translates into 2.8 days delayed [...]
The Illinois Soybean Association (ISA) checkoff and membership programs represent more than 43,000 soybean farmers in Illinois. The checkoff funds market development and utilization efforts while the membership program supports the government relations interests of Illinois soybean farmers at the local, state, and national level, through the Illinois Soybean Growers (ISG). ISA upholds the interests of Illinois soybean producers through promotion, advocacy, and education with the vision of becoming a market leader in sustainable soybean production and profitability.
