Greetings to all our NuTech customers for an agronomy update from Northern and Central Illinois. I wanted to share what I have seen in various areas of Illinois the last couple weeks.

NW Illinois: Corn crop coming along well, despite some flooding along the Mississippi and Rock River areas. Soybeans are small and very little bean leaf beetle feeding taking place.

Central Illinois: Corn is very far along with 2nd pass corn spraying nearing completion. Soybean replant has been plentiful, but nearly 99% of the crop in this area has been planted. Lexington area is very dry, our research plots there could use a rain and as of June 10th have missed most of the rains Illinois has been receiving.

Western Illinois: Corn growth stages range from recent replanting to some corn fields at V7 near Quincy. Most post spraying is completed on corn. Soybean planting near completion other than double crop and some replant acres along the Mississippi River.

NE Illinois: Corn is in all stages from V5 to some areas with some first-time planting taking place the first week of June. This area has been most effected by rains during the month of May. Soybean planting is still in full swing in this area, and many growers still replanting wet holes. See photo below.

Corn Herbicide Spraying: Recently I have had calls regarding post spraying in corn, much of the corn is very sensitive as the leaf cuticle on these plants is very thin. What does this mean? It means that you can easily see flashing taking place in the corn following post spraying. This often is surfactant burns on the plant and normally will grow out within 3-5 days.

Soybean Herbicide Spraying: I cannot stress this enough to have good communication with your herbicide applicator and seed seller. Currently there are (6) different technologies in soybeans and before any post herbicide applications are applied communication must take place to avoid potential issues. Recent high temps in the 90’s have created concerns with certain tank mix partners, understanding which residual products have higher oil concentration is critical before tank mixing to avoid burning soybean leaves.

Weed of the Month: Common Marestail (Horeseweed)

  • This weed is best controlled in the fall with several ALS products or even just using 2, 4-D prior to the ground freezing.
  • This weed is very difficult to control in the spring, and if you have Marestail that is tall (see photo below) then you need to call me to discuss options.
  • Winter annual weeds need to be controlled in the fall to allow the herbicide to be taken into the plant prior to freezing conditions.
