SYNOPSIS

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.
