SYNOPSIS

I had the chance to drive west from Springfield, IL, on I-72 to Quincy, IL, then head toward Macomb, IL, before returning home. For the most part, corn and soybeans look great in this part of western Illinois. I evaluated one of the ISA sulfur plots near Macomb, IL, where soybeans were just beginning to flower. Corn is at the rapid growth stage (around V6). Post-spraying and side-dressing appear to be finished. I spotted a click beetle—possibly a sign of wireworm issues—near our plot, but soybean stands were adequate at around 100,000 plants per acre. No major diseases were found, though root rots such as Phytophthora could begin to show up with additional rainfall.
