SYNOPSIS

Across much of the area, there are entire fields of soybeans exhibiting cupping. The widespread nature of the symptom could point to environmental stress as the cause, potentially from the hot and dry conditions over the past week and a half. Many soybean fields are still not canopied.

Corn has greatly increased in height recently due to the accumulation of over 240 GDDs during the past week and a half. I have not seen, and there have not been any reports of, disease in corn thus far this season.
