SYNOPSIS

Frequent rains over the past week have maintained adequate soil moisture levels in northern Vermilion County. As I conducted my survey on the morning of 7/31, light rain was falling once again. Despite the relatively wet conditions for this time of year, disease pressure remained low in the corn and soybean fields visited. In corn, the most common sight was the tell‑tale “inverted V” chlorosis/necrosis pattern showing up in the lower canopy, in areas where nitrogen is limited and the plant is remobilizing nitrogen toward grain fill. Most corn fields surveyed were in the R3 “milk” stage, with some still in late R2 “blister” stage. Soybeans were generally in the R3 “beginning pod” to R4 “full pod” stages, although a couple of fields surveyed were nearing R5 “beginning seed.”
