SYNOPSIS

Again, sounding like a broken record, hit or miss on rainfall for areas in NE Illinois. This past week some fields received inches while others received tenths. While management decisions are dwindling this late in the growing season, we can still learn from field visits. An area in a soybean field that from the road I predicted to be SDS or BSR turned out to be White Mold. While scouting I’m also noting vines becoming more visible, most on field edges, predominantly morningglories, but also Burcucumber. The morningglories can be frustrating during harvest, but Burcucumber can wrap on the reel and bring harvest to a stop. If you find areas with significant amounts of Burcucumber you may consider a harvest aid treatment. We are almost R5 for both crops, near dent stage in our corn and at or near beginning seed in our soybean. Continued low insect and disease pressure in fields I have visited.
