SYNOPSIS

I’m looking forward to another growing season and crop reporting in Northeast Illinois. April and May precipitation has slowed planting progress compared with other regions of Illinois. I’m estimating almost as much seed is still in the bag as is in the ground. On suitable days for planting, reports received suggest local farmers actively planted both soybeans and corn. The practice of planting soybeans ahead of corn acres has been adopted by many. Whether corn or soybeans, I was impressed by the acreage planted in a limited time frame. Despite planting date, low accumulations of GDDs have slowed crop emergence.

With limited emerged crops, we will highlight insect pests found in alfalfa. While sweeping alfalfa, we netted alfalfa weevil larvae, aphids and bean leaf beetles. We will continue to monitor leaf feeding in the alfalfa crop to determine whether a management threshold is reached.
