Western Bean Cutworm Larvae in Corn in Northwestern Illinois
It's time to begin checking cornfields for western bean cutworm egg masses and young larvae, especially where moths have been captured. Don't wait to find larger larvae, as it is very difficult to control them when they begin feeding in the ear tips.

Bean Leaf Beetle Densities Expected to Increase: Don't Underestimate Potential Impact of Insect Injury to Soybean Pods
Be vigilant and monitor fields for excessive defoliation and pod injury in the coming weeks. Bean leaf beetles, grasshoppers, and stink bugs are all able to cause yield losses in soybean fields during the pod-fill stage of development.

Bacterial Blight
Ragged, tattered, brown-speckled soybean leaflets are showing up in some fields in the central part of Illinois--characteristic of the bacterial leaf disease known as bacterial blight.

Sudden Death Syndrome--What's Up This Year?
Sudden death syndrome in soybean can be difficult to control. Management recommendations for lessening its impact are outlined.

Regional Reports
Reports are provided this issue for southern and west-central Illinois.
