Mark Carlton, extension crop specialist, and I found a field in Marion County on May 16 that had variegated cutworms feeding on young corn plants. The variegated cutworms were feeding on the leaves, chewing both circular holes and eating along the leaf margin. We did not find any variegated cutworms actually cutting corn plants or in the soil near cut plants, although the field did have black cutworms 1.5 inches in length and wireworms that were causing stand loss.
