Abstract

Black cutworms are usually associated with damage to corn. But this year, cutworms are causing significant stand loss in some soybean fields throughout central and southern Iowa. I heard numerous reports of "hundreds of acres" being sprayed and some fields were replanted because of nearly complete stand destruction. The photographs illustrate 90-95 percent stand loss in a couple of V2- and V3-stage soybean fields near Farnhamville in Calhoun County. Carroll Olsen, field specialist in crops in southwest Iowa, noted that he has seen cutworms cause substantial damage to soybeans only twice in the last 20 years. Several other seasoned agronomists also noted that seeing cutworms in soybeans was a first for them.
