Insecticides for Soil Cutworm Control in Corn

Updated January 8, 2007 by Robert Wright

Economic Threshold:
Treat when 5% of plants are damaged or cut, and larvae are less than 1 inch long.
Cutworms longer than one inch are likely to pupate (i.e. cease feeding) before causing significant additional damage.

This list is not inclusive. See http://www.greenbook.net or other resources for additional registrations.
This information is presented in abbreviated form. Be sure to consult the label for additional information and restrictions.

Note: Pre-emergence or planting time applications are not generally recommended
for cutworm control in field corn in Nebraska.
