Management guide

Pest Description

The army cutworm caterpillar is a dull gray or gray-brown, less than 0.25 inch long. Adult moths emerge in summer and lay eggs in fall, where eggs remain dormant until spring. Canola is especially palatable to army cutworms. Treatment is necessary in years when army cutworm populations are high. Populations of 4 to 5 per square foot cause severe damage to stands.
