Cutworms injure established fields by cutting off new growth or feeding on foliage.
Cutworms can be extremely frustrating to the grower because they are difficult to detect. They feed primarily at night and hide under debris or in cracks in the soil during the day. Cutworms develop in weedy areas, later moving into an alfalfa field. They often have stripes or spots on their back. When disturbed, cutworms curl up.
