Black cutworm (Agrotis ipsilon) is an occasional pest of seedling beans and peas that results in cut or missing plants. Cutworms are more common in areas of reduced tillage and poor drainage. Larvae are light gray to tan in color with a faint stripe down the center of the back and dark spots on each body segment. Fully grown larvae can reach a length of 13/4 inches. They often curl up into a C-shaped position when disturbed. Cutworms are night feeders and can be found hiding under debris or in soil near plants during the day.

Management: 

• Soil cultivation disrupts day-time hiding.
• Effective weed control eliminates egg-laying areas and feeding grounds for larvae.
• Scout frequently until first true leaves are formed.
