Late season western bean cutworm scouting is focused on looking for egg masses, which are usually deposited on the upper side of the upper most leaves.Īpplication of postemergence insecticides may be warranted for early season cutworm management when 6 to 8% of seedlings are cut above the ground or when 2 to 4% of seedlings are cut below ground. The presence of larvae can be confirmed by checking under crop residue or just below the soil surface and as they come out at night or overcast days to feed. When scouting for early season cutworm injury, look for leaf feeding, wilted plants, and missing plants.
