Cutworms (Agrotis spp)
Cutworms are caterpillars of some moths. The caterpillars live in the soil and eat into tubers boring a wide shallow hole. They are also serious pests of newly sprouted potato plants, and can leave empty patches in a potato field.
- Protect plants by wrapping them with collars. A simple collar can be made from cardboard tubes from paper towels or toilet paper (cut to size). This practice is time consuming, but it is effective and practicable in small fields.
- If necessary spray neem extracts. Neem leaf extracts and neem seed extracts (1 kg/40 l water) have been effective against cutworms attacking potatoes reducing damage significantly in Sudan.
