Cutworms are caterpillars live in the soil and can feed at the base of plant stems, causing plants to collapse.
Cutworm - turnip moth (Agrotis segetum)
A mixture of nematode species for controlling caterpillars and some other vegetable pests is sold as Fruit and Vegetable Protection and is available from some biological control suppliers. To be effective the nematodes need to be watered into moist soil while soil temperatures are in the range of 12-20ºC (54-68ºF) as soon as possible after purchase/delivery. These temperatures occur between April and September. Nematodes should be applied as soon as possible after purchase, following the suppliers’ instructions. It may be necessary to water the soil before and after application to ensure the soil is sufficiently moist for nematode activity and survival. Repeat application may be necessary.
