Delia radicum

cabbage maggot, cabbage fly, cabbage root fly

These small white maggots feed on stems and roots of brassicas including broccoli, cabbage, and cauliflower, a problem that is worst early in spring. May avoid most of the problems by setting these out around the last frost date, and by planting in areas where brassicas haven't grown in the last few years

Parasitic nematodes are commercially available. Wood ashes or diatomaceous earth may deter these pests; metal or cardboard collars surrounding plant stems and roots may help. Make sure no wild mustards, or other brassica-family weeds, grow nearby. Destroy infected plants.
