Insect IPM in Organic Field Crops: Seedcorn Maggot
Author(s) Katelin Holm, Eileen Cullen
The seedcorn maggot (SCM), Delia platura, is a soil insect pest of corn, soybean, and vegetable crops. Conventional SCM management methods of synthetic insecticide seed treatment and cover crop or weed herbicide burn-down are incompatible with organic agriculture.
This publication addresses cultural control integrated pest management (IPM) strategies for SCM in corn and soybean, including SCM identification, life cycle, crop damage symptoms, and the use of insect degree days to forecast fly-free periods during the growing season (6 pages; 2011).
