Abstract

Microbial and chemical insecticides provided control of Pieris rapae (L.) and Trichoplusia ni (Hübner) on cabbage when applied to field plots based on predetermined densities of eggs and small and large larvae. In excess of 90% of cabbage harvested from plots treated with suspensions of Pieris rapae granulosis virus, Autographa californica nuclear polyhedrosis virus, and Bacillus thuringiensis were marketable. The protection of the crop by microbial insecticides was similar to protection in plots treated with chemical insecticides in which marketable heads exceeded 95%.
