Abstract:Spraying cabbage for control of Trichoplusia ni (Hübner) when larval populations were observed was more economical than spraying by calendar dates. Treatments should be made when the number of loopers present approaches 0.1 looper larvae per plant, to produce damage free marketable cabbage.
