CAMB Bt. based and fungus based biopesticides, commercial Bt. formulation from mycogen and a new chemical pesticide Methoxyfenozide (RH2485-240SC) were tested on cauliflower field against cabbage butterfly (Pieris brassicae). All pesticides successfully controlled the population of cabbage butterfly in cauliflower crop. The efficacy against I to V instar larvae and field stability of CAMB Bt. biopesticide was better than chemical and other biopesticides. So, CAMB Bt. can be safely recommended for pest management strategies against Lepidopteral pests on vegetables with no harmful effects on its predators as in case with chemical pesticides.
