Description
Summary:ABSTRACT Diamondback moth (DBM) and cabbage butterfly (CB) are serious cabbage yield limiting factors in India. Considering insecticide resistance development in these pests, a study was conducted to find out the effective chemical molecule for managing these pests. Several novel insecticides were evaluated against Diamon back moth (DBM) and CB during spring season of 2019 and 2020. Efficacy of insecticides was determined by comparing larval densities of each insect species, immature and adult of natural enemies, crop damage ratings and marketable yield in insecticide treated versus untreated control plots. Spinetoram 45 and 60 g a.i. per ha recorded significantly higher larval population reduction (>80%) with least crop damage ratings (< 2) for both the insect pest population. Spinosad, emamectin benzoate, indoxacarb and chlorantraniliprole were also the found best treatments in controlling DBM and CB. No phytotoxic symptoms were observed in any treatment after spray application. Chlorpyriphos, deltamethrin, lambda-cyhalothrin and flubendiamide were found adverse to natural enemies. Thus, spinetoram, spinosad, emamectin benzoate, indoxacarb and chlorantraniliprole are recommended to manage DBM and CB on rotational basis in the cabbage ecosystem.
