Experiment was carried out at the farmer’s field in the districts of Amritsar and Jalandhar to evaluate the efficacy of chlorantraniliprole 18.5SC, pyridalyl 10 EC and emamectin benzoate against the fruit borer Earias vitella in okra during 2019. The results revealed that after 7 and 10 days of treatment, chlorantraniliprole 18.5SC (125 and 150 ml/ ha) were found significantly superior and at par with pyridalyl 10EC (500 and 625 ml/ ha) and emamectin benzoate (175 g/ ha). Similar results were obtained with fruit yield wherein chlorantraniliprole 18.5SC (125 and 150 ml/ ha) was at par with pyridalyl 10EC (500 and 625 ml/ ha) and emamectin benzoate (175 g/ ha). Thus, chlorantraniliprole 18.5SC (125 ml/ ha) and pyridalyl 10EC (500 ml/ ha) can be alternative to the usually recommended insecticides against E. vitella.
