Field efficacy of some newer insecticides along with biopesticides against major insect pests in broccoli

An experiment was conducted to test the efficacy of certain new insecticides and biopesticides against major pests of broccoli at College of Agriculture, Rajendranagar, Hyderabad, India. There were nine treatments viz., acetamiprid 20% SP @ 0.2 g/L, Bacillus thuringiensis subsp. kurstaki @ 2 g/L, Beauveria bassiana @ 5 g/L, cyantraniliprole 10.26% OD @ 1.2 ml/L, chlorantraniliprole 18.50% SC @ 0.3 ml/L, diafenthiuron 50% WP @ 1.2 g/L, emamectin benzoate 5% SG @ 0.4 g/L, fipronil 5% SC @ 2 ml/Land Metarhizium anisopliae @ 5 g/L along with untreated control replicated thrice. The treatment cyantraniliprole 10.26% OD @ 1.2 ml/L was the most effective in management of Plutella xylostella, Crocidolomia pavonana and Spodoptera litura population followed by chlorantraniliprole 18.50% SC @ 0.3 ml/L and emamectin benzoate 5% SG @ 0.4 g/L. In case of Myzus persicae, acetamiprid 20% SP @ 0.2 g/L proved to be the most effective treatment showing maximum reduction in M. persicae population followed by cyantraniliprole 10.26% OD @ 1.2 ml/L and chlorantraniliprole 18.50% SC @ 0.3 ml/L.
