Abstract:

A field experiment was conducted to evaluate eight insecticides viz., Emamectin benzoate 5% SG @ 0.3 g/lit, Spinosad 45% SC @ 0.5 ml/lit, Thiacloprid 21.7% SC @ 0.3 ml/lit, Indoxacarb 14.5% SC @ 0.75 ml/lit, Imidacloprid17.8% SL @ 0.3 ml/lit, Thiamethoxam 30% FS @ 0.3 ml/lit, Chlorantraniliprole 18.5% SC @ 0.3 ml/lit and Cartap Hydrochloride 50 SP @ 1.5 ml/lit against cabbage aphid, Brevicoryne brassicae and cabbage butterfly, Pieris canidia on cauliflower. The result indicated that imidacloprid 17.8% SL recorded the highest (84.57 to 85.88%) reduction of aphid population followed by thiamethoxam 30% FS and thiacloprid 21.7% SC. The bio pesticide Spinoasd 45% SC recorded the highest (82.70 to 89.94%) reduction of cabbage butterfly population followed by emamectin benzoate 5% SG (80.15 to 83.28%). The benefit cost ratio was the highest in thiacloprid 21.7% SC (18.33:1) followed by thiamethoxam 30% FS (15.24:1) and Imidacloprid 17.8% SL (12.55:1).
