Bio-efficacy of novel insecticides against gram pod borer, Helicoverpa armigera (Hübner) and their impacts on natural enemies in chickpea

Six treatments viz., Chlorantraniliprole 18.5% SC @ 100, 125, 150 ml/ha, Emamectin benzoate 5% SG @ 220 g/ha, Quinalphos 25% EC @1000 ml/ha and untreated control were applied separately against H. armigera at economic threshold level. After two sprays, minimum larval population was recorded in the treatment Chlorantraniliprole 18.5% SC @ 150 ml/ha followed by Chlorantraniliprole 18.5% SC @ 125 ml/ha and Emamectin benzoate 5% SG @ 220 g/ha. Minimum pod damage (9.33%) was observed in treatment Chlorantraniliprole 18.5% SC @ 150 ml/ha with highest yield of 2817 kg/ha followed by treatment Chlorantraniliprole 18.5% SC @ 125 ml/ha with yield of 2790 kg/ha and both treatments were on par with each other. All tested insecticides were safe to natural enemies viz., coccinellid beetles and had no phyotoxic effect was recorded on chickpea crop.
