ABSTRACT
Chickpea (Cicer arietinum L.) is one of the most important legume crop. The gram pod borer, Helicoverpa armigera is considered to be the most serious insect-pest attacking this crop from vegetative to pod formation stage. Field experiment was conducted to evaluate the bio-efficacy of Emamectin benzoate against pod borer, Helicoverpa armigera at Agricultural Research Station, Mandor during rabi season, 2018-19. The experiment was laid out in Randomized Block Design with 6 treatments including untreated control. Different insecticidal treatments were Emamectin benzoate 5% SG @ 170, 220 and 270 g/ha (T1, T2, T3, respectively) , Lambdacyhalothrin 5% EC @ 500 ml/ha (T4) , Quinalphos 25% EC @1000 ml/ha. T5 After two sprays, minimum larval population was recorded in the treatment T3 followed by T2. Minimum pod damage (8.00 %) was observed in T3 with highest yield of 3280 kg/ha. However, it was on par with T2 (8.67%) with yield of 3065 kg/ha. Emamectin benzoate 5% SG @ 170, 220 and 270 g/ha was found safer to natural enemies viz., Coccinellid beetles and had no phyotoxic effect on chickpea crop. Considering the results, T2 was found to be most effective in protecting the chickpea crop from the incidence of H. armigera.
