Evaluation of insecticides against Helicoverpa armigera Hubner in chickpea

Abstract

The experiment was conducted at College Farm, College of Agriculture, Navsari Agricultural University, Bharuch-392 012 during rabi, 2021-22. Among all the insecticides significantly lowest population of H. armigera larvae was found in treatment of chlorantraniliprole 18.5 SC (0.31 larvae/plant) and it was at par with spinosad 45 SC (0.44 larvae/plant). Flubendiamide 39.35 SC (0.56 larvae/plant) was significantly at par with emamectin benzoate 5 WSG (0.63 larvae/plant) and indoxacarb 14.5 SC (0.67 larvae/plant). The significant minimum pod damage (8.49%), maximum chickpea seed yield (2202 kg ha-1), maximum increased yield over control (78.29%) was recorded in the treatment of chlorantraniliprole 18.5 SC at 0.006%.
