Two applications of seven insecticides were used against Earias vittella and the results revealed that Chlorantraniliprole 18.5% SC had the lowest per cent of shoot and fruit infestation with 11.71% and 11.96% followed by Emamectin benzoate 5% SG (12.96% and 14.11%), Spinetoram 11.7% SC (13.28% and 14.70%), Imidacloprid 17.8% SL (14.71% and 16.35%), Flonicamid 50 WG (14.90% and 17.31%), Acephate 75 SP (15.74% and 17.65%) and Diafenthiuron 50 WP (16.39% and 19.61%) respectively as compared to control (water spray) with 20.75% and 24.75%. Benefit cost ratio was found highest in Chlorantraniliprole (1: 4.4) followed by Imidacloprid (1: 4.2), Emamectin benzoate (1: 4.2), Spinetoram (1: 3.4), Diafenthiuron (1: 3.3), Flonicamid (1: 3.3), Acephate (1: 3.1) and Control (1: 1.6).
