Abstract:

The current study was carried out at Central Research Farm, SHUATS, Naini, Prayagraj, U.P during kharif season of 2021. Two applications of seven insecticides were used against Eariasvittellaand the resultsrevealed that Chlorantraniliprole 18.5% SC had the lowest percent 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).
