Abstract
The present investigation was carried out in a Randomized Block Design having 3 replications and 8 treatments (seven insecticides and one control) during kharif season 2023 conducted at the Central Research Farm, NAINI, SHUATS, Prayagraj (U.P). The order of effectiveness was observed in Chlorantraniliprole 18.5 EC (11.79), (8.01) > Spinosad 45 SC (13.52), (10.52) > Emamectin benzoate 5% SG (14.91), (11.41) > Beauveria bassiana 1% WP (16.00), (12.39) > Metarhizium anisopliae 1x108 CFU/gm (16.71), (13.46) > Neem oil 0.4% + Pongamia oil 0.1% (17.84), (14.79) > Neem oil 2% (20.03), (17.77) > untreated control plot (27.22), (32.12) based on percentage shoot and fruit infestation. While highest yield and benefit cost ratio was obtained in Chlorantraniliprole 18.5 EC (220.95 q/ha), (1:6.48) followed by Spinosad 45 SC (198.20 q/ha), (1:5.68), Emamectin benzoate 5% SG (170.87 q/ha), (1:4.98), Beauveria bassiana 1% WP (160.00 q/ha), (1:4.75), Metarhizium anisopliae 1x108 CFU/gm (140.69 q/ha), (1:4.13), Neem oil 0.4% + Pongamia oil 0.1% (125.50 q/ha), (1:3.68), Neem oil 2% (99.85 q/ha), (1:2.96). Lest monetary returns was obtained with untreated control plot (55.16 q/ha), (1:1.70).
