Abstract:
The experiment was conducted at the research plot of the Department of Agricultural Entomology at Central Research Farm, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj during the Kharif season of 2022. The trail was laid out in Randomized Block Design with three replications, Eight treatments were evaluated against Helicoverpa armigera viz., Flubendamide 20 WG@16gm/lit, Chlorantraniliprole 18.5% SC@0.3ml/lit, Spinosad 45% SC @0.6ml/lit, Fipronil 5% SC@0.1ml/lit, Emamectin benzoate 5% SG @ 0.4gm/lit, Lambda cyhalothrin 5% EC @ 1ml/lit, Imidacloprid 17.8% SL@0.5ml/lit and Control plot. Each insecticides was sprayed twice. Results revealed that, among the different treatments lowest pod damage percentage of green gram pod borer was recorded in Chlorantraniliprole (4.39) showed maximum mean percent pod damage i.e., followed by Spinosad (4.76), Flubendamide (5.15), Emamectin benzoate (5.57), Imidacloprid (6.07) and least effective treatment were Fipronil (6.27) and Lambda cyhalothrin (6.40). The highest yield of green gram was recorded with the spray application of Chlorantraniliprole (15.36 q/ha) followed by Spinosad (14.15 q/ha), Flubendamide (13.44 q/ha) and Emamectin benzoate (12.21 q/ha), Imidacloprid (11.31 q/ha), Fipronil (10.85 q/ha), Lambda cyhalothrin (9.24 q/ha) and the low yield was recorded from the plots sprayed with T₀ Control plot (4.00 q/ha). Among the treatments the best and most economical treatment was Flubendiamide 20% WG (1:2.49) followed by Chlorantraniliprole 18.5% SC (1:2.51), Spinosad 45% SC (1:1.70), Fipronil 5% SC (1:2.09), Emamectin benzoate 5% SG (1:2.13), Lambda cyhalothrin 5% EC (1:1.55) and Imidacloprid 17.8% SL (1:2.18) as compared to control plot (1:0.52).
