The experiment was conducted at the research plot of the Department of Entomology at Central Research Farm (CRF), Sam Higginbottom University of Agriculture, Technology And Sciences, Prayagraj, during the Kharif season of 2022. The experiment was laid out in a Randomized Block Design (RBD) with three replications, seven treatments and untreated control were evaluated against, Scirpophaga incertulas i.e., Chlorantraniliprole 0.4% G @ 10kg/ha, Spinosad 45% SC @ 200ml/ha, Acephate 75% SP @ 650gm/ha, Emamectin benzoate 5% SG @ 220gm/ha, Bacillus thuringiensis 2ⅹ108 CFU @ 1000gm/ha, Neem oil 5% @ 5lit/ha, Karanj oil 5% @ 5lit/ha and Control. Among the different chemicals and biopesticides, the lowest per cent dead hearts and white ears was recorded in Chlorantraniliprole 0.4% G (4.24%), followed by Spinosad 45% SC (4.54%) and Acephate 75% SP (4.94%). The next best treatments were found to be Emamectin benzoate 5% SG (5.50%), Bacillus thuringiensis 2ⅹ108 CFU (5.71%), Neem oil 5% (5.99%), Karanj oil 5% (7.0%) and the highest dead heart and white ears % infestation of Scirpophaga incertulas (Walker) was found in control treatment (14.00%). The highest yield and cost benefit ratio was recorded with Chlorantraniliprole 0.4% G (69.33 q/ha) and (1:4.7) followed by Spinosad 45% SC (62.16 q/ha) and (1:3.5), Acephate 75% SP (48.33 q/ha) and (1:3.9), Emamectin benzoate 5% SG (41 q/ha) and (1:3.47), Bacillus thuringiensis 2ⅹ108 CFU (37.66 q/ha) and (1:2.47), Neem oil 5% (29.33 q/ha) and (1:1.87), Karanj oil 5% (22.77 q/ha) and (1:1.8).

The research work was undertaken at Central Research Farm (CRF) Sam Higginbottom University of Agriculture Technology and Sciences (SHUATS), Naini, Prayagraj during Rabi season in 2022- 23. Experiment consists of eight treatments including control viz. Chlorantraniliprole 18.5 SC @ 0.3ml/lit, Emamectin benzoate 1.9 EC @ 5ml/lit, Bacillus thurigiensis 1x109 CFU/ml @ 2.5g/lit, Spinosad 45 SC @ 0.3ml/lit, Indoxcarb 14.5 SC @ 0.5ml/lit, Metarhizium anisiopilae 1x109 CFU/ml @ 2.5gm/lit, Beauvaria bassiana 1.15 % WP @ 2.5gm/lit and untreated control in Randomized Block Design (RBD) with three replications. Data was taken on the mean larval population of chickpea pod borer Helicoverpa armigera on third, seventh and fourteen days after spray. Spraying revealed that the treatment Chlorantraniliprole 18.5 SC (2.36) found to be superior followed by Spinosad 45 SC (2.70), Emamectin benzoate 1.9EC (2.77), Indoxcarb 14.5 SC (2.98), Bacillus thurigiensis 1x109 CFU/ml (3.17), Beauvaria bassiana 1.15% WP (3.45), Metarhizium anisiopilae 1x109 CFU/ml (3.79) was found to be least effective among all the treatments as compared to control (5.64). Based on yield and cost benefit ratio the best and most economical treatment was Chlorantraniliprole 18.5 SC (26.83 q/ha) (1:3.49), followed by Spinosad 45SC (23.08 q/ha) (1:2.83), Emamectin benzoate 1.9EC(20.03q/ha) (1:2.66), Bacillus thurigiensis 1x109 CFU/ml (17.50 q/ha) (1:2.32), Indoxcarb 14.5 SC (17.66 q/ha) (1:2.29), Beauvaria bassiana 1.15 % WP (12.00 q/ha) (1:1.60), Metarhizium anisiopilae 1x109 CFU/ml (11.08 q/ha) (1:1.47) and untreated control (9.08) (1:1.27) ratio.
