Type: article
Abstract: An experiment was conducted during kharif season of 2022-2023 to evaluate the cost benefit ratio by using different insecticidal applications viz., Chlorantraniliprole 18.5 SC (0.5ml/l), Spinosad 45 SC (0.4ml/l), Nisco sixer plus (2ml/l), Bacillus thuringiensis 4% WSP (2gm/l), Beauveria bassiana 1.15% WP (5gm/l), Neem oil @2% (5ml/l), ½ dose Chlorantraniliprole + Nisco sixer plus (2.25ml/l) and Control plot against gram pod borer, Helicoverpa armigera (Lepidoptera, Noctuidae) on the green gram with three replications. Results revealed that the highest grain yield was recorded in (T1) Chlorantraniliprole 18.5 SC (15.6 q/ha) followed by (T2) Spinosad 45 SC (14.8 q/ha), (T7) Half dose Chlorantraniliprole + Nisco sixer plus (13.8 q/ha). Insecticidal treatment with (T1) Chlorantraniliprole 18.5 SC (1:2.87), followed by (T2) Spinosad 45 SC (1:2.79), (T7) Half dose Chlorantraniliprole + Nisco sixer plus (1:2.45), Nisco sixer plus (1:2.36), Beauveria bassiana 1.15% WP (1:2.30), Bacillus thuringiensis 4% WSP (1:2.00) and Neem oil @2% (1:1.83) are found to be least effective but comparatively superior over the control (1:1.51). End of the experiment it was reported that Chlorantraniliprole is the best for the management of gram pod borer.
