Field Efficacy and Economics of Selected Insecticides and Bio-pesticides against Chickpea Pod Borer [Helicoverpa armigera (Hubner)] on Chickpea (Cicer arietinum L.) at Prayagraj

At the Central Research Farm of Sam Higginbottom University of Agriculture, Technology And Sciences, Prayagraj, an experiment on chickpea was carried out to test the "Field efficacy and economics of selected insecticides and bio-Pesticides against chickpea pod borer [Helicoverpa armigera (Hubner)] on chickpea (Cicer arietinum L.) at Prayagraj" during rabi season of 2022-2023. Effectiveness of biopesticides and insecticides viz., T1 Chlorantraniliprole 18.5% SC 0.5ml ml/lit of water, T2 Emamectin benzoate 5% SG 0.4 gm/lit of water, T3 Novaluron 10% EC 1.5 ml/lit of water, T4 Spinosad 45% SC 0.5 ml/lit of water, T5 Beauveria bassiana WP 5 gm/lit of water, T6 Nisco sixer plus 1ml/lit of water and T7 Neem oil 5% @ 5 ml/lit of water and treatment of T8 Untreated control were tested against chickpea pod borer Helicoverpa armigera (Hubner). The different insecticides and biopesticides treatments revealed that all the treatments were superior over control, T1 Chlorantraniliprole 18.5% SC (0.66) which found most effective followed by T2 Emamectin benzoate 5% SG (0.87), T4 Spinosad 45% SC (0.98), T3 Novaluron 10% EC (1.11), T6 Nisco sixer plus (1.30), T5 Beauveria bassiana WP (1.48), T7 Neem oil 5% (2.15) and T8 Untreated control (6.02). The crop with the highest average yield, T1 Chlorantraniliprole 18.5% SC, produced 22.01 q/ha, and its cost-benefit ratio was 1:2.26. followed by T2 Emamectin benzoate 5% SG (21.09 q/ha) with 1:2.55 C:B ratio, T4 Spinosad 45% SC (19.75 q/ha) with 1:2.32 C:B ratio, T3 Novaluron 10% EC (17.5 q/ha) with 1:2.14 C:B ratio, T6 Nisco sixer plus (16.16 q/ha) with 1:2.02 C:B ratio, T5 Beauveria bassiana WP (13.29 q/ha) with 1:1.72 C:B ratio, T7 Neem oil 5% (13.03 q/ha) with 1:1.67 C:B ratio and T8 Control (9.5 q/ha) with 1:1.29 C:B ratio.
