Efficacy of certain biopesticides and chemicals against gram pod borer [Helicoverpa armigera (Hubner)] on chickpea (Cicer arietinum L)

Abstract

The research work was conducted at Central Research Farm in Sam Higginbottom University of Agriculture Technology and Sciences, Naini, Prayagraj during rabi season in 2023-2024 includes eight treatments including and control viz, T1-Neem Oil 5%, T2-NSKE 5%, T3-Beauveria bassiana 1.15% WP, T4-Bacillus thuringiensis 1×109 CFU/ml, T5-Spinosad 45 SC, T6-Chlorantraniliprole 18.5% SC, T7-Profenofos 40% + Cypermethrin 4% EC and T0-untreated plot in Randomized Block Design used in three replications tormenting to study the efficacy of selected insecticides on the larval population of H. armigera on Chickpea. Result show that T6-Chlorantraniliprole 18.5% SC found superior among all treatments with larval population of (0.52) with highest C:B ratio and marketable yield (1:3.49 and 26.83 q/ha), and least effective among the treatments is NSKE 5% with a pest population, C:B ratio and yield (1.77, 1:1.75 and 13.33 q/ha).
