Abstract: In the conducted field trials at G.H.R.U. School of Agriculture Sciences, Saikheda (M.P.), an investigation was carried out to assess the impact of chemical insecticides in conjunction with biopesticides on the gram pod borer,
Helicoverpa armigera, in chickpea crops. The experimental design followed a Randomized Block Design (RBD) with eight treatment modules, including a control. The treatments consisted of Emamectin Benzoate 5 g, Indoxacarb 14.5 SC, Flubendiamide 480 SC, Cypermethrin 25 EC, Quinalphos 25 EC, NSKE Neem seed kernel extract, and Bt (
Bacillus thuringiensis)
. Two spray schedules were implemented on the gram pod borer, and post-application of all sprays, Flubendiamide 480 SC demonstrated high efficacy in controlling the population, with only 0.88 larvae/mrl. Consequently, Flubendiamide emerged as the most effective treatment among all modules. Other treatments also exhibited significant control over the gram pod borer, with Emamectin Benzoate 5 g (1.07 larvae/mrl), Indoxacarb 14.5 SC (1.11 larvae/mrl), Cypermethrin 25 EC (1.21 larvae/mrl), Quinalphos 25 EC (1.38 larvae/mrl), Bt (
Bacillus thuringiensis)
(1.60 larvae per meter row), and NSKE Neem seed kernel extract (1.67 larvae/mrl).
Regarding grain yield, Flubendiamide 480 SC demonstrated its effectiveness by achieving the highest yield among all modules, i.e., 14-15 qt/ha.
