Abstract
A field experiment was conducted during the Rabi 2024-25 at the GPB Research Farm, Acharya Narendra Deva University of Agriculture & Technology, Kumarganj, Ayodhya (U.P.), India to evaluate the efficacy and economic viability of bio-intensive pest management (BIPM) strategies for controlling Helicoverpa armigera (gram pod borer) in chickpea. Eight treatments, including synthetic insecticides (Tetraniliprole, Novaluron, Flubendiamide, Chlorantraniliprole), biopesticides (BARC Bt, DOR Bt), NSKE, and an untreated control, were assessed. Larval populations were recorded pre-application and at 3, 7, and 10 days post-spray. Tetraniliprole 18.18 SC exhibited the highest larval suppression (73.7% reduction) and the greatest yield (21.74 q/ha), while Chlorantraniliprole 18.5 SC demonstrated the highest cost-benefit ratio (1:18.2). Among biopesticides, BARC Bt (ISPC-1 bacterium) showed moderate efficacy. NSKE (5 %) yielded the lowest performance (1:1.0 ratio). The findings support Tetraniliprole and Chlorantraniliprole as effective, economically viable options for managing H. armigera, offering an integrated solution within sustainable pest control frameworks.
