Evaluation of combined insecticide for the management of pigeonpea pod borer

Abstract

A field study was conducted during 2024-2025 at Entomology Section, College of Agriculture, Nagpur (Maharashtra) to evaluate the efficacy and cost-effectiveness of nine combination insecticides against the Pigeonpea pod borer (Helicoverpa armigera). Among the evaluated insecticides, Chlorantraniliprole 9.3% + Lambda-cyhalothrin 4.6% ZC was the most effective treatment with lowest larval population of pod borer along with recording highest grain yield (14.03 q/ha). ICBR data revealed superiority of Thiamethoxam 12.6% + Lambda-cyhalothrin 9.5% ZC with the highest ICBR of 1:9.09 with net returns of ₹ 47,751/ha.
