STUDIES ON GRAM POD BORER, HELICOVERPA ARMIGERA (HUBNER) AND ITS BIORATIONAL MANAGEMENT ON CHICKPEA.

The present investigations were carried out at the Student's Instructional Farm, Nawabganj of C. S. Azad University of Agriculture and Technology, Kanpur during Rabi season 2021-22 and 2022-23. All the treatments were found significantly superior over control, spinosad 45% SC performed best among the treatments followed by indoxacarb 14.5% SC. The effectiveness of treatment determined in the terms of grain yield of chickpea obtained in different treatments revealed that the spinosad 45% SC, indoxacarb 14.5% SC and Bacillus thuringiensis @ 1.5 kg/ha were significantly superior over untreated control. Spinosad 45% SC, gave maximum grain yield of chickpea in compared to other treatments as well as in managing the population of H. armigera. Besides indoxacarb 14.5% SC and Bacillus thuringiensis @ 1.5 kg/ha were found the second and third most effective treatments, respectively. [ABSTRACT FROM AUTHOR]
