Abstract

A field experiment on evaluation of biopesticides against gram pod borer (Helicoverpa armigera Hub.) on pigeon pea was carried out during kharif season of 2012-13. The experiment was laid out in randomized block design with three replications. Gram pod borer is a major pest  of pigeon pea in India. For the management of this pest seven biopesticides were tested along with control. Among the biopesticides, Beauveria bassiana @ 1 liter / ha (1x1012 spores/ml) was found to be most effective biopesticide as it recorded lowest larval population (6.68 larvae / 5plants). The highest larval population was recorded in control (12.61 larvae /5 plants). The least effective treatment was  Paecilomyces fumosoreseus (9.31 larvae /5 plants). Similar trend was observed in the grain yield as 1667.55 kg/ha, 709.41kg/ha and 1025.21kg/ha , respectively.
