Abstract
A laboratory experiment was conducted to determine the bio-efficacy of Beauveria bassiana (Balsamo) Vuillemin alone and in combination with chemical insecticides against Helicoverpa armigera (Hubner) on pigeonpea at bio-control laboratory, Department of Entomology, College of Agriculture, Junagadh Agricultural University, Junagadh during Kharif season of 2011. The results revealed that polytrin-C 0.044 per cent and chlorpyriphos 0.05 per cent alone recorded the highest mortality, whereas B. Bassiana @1.25 kg/ha combined with polytrin-C 0.044 per cent and B. Bassiana @1.25 kg/ha combined with chlorpyriphos 0.05 per cent were the next best treatments and can be recommended for ecofriendly management of H. armigera in pigeonpea ecosystem.
