Abstract
In the present study, efforts were made to explore the possibility of using Beauveria bassiana and Metarhizium anisopliae aione or in combination with different insecticides for the management of white grubs in green gram. B. bassiana formulation applied @ 5×1013 conidia ml−1 in combination with imidacloprid 200SL at 48g a.i. ha−1 was found to be effective exhibiting lowest plant mortality (1.66%) and lowest grub population (1.60/pit), which resulted in highest yield of 6,83q ha−1. Likewise M. anisopliae when applied @ 5×1013 conidia ml−1 in combination with imidacloprid 200SL at 48g a.i. ha-1 resulted in lowest plant mortality (2.28%) and grub population (1.12/pit) and highest yield of 6.79q ha-1.
