In countries like India insecticides play an important role in horticulture sector. Their importance in crop yield improvement, especially in Grape production, is understood and well accepted. But still they pose a threat to the environment due to their toxic nature and persistence in the food chain. Therefore, the study focuses on the development of a method to reduce the environmental burden of the insecticides by way of biodegradation. During this study, 7 different Bacillus strains isolated from grape rhizosphere soils were found to show significant tolerance ability towards an organophosphorus insecticide, Dichlorvas. Results indicated that out of 7 strains, only one strain could degrade the insecticide at the level of 10mg/L and 15mg/L. Also, the degradation of Dichlorvas was enhanced when medium was provided with glucose as an inducer for growth of bacteria.
