The compatibility of bacterial biocontrol agent Bacillus subtilis was assessed with commonly used chemical fungicides viz., Carbendazim, Mancozeb, MetalaxylMZ, Wettable sulpher, Hexaconazole, Difenconazole, Tebuconazole and Kresoxim methyl. The compatibility was assessed at different concentrations and the concentration of 50, 100, 250, 500, 1000, 2000, 3000 and 5000 mg/lit for solid formulation fungicides and µl/lit for liquid formulation fungicides respectively. The compatibility tests revealed that among the solid formulation fungicides, the B. subtilis showed more tolerance to Carbendazim amd among the liquid formulation fungicides Hexaconazole and Kresoxim methyl showed maximum compatibility upto 3000µl/ l concentration. The fungicides viz., Carbendazim, Difenconazole, Hexaconazole and Kresoxim methyl compatible with B. subtilis at concentrations which were recommended for plant disease management i.e.1000 mg Carbendazim/l, 500 µl Difenconazole/l and 1000 µl each of Kresoxim methyl and Hexaconazole/l seem to be safe tolerance limit for B. subtilis. Moreover, the pesticide tolerance ability broadened the use as these biopesticides in conjugation with pesticides can be applied under integrated disease management for the management of soil borne plant pathogens.
