Compatibility of biocontrol agents viz., Trichoderma viride, T. harzianum and P. fluorescens were studied with four Fungicides viz., Thiram @0.3%, Carbendazim @0.1%, Captan @0.3%, fosetyl AL @0.2%, in favour of tolerance to fungicides. It was indicated that radial growth of fungal biocontrol agent Trichoderma viride was significantly inhibited (100%) with Thiram (0.3%) and Carbendazim (0.1%). Growth of T. harzianum was also 100 per cent inhibited with Carbendazim (0.1%). Whereas, both fungal biocontrol agents had recorded compatible with Fosetyl AL (0.2%), which have less (57.59% and 1.3%) inhibitory effect on growth of T. viride and T. harzianum respectively. The bacterial bioagent viz., P. fluorescens was found to be more compatible with Carbendazim (0.1%) and Fosetyl Al (0.2%). Hence, fungicide contamination at given concentration in soil will not affect their effectiveness. Moreover, the fungicide tolerance ability broadened the use as these biocontrol agents in integration with fungicides can be applied for the management of soil borne plant pathogens under integrated disease management.
