Trichoderma viride can thrive in diverse environmental conditions as aggressive colonizers of soil and the roots of plants and act as natural bioagent to protect plants from infection by soil-borne fungal pathogens. Laboratory experiments were conducted to test the possibility of combining fungicides with T. viride to work out their compatibility to devise a suitable integrated management of soil borne plant diseases. A set of two isolates of T. viride namely T1 and T2 were used to evaluate compatibility with eight fungicides at five different concentrations. In-vitro compatibility study of Trichoderma spp with Mancozeb 75%WP revealed that this fungicide is compatible with Trichoderma viride upto 50 ppm. However, above 50 ppm concentration it started inhibiting the growth of both the isolates of T. viride. With thiram 75%WP, the maximum average per cent inhibition of 69.26 per cent was recorded at 1000 ppm which shows 30.74 per cent compatibility of Trichoderma with Thiram 75%WP at 1000 ppm concentration. However, Chlorothalonil 75%WP showed 75.29% inhibition in growth of T. viride at 1000 ppm concentration. Further, Tridemorph and thiophanate methyl showed only 100 % inhibition in growth of T. viride at 1000 ppm fungicide concentration.  In-vitro compatibility study of Carbendazim 50%WP, propiconazole 25%EC and Hexaconazole 5%EC revealed that these fungicides are not compatible with T. viride even at 50 ppm concentration and 100 per cent inhibition in growth of T. viride was observed at 50 ppm and above concentrations.
