Biological control involves the use of antagonistic microorganisms to attack and control plant pathogens, diseases and the disease producing activities they cause. It is an environmentally acceptable and ecologically viable approach which is compatible with different models of disease management i.e., organic, biological and integrated disease management (IDM) programmes. The chief antagonist used for disease management in Agriculture is the fungus Trichoderma viride, an effective and low cost biocontrol agent that can establish itself in different pathosystems. Nine fungicides namely Azoxystrobin, Iprodione, Tebuconazole, Hexaconazole, Propiconazole, Carbendazim and Thiopanate Methyl at 25, 50, 100 ppm and two fungicides viz., Captan and Mancozeb at 50, 100, 200ppm concentration were evaluated for their compatibility with the bioagent Trichoderma viride using poisoned food technique. The data showed that all fungicides significantly reduced the radial growth of Trichoderma viride. Mancozeb showed least inhibition (42.96%) at 200 ppm and compatible with Trichoderma viride. In case of five other fungicides Azoxystrobin, Tebuconazole, Hexaconazole, Propiconazole and Carbendazim completely inhibited the growth and not compatible with Trichoderma viride, while Thiopanate Methyl, Iprodione and Captan exhibited intermediate inhibitory effect and less compatible with Trichoderma viride.
