Abstract:
Tomato (Solanum lycopersicum) is an important vegetable crop after potato and predominantly grown in almost all tracts of world. Early blight of tomato caused by Alternaria solani emerged as one of the major foliar diseases of tomato. As Trichoderma viride established as one of the potential biocontrol agents for the control of fungal diseases, there is a need for testing the efficacy of Trichoderma viride with fungicides which are used against early blight. The invitro compatibility of Trichoderma viride with fungicides viz., Copper oxy chloride, azoxystrobin, Chlorothalonil, Antracol, Azoxystrobin+Difenconazole and Hexaconazole conducted to minimise the excessive use of chemical fungicides as part of an integrated disease management. The compatibility was tested at every 24 hrs after inoculation upto 7 days. The fungicides such as COC (0.1%, 0.2%) azoxystrobin and antracol found to be highly compatible with Trichoderma viride. Hexaconazole even at lower concentration 0.05% found to be highly incompatible and showed 100% percent inhibition on the growth of the antagonist at all tested concentrations from 24 hrs. to 168 hrs. of inoculation. Whereas azoxystrobin+Difenconazole and chlorothalonil @0.05 and 1% concentration and have showed minor inhibitory effect on Trichoderma viride.
