TAILIEUCHUNG - Compatibility of Trichoderma viride and Trichoderma harzianum with fungicides against soil borne diseases of tomato and cabbage

A study was undertaken to evaluate the compatibility of commonly used fungicides at recommended dosages with T. viride and T. harzianum being used as a biocontrol agents against soil borne diseases of tomato and cabbage under in vitro and in vivo conditions. Results indicated that among systemic fungicides, Azoxystrobin was found highly compatible with T. viride and T. harzianum at all the three tested concentrations (, and %) followed by Metalaxyl. With respect to non-systemic fungicides, Mancozeb recorded least inhibitory effect on Trichoderma sp. Further compatible combinations were evaluated in vivo to know the survival population of Trichoderma in soil media cropped with tomato and cabbage. Compatible combinations at their recommended dosage can be recommended for integrated management of soil borne pathogens of these crops. | Compatibility of Trichoderma viride and Trichoderma harzianum with fungicides against soil borne diseases of tomato and cabbage
