Abstract

Different fungicides and bio-agents were evaluated as foliar spray against buck eye rot early blight, late blight and Septoria leaf spot of tomato (Lycopersicon esculentum Mill.) under sick field conditions. All the fungicides and bio agents gave the significantly reduction in the severity of buck eye rot, early blight and Septoria leaf spot diseases of tomato significantly increase in yield over the control. Among the treatment Mancozeb is most effective in relation to severity of buck eye rot (22.33%) early blight (21.66%) and Saptoria leaf spot (23.29) which gave disease control of buck eye rot 68.17%, early blight 70.12% and Saptoria leaf spot 69.24% over the control (70.16%, 72.50% and 71.65 of the respective diseases) and thereby resulting in 77.20% increase yield as compare to control. Trichoderma viride and Trichoderma harzianum applied as foliar spray for control of above diseases of Tomato but least effective to control the disease.
