Tomato (Lycopersicon esculentum Mill.) is an important commercial vegetable of the world. Tomato cultivars cultivated in Pakistan have low level of genetic resistance to Alternaria leaf blight disease. Farmers, in pursuance of high yield are inclined to cultivate some varieties which may be less resistant to the disease and rely on fungicide applications for the control of Alternaria solani, the casual organism of Alternaria blight of tomato. Five tomato varieties (Litah545, Litah514, Eurica, Ti-166 and Astra) were sown in five replications with one standard check in tunnel. Different doses of mancozeb (4 g/L, 8 g/L, 12 g/L and 16 g/L of water) were applied after 7 days intervals. Disease data was recorded after ten days interval from flowering stage to onward. Average yield of each variety was calculated after ten pickings. All fungicide doses reduce the disease severity as compared .. View More»
