Field experiment was conducted for the management of early blight of tomato through a number of fungicides viz., Mancozeb 75 WP (Indofil M-45, 75%), Difenoconazole 25 EC (Score, 25%), Copper Oxychloride 50 WP (Blue Copper, 50%), Ridomyl MZ 72 WP (Metalaxyl, 8% + Mancozeb, 64%), Chlorothalonil 75WP (Kavach, 75%) and biocontrol agent viz. Trichoderma viride. It was found that all the treatments were effective to reduce the severity of the disease. Among the treatments, seed treatment with Mancozeb followed by foliar spraying of the same fungicide was found most effective in both the years and was closely followed by foliar spraying with Difenoconazole. Percent disease control in two years pooled mean revealed that the maximum disease control was noticed in seed treatment with Mancozeb followed by foliar spraying of the same fungicide. A maximum increase of yield was also achieved with the same treatment.
