Early blight is one of the most damaging disease in tomato production areas worldwide incited by Alternaria solani. It reduces the quality and market value of tomato. This disease becomes serious when the season begins with abundant moisture or frequent rainfall by warm and dry weather which are unfavourable for the host and help rapid disease development. In the present study, fungi toxic activity of fungicides, namely Pyroclostrobin 25% EC, Hexaconazole 5% EC, Carbendazim 50% WP, Mancozeb 75% WP and Ridomil MZ 68% WG was evaluated by poisoned food technique at Laboratory of Plant Pathology, in the Division of Plant Pathology, Faculty of Agriculture, Sher-e-Kashmir University of Agricultural Sciences and Technology-Jammu, Chatha during the year 2017-2018. For the management of early blight of tomato caused by Alternaria solani. The results showed that all the tested fungicides at different concentrations significantly (P≤0.0001) inhibit the mycelial growth of the pathogen compared to control. Data regarding mycelial growth presented in the table 1 revealed that at 500 ppm, Pyroclostrobin was found most effective there by inhibiting the maximum mycelial growth (97.7%) of A. solani followed by Hexaconazole (91.1%) and carbendazim (90%). Ridomil was found least effective as inhibiting the mycelial growth only up to 42.2%.
