Tomato (Solanum lycopersicum L.) is one of the most popular vegetable crops. It is affected by several diseases among them early blight caused by Alternaria solani is most destructive foliar diseases of tomato, the present study was conducted to evaluate in vitro efficacy of different fungicides with four different concentrations (250, 500, 750 &1000 ppm). Among them highest percent inhibition was found in Propiconazole (90.19%) at 1000 ppm concentration after 120 hrs followed by Tebuconazole ( 86.52%), Mancozeb ( 80.63%) and Captan + Hexaconazole (79.40%) against A. solani. and Moderately growth was found in Hexaconazole (78.17%), Thiram (76.64%) Captan (74.73%) and Carbendazim ( 65.54%).
