Abstract:
Early blight of tomato disease caused by Alternaria solani (Ell. & Mart.) is one of the most devastating diseases of tomatoes. It is a potential tomato disease that is reducing production worldwide. To date, various treatments have been adopted to minimize the disease. The present study was based on the selection of chemical fungicides against A. solani in tomatoes that cause blight. The in vitro and in vivo efficacy of chemical fungicides showed that minimal radial growth with a diameter of 0.51 cm gave hexaconazole, followed by thifluzamide with a radial growth of 1.18 cm. In this study, five fungicides were used at a concentration of 100 and 300 ppm. The maximum suppression of fungi was provided by hexaconazole with 94.33% at a concentration of 300 ppm, fruits 35 / plant, fruit yield 1.224 kg / plant, 15.45 kg / plot, 252.50 q / ha.
