Target leaf spot disease of soybean caused by Corynespora cassiicola. The disease affects leaves, stems, pods and seeds. Leaf lesions are rounded to irregular and reddish brown; they vary from specks to big mature spots. Lesions are frequently surrounded by a dull green or yellowish green halo. In this study, in vitro evaluation of six fungicides at two concentrations (50 and 100 ppm) revealed that four fungicides . Fluxapyroxad, Propiconazole, Tebuconazole and Hexaconazole completely inhibited the growth of the pathogen. Minimum inhibition of mycelial growth was recorded by Mancozeb and Pyraclostrobin in comparison to control at both (50 ppm and 100 ppm) the concentrations. |
