Myrothecium leaf spot of soybean caused by Myrothecium roridum. Myrothecium leaf spot of soybean is occurring in almost all the major soybean growing areas of India causing about 30 per cent yield loss. Initial symptoms of the disease appear as small round or oval, brown spots with dark brown margin on leaves in the infected plant. In study of the foliar spray of different chemical fungicides against myrothecium leaf spot of soybean under in vivo condition, fungicides viz., Tebuconazole, Hexaconazole, Mancozeb, Pyraclostrobin, Fluxapyroxad and Propiconazole were quite effective in reducing the percent disease index over control. Foliar application of Propiconazole (78.90%) was highly effective in reducing the percent disease index, followed by Pyraclostrobin (73.58%). Minimum percent disease index over control was observed in Tebuconazole (35.75%), followed by Fluxapyroxad (38.99%). These fungicides were also effective in reducing the percent disease index under field conditions.
