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. Since it is an economically important disease, management of the disease plays crucial role. Poisoned food technique was employed for the evaluation of fungicides in the laboratory. Six fungicides viz. Dithan M45 (Mancozeb75%WP), Hexaconazole 5SC (Contaf), Propiconazole 25EC (Tilt), Tebuconazole 250EC (Folicur), Pyraclostrobin, Fluxapyroxd were evaluated against M. roridum. Two concentrations i.e., 50 ppm, 100 ppm, of each treatment were used. In this study, in vitro evaluation of six fungicides at two concentrations (50 and 100 ppm) showed that Propiconazole, and Pyraclostrobin most effective in inhibiting the mycelia growth of M. roridum.
