Seedling blight may occur from seed infections. Warm wet weather at R7 to R8 stages favors seed infection and decay. Seed, infected crop residue. Foliar fungicide at R6 stage in seed production fields if risk of seed infection is high. Pale green to yellow spots on upper leaf surface.
Lesions turn grayish brown to dark brown with a yellow or light green margin.
Tufts of gray fungal growth may be visible on lower leaf surface during moist weather. Severely affected leaves turn brown and drop. Whitish fungal growth may be present on interior of pods and seed coats. Systemically infected seedlings from infected seeds are stunted with mottled foliage. A common disease, but rarely causes significant yield loss.
