Infected seeds have irregularly shaped tan or light brown sunken lesions. Infected leaves appears as water soaked at first instance. They soon take on a greenish brown to reddish brown appearance. The infected portion later turns tan brown or black in colour. Under high rainfall or high humid conditions, a web like mycelial growth of fungus forms on the leaves. Dark brown sclerotia are formed on leaves and petioles. The pathogen survives as sclerotia in soil. Humid and cool (24-32o C) are favourable weather condition. Management Avoid dense planting. Completely cover plant residue by clean ploughing the field soon after harvest. Destroy infected stubble. Seed treatment with Thiram + Carbendazium (2:1) @ 3g/kg seed. Use Mancozeb or copper fungicide at 2.5gm/l or carbendazim 1 g/lit.
