• All plant parts are affected.
• Symptoms appear on leaves as water soaked lesions.
• Symptoms include smaller circular brown spots on leaves.
• Under favorable conditions, these spots enlarge rapidly and coalesce, blighting the leaves and buds.
• In case of severe infection, the entire plant dries up suddenly.
• The lesions are also developed on stems and petioles.
• Late infections result in shriveled and infected seed.
• The disease is seed borne in nature.
• Left over debris in the fields serve as a source.
• Wet and warm weather, and dense crop canopy are conducive to the spread of the disease

Management

• Sow disease-free seed.
• Follow rotation crop.
• Intercrop with wheat, barley, mustard
• Seed treatment with Carbendazim @ 1g/kg of seed. or Hot water seed treatment (52 C for 10 min) to lower the infestation.
