• Seeds may develop raised or sunken lesions and become shriveled and discolored.
• Small, angular, translucent, water-soaked, yellow to light brown spots appear on leaves.
• Young leaves are most infected and are destroyed, stunted and chlorotic.
• Angular lesions enlarge and merge to produce large, irregular dead areas.
• Early defoliation of lower leaves may occur.
• Large, black lesions develop on stems and petioles.

Management

• Deep summer poughing.
• Use healthy/certified seeds.
• Destroy infected crop debris
• Seed treatment with streptocyclin @ 250 ppm (2.5 g/10 kg seeds).
• Application of any copper fungicides @ 2 g/lit along with streptocyclin at the rate of 250 ppm (2.5 g/10 lit water).
