• The symptoms develop on the leaves and stem of seedlings or budded plants.
• On leaves, small water soaked lesions appear which later coalesce in the blighting of leaves.
• On stem, water soaked lesions develop initially and later turn to black colour.
• Stem infections develop any point on the stem causing the death of seedlings.

Management

• Remove and destroy the affected seedlings.
• Spray with 1 percent Bordeaux mixture or 0.2% copper oxychloride just before the onset of monsoon and thereafter at frequent intervals.
