Symptoms:

• The developing young leaves show a white powdery mass causing them to shrink and defoliate.
• Small, white powdery growth appear on the young fruits which later enlarge and coalesce and final turn brown to dark brown.
• In severe cases, the whole fruit surface gets covered with the powdery mass.
• Affected young fruits drop off prematurely or become corky, cracked, mis-shapen and underdeveloped.
• Matured fruits turn rusty. Sometimes the whole crop is rendered unmarketable.

Management:

• Spraying of dinocap 0.05 per cent or wettable sulphur 0.25 per cent should be done during first and third weeks of November or when the fruit attains pea size.
• Triton-AE or Teepol or Sandovit may be added for adhesion.
