Fungal Disease

This disease is favored by high humidity and tends to occur on older leaves first. Symptoms first appear as white powdery residue primarily on the upper leaf surface. On the lower surface of the leaves circular patches or spots appear. In severe cases, these spread, coalesce and cover both the surfaces of the leaves and spread also to the petioles, stem, etc. Severely attacked leaves become brown and shrivelled and defoliation may occur. Fruits of the affected plants do not develop fully and remain small.
