Diseases of Fruit Plantation Medicinal and Aromatic Crops

Aspergillus rot

Causal organism: Aspergillus niger
SYMPTOMS
The rot may be mostly internal. Masses of black powdery spores are observed only when the fruits are cut open. But much soft, sunken, water soaked spots may develop on the skin that later gives rise to black spores resembling “soot”. The decay is accompanied by fermentation odour. Infection is observed when fruits are still on the tree but they look externally healthy.
