It is caused by Phoma sp. i.e., Phomopsis phyllanthi, Nigrospora sphearica, Cladosporium tenuissium, Pestalotia creenta, Alternaria alternata, Cytospora sp. The disease appears as small, pinkish brown necrotic spots. Smoke brown to black round lesions, black ring spots or colourless soft areas appear resulting in partial or complete rotting of fruit.
It can be managed by giving post-harvest treatment to the fruit with difolaton @ 1.5 g/l of water or mancozeb @ 1 g/l of water or carbendazim @ 0.5 g/l of water.
