Papaya Anthracnose

Papaya anthracnose is caused by the flora Colletotrichum gloeosporioides and is one in every of the foremost widespread and devastating illness of papaya, particularly throughout storage. it's a serious constraint to papaya production furthermore on export of the fruit to larger overseas markets. Anthracnose infections are sometimes initiated within the field at early stages of fruit development, however the infectious agent remains quiescent till the fruit reaches the climacteric part. The flora is unfold by wind and rain whereas illness emergence is favoured by warm temperature and humidness. The illness will have a heavy impact on cold fruit for export. The Colletotrichum flora overwinters majorly in plant detritus and also the created spores rely on water for unfold and infection. they'll even be unfold by cultivating instrumentation or employees once the foliage is wet. The flora will penetrate the plant part directly and doesn't need natural openings e.g., stomata or wounds, and symptoms might seem at intervals 5-7 days once infection has taken place. illness development is favoured by heat, humid, and rainy weather sometimes frequent intervals. The flora will infect immature inexperienced fruits hooked up to the plant and stay quiescent till the fruit begins to ripen, once symptoms of anthracnose or chocolate spot seem.
