The mango fruit is susceptible tomany postharvest diseases caused by anthracnose (C. gloeosporioides) and stem end rot (L. theobromae) during storage under ambient conditions or even at low temperature. The host gene response in mango fruit against C. Anthracnose is a major pre and post harvest disease on mango, causing direct yield loss in the field and packing plant, and quality and marketing issues thereafter. Anthracnose is a general term for a variety of diseases that affect plants in similar ways. In the field, anthracnose can cause a direct loss of fruit and, if left untreated in harvested fruit, the blemishes it produces can make mangos hard to market.

All commercial mango operations in humid climates require regular fungicide spray applications to protect against anthracnose, a destructive disease that can severely reduce fruit production. Glomerella cingulata (it also has the name of Colletotrichum gloeosporioides). anthracnose to some of the registered fungicides, a laboratory study was conducted. Anthracnose can manifest itself on leaves and petioles, but it is mainly a fruit disease. However, paucity of genomic information has hindered our understanding of the molecular mechanisms underlying the mango fruit defense response to anthracnose and its effective management. Tree anthracnose is caused by a fungal infection fueled by optimal weather conditions. Indigenous to India and Southeast Asia, trees are particularly susceptible to two diseases of mango: anthracnose and powdery mildew. Once identified, tree anthracnose should be treated immediately. A review of the etiology and epidemiology of the disease is provided below as background for the various approaches that have been used to manage the disease.
