It is likely that the fruits of soursop are being attacked by fruit borer (Cerconota anonella). Through the wound caused by pest attack the soursop pulp, fungi and bacteria lodge in the fruit, making it unfit for consumption and marketing. As a control method, do a cleanup by removing the plant graviolas that were damaged and then destroy them. It is recommended the application of a crop protection product, however, to recommend the most suitable product for the treatment, the suggestion is to contact an agronomist or technical area, professionals may also give a better diagnosis of the causes responsible for damage the fruit.
