[5] It is also found in Mexico, Martinique, Cameroon, South Africa and in the French West Indies (Gustafson, 1976;[6] Willis and Mavuso, 2007;[7] Everett and Siebert, 2018).

In South Africa, black spots on the leaves causing crop losses of up to 69% have been reported, in fruits used for export from orchards planted in a highly susceptible cultivar without suitable disease management (Darvas et al., 1987;[9] Crous and Braun, 2003).

As the disease progresses, the spots on the fruit begin to sink (into the skin), forming cracks without causing internal damage (Darvas, 1982;[13] Dann et al., 2013).

[14] These cracks, become target entry points for other pathogens, such as fungi (e.g., Colletotrichum gloeosporioides) that cause anthracnose (cankers) (Tamayo, 2004).

[9] Usually, the fungus can remain dormant in the leaves for a period of about three months, becoming a source of inoculum for the infection of new fruits (Darvas, 1982).
