Mango Malformation Disease is a fungal disease of mangoes caused by several species of Fusarium, some yet to be described. Mango is only known host of the disease.
The disease spreads on a tree very slowly, but if left unchecked, can severely reduce yields. The main method of spreading MMD to new areas is through infected vegetative planting material. There is no evidence that the disease can spread on fruit or the seeds, or that it affects

Mango Malformation Disease has been found on most mango growing countries of the world. Australia was thought to be free of the disease but in November 2007, symptoms of MMD were detected on treed in a finalized research trial containing about 2,000 trees at Coastal Plains Research Farm at Middle Point.
