Small brown or black spots develop on the leaves, twigs, flowers, and fruit of the mango. The spots spread and many flowers may drop from tree before fruit develops, lessening the harvest. Ripe fruit develops sunken, darkened spots before or after harvest. Fruit may drop from the tree before ripening. Infected fruit may appear healthy when green, but develop symptoms after ripening.

You may also see “tear staining” on the fruit, or the development of deep cracks, giving the appearance of alligator skin.

Warm, humid, wet weather favors the development of anthracnose on mango.
