Summer is the time you should start seeing developing mangos on your tree. A second symptom type on fruits consists of a “tear stain” symptom, in which are linear necrotic regions on the fruit that may or may not be associated with superficial cracking of the epidermis, lending an “alligator skin” effect and even causing fruits to develop wide, deep cracks in the epidermis that extend into the pulp. On Leaves Characteristic symptoms appear as oval or irregular vinaceous brown to deep brown spots of various sizes scattered all over the leaf surface, later forming elongated brown necrotic areas measuring 20-25 mm in diameter. Blight diseases in mangoes The two main diseases of mangoes are anthracnose and bacterial black spot. If the fruits don’t drop off before ripening, they have large dark spots that go beyond the surface and lead to rotting of the entire fruit. The causative fungi (usually Colletotrichum or Gloeosporium) characteristically produce spores in tiny, sunken, saucer-shaped fruiting bodies known as acervuli. Colletotrichum alienum, C. fructicola and C. karstii were only. Such fruit has no market value. The spots can expand and merge to cover the whole affected area.
