Pathogen survival: the pathogen survives between seasons on infected and defoliated branch terminals and mature leaves. This study did not identify any pathogenic or molecular features between isolates causing post-harvest anthracnose and those causing pre-harvest pepper spot symptoms. 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.

In order to improve the disease control with a limited use of fungicides, new microbial agents able to limit the growth of the pathogen were searched in the indigenous natural flora of mango surface. Glomerella cingu-lata (Ston.) Symptom and disease development: black, sunken, rapidly expanding lesions develop on affected organs Pathogen reproduction: sticky masses of conidia are produced in fruiting bodies (acervuli) on symptomatic tissue, especially during moist (rainy, humid) conditions. Ripe fruits affected by anthracnose develop sunken, prominent, dark brown to black decay spots before or after picking. The spots can expand and merge to cover the whole affected area.
