It all begins with the typical small spots that coalesce to larger lesions which then become dead areas on fruits, leaves and flowers. Cool, rainy weather creates perfect conditions for the spores to spread. isolates obtained from avocado and mango fruit showing anthracnose and pepper spot symptoms were screened for pathogenicity, comparative aggressiveness and cross-infection potential by inoculating onto detached avocado and mango fruit, avocado leaf petioles and branches of young, grafted nursery trees, as well as avocado fruit and pedicels still attached to the tree. In the field, anthracnose can cause a direct loss of fruit and, if left untreated in harvested fruit, the blemishes it produces can make mangos hard to market. Black mildew Meliola mangiferae .

Summer is the time you should start seeing developing mangos on your tree. 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. The mango population of the pathogen always predominated on mango, was not found on other tropical fruit crops, and had a restricted host range insofar as individuals from the population were highly virulent only on mango.” In other words, populations of the pathogen are essentially host-specific. The disease is often referred to as "anthracnose" of mango. This Agnote explains the diseases, causes, symptoms and the pesticide program for their control. Flower blight, fruit rot, and leaf spots are among the symptoms of this disease. Symptoms of damage of anthracnose on melon. Even minor disease like leaf spots can cause great losses. Anthracnose is a general term for a variety of diseases that affect plants in similar ways. When all isolates were grouped according to symptom or host of origin, significant differences in lesion severity were demonstrated between isolates on avocado petioles in the glasshouse, with avocado pepper spot isolates being the most aggressive, followed by avocado anthracnose isolates then mango isolates from both anthracnose and pepper spot, respectively. For breeding foliar resistance, I recommend saving your seeds from exposed plants every year to help acclimatize them to the pests/diseases (if they occur every year).
