The disease has taken its toll and has become a limiting factor in mango cultivation in the region, taking a heavy toll on the trees. This year, the drought has caused huge losses for fruit growers and has led to total crop losses. In India, more than 1.5 million mangoes, or about a third of total mango production, have died.
In Pakistan, Aspergillus niger and Rhizopus nigrican have been reported as the cause of death for mangoes in the country, as well as E. erwinia, although the actual cause has not yet been confirmed.
The core drill is widely used in India and is certainly responsible for considerable damage. The damage is caused by the beetle, which feeds by drilling the stems upwards, drying out the branches. In severe cases, those who reach the trunk also die, but no information is available on the extent of the damage to the plant. This has become a limiting factor for mango cultivation in the region, affecting a variety of fruit trees, including mango, in various parts of India.

Mango scab (Elsinoe mangiferae) is an infection of the leaves and leaves of flowering fruits and branches. In severe cases, the infection destroys flowering panicles. And resulting in a lack of fruit set and defoliation of the mango trees. The eggs are laid in viscous fluid that covers the trunk and accumulates in the soil.
Ripe leaves that are infected behave like purplish spots – brown in color, and the leaves become distorted. The fruit lesions are covered with cork brown tissue and cause damage to the fruit.
Treatment of the fungus is a copper fungicide program that begins in early spring as the flowers develop and continue until the end of the harvest season. You can prevent the problem by planting in warm areas of the landscape, pruning the mangoes so that they have good air circulation and the fruits do not fall out.
Red rust, also called algae stains, is caused by the parasitic algae Cephaleuro spp. Mildew diseases caused by the fungus Oidium mangiferae can be a serious problem in mango cultivation areas.
The disease prefers cool, cloudy weather, but also occurs in warm, humid climates. Mature spores are easily blown away by the wind and produce a fresh infestation. But remain dormant and do not grow during the dormant phase of the unfavorable season in expectation of optimal germination conditions for the next season.
Eating and keeping mangoes healthy prevents phomas and helps to keep trees clean, remove fallen leaves and fruit. Avoid excessive branches and short branches, and prevent phomas. This treat infected trees with copper fungicide to ensure that the surface of the tree is covered. When spraying and cover all tree surfaces when spraying.
The relapse of mangoes can be a serious problem of mango. That severely affects the fruit and, in severe cases, can kill the entire tree.
The air fungus Lasiodiplodia theobromae attacks the tree and causes leaves, stems. And branches at the top to turn brown and die. Delicate shoots and foliage are affected. While young branches die and the disease results in a loss of fruit. And a reduction in the number of leaves and leaves per tree.
Old branches can also be infected with wounds that can be fatal in severe cases. Such as wounds to the head, neck, back, legs, arms or even the trunk.
