Major Disease Of Mango And Their Management

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.
