All we can do now is to try to prolong the life and ease the suffering and burden of the ailing mango tree. Delaying post-harvest ripening can also help manage anthracnose in mangos. Cultivars such as Langra, Totapuri, and Mallika are types more susceptible to infection. This is achieved via biologically active soil with adequate organic matter and nutrient cycling to balance the chemical, biological and physical condition of the soil.

Hundreds of mango cultivars are known worldwide. Poor Mango fruit set can be caused by poor pollination due to cold weather at flowering or fungal diseases, such as anthracnose in the flowers. Tender shoots and foliage are affected which ultimately cause “die back” of young branches. Other reasons for fruit falling off include water stress, poor pollination, disease and insect attack. Diseases affect in Mango fruit drop . Prune back into a healthy portion of wood. Control – Soil application of Heptachlor or Methyl Parathion at 25 to 30 kg/ha kills pupating larvae in the soil.
