Mango disease
Mango None Given
My mango tree bears plenty of mangoes, the fruit looks so nice and healthy but when it is time to have them, they are rotten inside. Some of the leaves have grey spots, many twigs and branches have thick white fungus like substance. Please help.

It sounds like you have multiple problems going on with your mango tree and you may have to practice better sanitation in the future.
-leaf spots: This is probably "gray leaf spot" of mango, which is common in neglected fields. Remove as many infected leaves/branches as possible and prune tree so there is better airflow and decreased leaf wetness. Most fungicides you spray for other pathogens will also eliminate this.
-white fungus-like substance: You don't find prolific fungal growth on twigs and branches of mango and other trees normally so this is probably a scale. The specific pest depends on your location. White mango scale is a problem in some regions and it's description could match what you have. If it is white mango scale then mineral oils and methidathion application are important to reduce populations.
