Diseases of perennial crops such as mango are devastating due to the long time period to maturity for the plants, as a tree grown from seed will not produce fruit until it has reached three to six years of age. In contrast, the mango tree may live and produce fruit for several hundred years if it remains healthy and is well cared for. [10]
Few of the symptoms can be mistakenly confused with insect injury or infection from other disease like mango anthracnose. [3] [4] Confirmation of the presence of mango scab requires microscopic examination of material from fruit, stems or leaves, and culture of the organism. Culture will only be successful from lesions on young plant material.

Phoma blight Phoma glomerata. Phyllosticta leaf spot Phyllosticta mortonii Phyllosticta citricarpa Guignardia citricarpa [teleomorph] Phyllosticta anacardiacearum
There are a range of cultural, chemical and non-chemical techniques for minimizing damage to the mango crop, for example the use of physical barriers to stop Drosicha mangiferae nymphs crawling up the stem of mango trees, by wrapping plastic sheets or sticky bands (sometimes impregnated with insecticide) around the tree stem.
