Mango tree problems: withered blackened young growth indicates the presence of tip borers. Spray with a systemic insecticide e.g. Rogor (full protection when spraying) and be sure to coat both sides of the leaves.
Anthracnose fungus causes black spotting on the leaves, flowers and fruit. Spray regularly (flowering to harvest) with Mancozeb. Root fungus or collar rot may be terminal but try a systemic fungicide e.g. Phosacid. Coat both sides of leaves. Do not water mango trees in the 3 months or so prior to flowering.
