Major diseases of mango

which may be controlled by periodic fungicide applications from bloom to harvest, powdery

mildew (Oidium sp.) which may be controlled by 1 to 2 fungicide applications during bloom,

and mango scab (Elsinoe mangiferae) which may be controlled by periodic fungicide sprays

during fruit set and early fruit development?

Mango malformation is caused by Fusarium subglutinans (syn. F. moniliforme var. subglu-

tinans) and is spread mechanically (grafting) and infected nursery stock. Spread within and

among trees not well understood.

materials, and scout/monitor grove continuously.

Disorders of mango – Mango decline and Internal breakdown

Mango decline appears to be a complex and research to date suggests this is caused in part

(Botryosphaeria ribis and Physalospora sp. and others). Symptoms include interveinal chlorosis,
