Powdery Mildew (Oidium mangiferae) is a serious disease in mangoes in South Africa. Estimated losses are as high as 80%. Because outbreaks occur early in the flowering stage, damage is often underestimated. O. mangiferae only attacks mango plants. No other hosts have been found. The fungus attacks the inflorescences, leaves and fruit. Newly set fruitlets, when infected, drop when they reach pea-seize. It is exceptional for infected fruitlets to develop beyond marble-size and if they do, crakcs may develop or if the infection took place late in season, a web-like lesion may be seen on the mature fruit. Sepals of flowers are particularly susceptible; when flowers become infected, they fail to open and drop. Often the inflorescence is completely covered by mildew and the flowers drop while the remaining stalks become smokey grey and eventually black and necrotic. The most characteristic symptom of powdery mildew is a velvety, powdery appearance against a dark grey to smokey grey background. The ehite powdery appearance of infected tissues predominates in established lesions. |
