Oidium mangiferae

Oidium mangiferae is a species of fungal organism that belongs to the Erysiphales order. It is commonly known as the mango powdery mildew and is a significant plant pathogen that primarily affects mango trees.

Taxonomy

The Oidium mangiferae was first described by Berkeley and Curtis in 1869. It belongs to the Oidium genus, which comprises various species of fungi that cause powdery mildew in plants. The Oidium genus is part of the Erysiphaceae family, within the Erysiphales order.

Description

Oidium mangiferae is characterized by its white to grayish powdery growth on the surface of mango leaves, flowers, and fruits. The fungus produces conidia that are hyaline, cylindrical, and produced singly. The mycelium is superficial, producing conidiophores that are unbranched and erect.

Distribution and habitat

Oidium mangiferae is widely distributed in regions where mango trees are cultivated. It thrives in warm, dry climates and is particularly prevalent in India, Pakistan, Florida, and the Philippines.

Pathogenicity

As a plant pathogen, Oidium mangiferae causes significant damage to mango crops. The disease it causes, known as mango powdery mildew, is characterized by a white to grayish powdery growth on the surface of leaves, flowers, and fruits. Infected mango trees exhibit reduced vigor, yield, and fruit quality.

Management

Management of Oidium mangiferae involves a combination of cultural practices and chemical control. Cultural practices include pruning and sanitation to reduce the source of inoculum. Chemical control involves the use of fungicides such as sulfur and triazole.
