Descriptions
Uncinula necator (Schwein.) Burrill 1892
Type: Powdery Mildews; Description: Mycelium superficial, thin or dense, white, hyphae 5 μm wide; on leaves, stalks, and fruit. Appressoria multi-lobed. Ascomata not known in New Zealand. Conidiophores 70–100 × 5–8 μm when epiphyllous, 220–400 × 5–8 μm when hypophyllous, foot cell moderately to extremely flexuous at the base. Conidia produced singly, oval, 0-septate, 27–35 × 15–18 μm, smooth, hyaline.
Distribution: Auckland, Hawkes Bay, Mid Canterbury.; 1st Record: Kirk (1901).
Significance: Powdery mildew of grape is common in most main grape-growing areas, and can cause serious losses. Leaves are killed and early infection of berries checks their development, causing abscission. It is distinguishable from downy mildew by the presence of white powdery patches on the upper surfaces of leaves; the whitish glossy mycelial patches of downy mildew occur mostly on the undersides.; Host(s): Vitis vinifera.
