Podosphaera leucotricha (Ellis & Everh.) E.S. Salmon 1900

Cunningham (1925a) and Woodhead (1959) stated that powdery mildew on apples is one of the most serious diseases with which a grower has to contend. It occurs in all apple-growing areas in New Zealand. They list `Jonathan', 'Cox's Orange', 'Gravenstein', `Stunner Pippin', `Lord Wolseley', `Dunn's Favourite', and 'Cleopatra' as susceptible varieties. Systematic culling out of infected shoots and buds during the winter pruning combined with a suitable spray schedule is recommended for its control. Woodhead (1959) stated that colloidal sulphur used with lime sulphur has greatly improved the control of the disease and has reduced the spray damage to fruit. Geldermalsen (1963) showed that an intensive programme of sulphur sprays gave the best control, especially when applied for two successive seasons.

Podosphaera leucotricha (Ellis & Everh.) E.S. Salmon 1900

Type: Powdery Mildews; Description: Mycelium superficial, moderately dense to dense, white, hyphae 3–5 μm wide; on leaves, twigs, and fruit. Appressoria not lobed. Ascomata cleistothecial, gregarious, superficial, globose, black, 0.1 mm in diameter, with 5–6, 230–420 μm long, unbranched, hyaline apical appendages. Asci one per ascoma, oval, 90 × 60 μm. Ascospores 8 per ascus, 0-septate, 25–30 × 12–15 μm, smooth, hyaline. Conidio-phores 75–115 × 9–10 μm, foot cell swollen at the base. Conidia produced in long chains, oval, 0-septate, 27–30 × 17–18 μm, smooth, hyaline.
Distribution: Auckland, Wellington, Gisborne, Nelson, North Canterbury, Mid Canterbury, Central Otago, Dunedin.; 1st Record: Kirk (1901: as powdery mildew on apple).
Significance: Powdery mildew of apple is a disease of major importance. Heavy infection can reduce yields significantly (Atkinson 1971).; Host(s): *Malus ×domestica, Photinia serrulata, Pyrus communis, P. pyrifolia.
