Nectria galligena Bres. 1901

Notes

After expressing considerable doubt about the occurrence of European canker in New Zealand, Cunningham (1925b) reported it from the Whangarei district. It has become extremely common in the Auckland apple-growing areas. Brook, P. J., and Bailey (1965) recommend for its control autumn and winter sprays with either phenyl mercuric chloride or Bordeaux mixture. It is of considerable economic importance in the Auckland area and has limited the planting of some susceptible varieties.

Neonectria galligena (Bres.) Rossman & Samuels 1999

Description

Type: Corticolous Fungi; Description: Ascomata perithecial, scattered or gregarious in groups of 3–4, globose to ovoid, bright red becoming dark red, finely warted, 0.1–0.4 mm in diameter, ostiole papillate and surrounded by slightly convex, smooth disc, superficial; on or associated with cankers on branches. Asci clavate, 60–100 × 10–15 cm. Ascospores elliptical to broadly oval, 1-septate, 14–22 × 5–9 em, smooth to slightly verrucose, hyaline. Macroconidia cylindrical, slightly curved, 3–5-septate, 20–65 × 3–6 lm, smooth, hyaline. Microconidia cylindrical, 0-septate, 4–8 × 2–3 m, smooth, hyaline.

Distribution

Distribution: Northland, Auckland, Coromandel, Waikato, Bay of Plenty, Taranaki, Gisborne, Hawkes Bay, Nelson, Westland.; 1st Record: Cunningham (1925b: as Nectria galligena).

Notes

Pathogenicity

Significance: A pathogen of apples (and occasionally pears), causing cankers on branches leading to dieback. The disease, known as ‘European canker’, is of considerable economic importance in the Auckland apple-growing area and has limited the growing of some susceptible varieties. It is not a major disease in other parts of the country (Atkinson 1971).; Host(s): Malus ×domestica, Pyrus communis, P. pyrifolia.
