Molecular detection of Neonectria galligena (syn. Nectria galligena)
Mycological Research, 2002A pair of primers specific for Neonectria galligena were designed from comparisons of the internal transcribed spacer (ITS) regions 1 and 2 of 32 isolates of diverse origins with sequences from 7 other nectriaceous species: ‘Nectria’ ditissima, N. coccinea, N. coccinea var. faginata, N. punicea, N. fuckeliana, N. cinnabarina , and N. radicicola.

Degradation of benzoic acid by Nectria galligena Bres. in vitro and in vivo
Physiological Plant Pathology, 1973Abstract The concentration of benzoic acid in the diseased area of immature Bramley's Seedling apple fruits inoculated with Nectria galligena decreased as the arrested lesions expanded into progressive rots, and none was detected in natural canker rots. Benzoic acid was not degraded in healthy apple tissue, even after prolonged incubation.

Mycologia, 1975
Conidia of Nectria galligena Bres. are the important infective propagules in the epidemiology of European apple canker in California. However, little is known about the effects of temperature and relative humidity on conidial germination and survival. Various authors (2, 3, 5) indicate that conidia are strictly water-dispersed and that several hours of

The control of apple canker (Nectria galligena) in a young orchard with established infections
Annals of Applied Biology, 1975SUMMARYIn a factorial experiment on canker control the efficiency of phenylmercurie nitrate (PMN) applied at leaf fall, before bud burst or both was compared with the application of dodine, dithianon, triforine, thiabendazole, benomyl or carbendazim in May and June.

Biochemical Changes in Cultures of Nectria galligena during the Autolytic Phase of Growth
Annals of Botany, 1970Some biochemical changes occurring in cultures of Nectria galligena during its autolytic phase of growth have been investigated. In nitrate-grown and autolysed cultures of this fungus the degree of autolysis amounted to 57 per cent. The amount of mycelial lipids decreased continuously with the age of the culture.

The biosynthesis of benzoic acid in Bramley's Seedling apples infected by Nectria galligena Bres
Physiological Plant Pathology, 1975Abstract Radioactive benzoic acid was synthesized from glucose-14C and l -phenylalanine-14C in apples infected with Nectria galligena and in apples infused with protease extracted from tissue rotted by N. galligena. Phenylalanine ammonia-lyase (PAL) activity was rapidly induced in apples infused with the fungal protease but a lag phase occurred ...

Biocontrol ofNectria galligenainfection of pruning wounds on apple shoots
Journal of Horticultural Science, 1979SummaryThe antagonism of micro-organisms towards Nectria galligena in vitro showed poor correlation with their field performance as wound protectants. Inoculating pruning cuts with micro-organisms prior to infection by N. galligena gave protection equivalent to that obtained with benomyl, but with marked reductions in lesion length and spore output.

Rotting of Apples of the Variety ‘Bramley's Seedling’ by Nectria galligena, Bres.
Nature, 1964THE first records of fruit rotting by N. galligena were made by Salmon and Wormald in Kent1 and Dillon-Weston in the Wisbech area2, where it occurred on the variety ‘Worcester Pearmain’; it has since been reported as troublesome on a number of dessert varieties in various European countries3–6.

Microflora of apple leaf scars in relation to infection by Nectria galligena
Transactions of the British Mycological Society, 1973The fungi present within the senescent tissue of Bramley's Seedling apple leaf scars were isolated and identified. Within a few weeks of leaf fall most scars were colonized by fungi. The most frequent species were host-specific organisms, such as Phoma limitata, Fusarium lateritium and Phomopsis mali and common saprophytes, notably Aureobasidium ...
