Dormouse injuries predispose beech to infection byNeonectria ditissima
Forest Pathology, 2011SummaryAfter awaking from winter hibernation, the Edible dormouse begins to feed by stripping the bark and the outer part of the xylem from the branches of both broadleaves and conifers. Natural or artificial wounds are essential for the penetration and colonisation of the tissues by the fungal pathogenNeonectria ditissima.

Viability and release of Neonectria ditissima ascospores on apple fruit in Brazil
Plant Pathology, 2021Abstract During European canker monitoring in an apple experimental orchard, 14 mummified fruit (two and three trees with 10 and four positive records in 2018 and 2019, respectively) showed perithecia. Perithecium production on apple fruit, confirmation of pathogenicity of Neonectria ditissima

Neonectria ditissima, the causal agent of European Canker and Neonectria fruit rot, is a quarantine apple pathogen in Brazil, restricted to some production areas of Rio Grande do Sul, Santa Catarina, and Parana states. The quarantine rests on a product certification based on the absence of symptoms but it is not known whether the pathogen could be ...

Approaches for evaluation of resistance to European canker (Neonectria ditissima) in apple
Acta Horticulturae, 2016European canker is caused by the fungus Neonectria ditissima (Neonectria galligena, formerly Nectria galligena). The disease causes significant losses to apple production in Sweden and many other countries with a temperate wet climate. Application of fungicides and good horticultural practices do not prevent canker damage in nurseries and orchards ...

Development of Neonectria ditissima infections initiated at grafting of apple trees
European Journal of Plant Pathology, 2019Infections of Neonectria ditissima, the cause of European fruit tree canker, may be initiated during propagation. In a survey of 19 commercial apple orchards in southern Norway in the year of planting or the following year, the graft-union area of 15,270 trees was examined. The disease was found in 53% of the orchards, at a low incidence (

Resolving the status ofNeonectria ditissimain South Africa
Australasian Plant Pathology, 2010Fruit pathogens are currently one of the main factors involved in quarantine-related market access. Unconfirmed South African records pertaining to the presence of the causative agent of European canker of apples, Neonectria ditissima, have been the cause of many disputes regarding its status as a quarantine pest in this country. To clarify this issue,

Abstract Neonectria ditissima is a fungal pathogen native to eastern North America that causes disfiguring cankers on numerous tree species, particularly birches (Betula spp.). In order to develop control strategies, fundamental knowledge of the pathogen's reproductive and dispersal dynamics is necessary.

Current control strategies for the major apple disease European canker (EC) are laborious and expensive, and often do not prevent progression of the disease, which can lead to loss of trees and therefore production. Hence, the development of resistant cultivars is a significant goal for breeders supporting growers in maritime climates conducive to the ...
