Viability and release of Neonectria ditissima ascospores on apple fruit in Brazil

Plant Pathology, 2021
Abstract 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

Development of Neonectria ditissima infections initiated at grafting of apple trees

European Journal of Plant Pathology, 2019
Infections 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 (

Genetic mapping of the European canker (Neonectria ditissima) resistance locus Rnd1 from Malus ‘Robusta 5’

Tree Genetics & Genomes, 2019
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 ...

Dormouse injuries predispose beech to infection byNeonectria ditissima

Forest Pathology, 2011
SummaryAfter 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.

SCREENING OF APPLE CULTIVARS FOR RESISTANCE TO EUROPEAN CANKER, NEONECTRIA DITISSIMA

Acta Horticulturae, 2013
European canker, caused by the fungus Neonectria ditissima, is a severe problem in apple production both in Sweden and in many other northern European countries. Even when applying fungicides and good horticultural practices, canker damage occurs almost yearly in nurseries and orchards. Some years, devastating outbreaks destroy numerous trees. To date,

Apple endophyte community is shaped by tissue type, cultivar and site and has members with biocontrol potential against Neonectria ditissima

Journal of Applied Microbiology, 2020
This research aimed to identify factors influencing endophyte community structure in apple shoots and the bioactivity of cultured representatives against the fungal pathogen Neonectria ditissima.

Approaches for evaluation of resistance to European canker (Neonectria ditissima) in apple

Acta Horticulturae, 2016
European 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 ...

The use of rifampicin mutants and ERIC-PCR to track plant colonisation and in planta efficacy of bacterial biocontrol agents against Neonectria ditissima.

Journal of Applied Microbiology
AIMS Endophytic colonisation of apple shoots by bacterial endophytes with in vitro antagonism against Neonectria ditissima was evaluated. Their biocontrol activity against N. ditissima was assessed.
