Neonectria ditissima physiological traits and susceptibility of ‘Gala’ and ‘Eva’ detached apple fruit

Tropical Plant Pathology, 2020
European Canker and Neonectria fruit rot (NFR), caused by Neonectria ditissima, has become a major problem for the production of apples (Malus domestica) in Brazil. This study characterized environmental factors affecting in vitro growth and germination of Neonectria ditissima as well as infection, colonization and reproduction, ex vivo, on ‘Gala’ and ‘

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,

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.

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 ...

Resolving the status ofNeonectria ditissimain South Africa

Australasian Plant Pathology, 2010
Fruit 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,

Real-time PCR for detection and quantification, and histological characterization of Neonectria ditissima in apple trees

Trees - Structure and Function, 2016
Key message We designed a pair of primers from a region of the β-tubulin gene to detect and quantifyNeonectria ditissimain wood of some infected apple cultivars, and optimized light microscopy to study fungal-plant interactions.

Isolation and characterization of codominant markers for the perennial canker fungal pathogen Neonectria ditissima

Molecular Ecology Resources, 2009
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.

Temporal Dynamics of Neonectria ditissima Spore Release From Whole and Shredded Branches of ‘Gala’ and ‘Fuji’ Apple Cultivars

Journal of Phytopathology
European canker (EC), caused by Neonectria ditissima , is one of the major threats to apple production in temperate and subtropical highland regions, where pruning residues represent an important source of inoculum.

Organic and inorganic nitrogen effects on spore production and mycelial growth of Neonectria ditissima in vitro

New Zealand Plant Protection, 2018
Nitrogen (N) is known to influence the growth of Neonectria ditissima (N.d.), the causal organism of European canker. In vitro, inorganic N inhibits conidia germination at N concentrations above 0.2 mol/L while, in planta, foliar urea application increased disease expression of leaf scar wounds up to nine-fold.
