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 ...

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 (

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

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.

Annual Rhythms of Ascospore Discharge by Neonectria ditissima in Northern Germany and Norway
Applied Fruit ScienceAscospore release by the European apple canker fungus Neonectria ditissima was examined by means of continuously running spore traps mounted over detached segments of apple tree branches with cankers habouring maturing and ripe perithecia, or placed within tree rows in apple orchards. Records began in autumn 2017 and continued for nearly 3 years at two

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.

Neonectria ditissima is the fungal cause of costly European Canker (EC) in apple trees. A range of secondary metabolites were found at higher concentrations in infected twigs than in disease free twigs. Apple trees were then experimentally inoculated with N.
