Detection and characterization of quiescent infections of Neonectria ditissima in Brazilian commercial apple fruit

Tropical Plant Pathology, 2021
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 ...

Resistance to Neonectria ditissima in apple: insights from metabolomics and lipidomics analyses

Acta Horticulturae, 2023
European canker, caused by the necrotrophic fungus Neonectria ditissima, is the most serious disease in apple production in Sweden. The disease is favored by a relatively cool and rainy climate. The canker damages have a significant economic impact due to reduced bearing surface and increased orchard management costs. The possibilities for chemical and

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 (

Sensing Disease in Apple Trees: Potential Signature Compounds for European Canker (Neonectria ditissima) Infection.

Journal of Agricultural and Food Chemistry
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.

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 ...
