Protection of budding wounds in apple nursery trees from European canker

New Zealand Plant Protection, 2016
The fungus Neonectria ditissima can cause European canker in apple nursery trees In this study ten treatments of EMLA 9 rootstocks budded with Royal Gala were examined 5 Treatments included combinations of five budding tapes two budding methods and three fungicidal treatments Fifteen months after inoculation all Tbudded trees had died Chipbudded trees ...

Widespread distribution of kiwifruit bacterial canker caused by the European Pseudomonas syringae pv. actinidiae genotype in the main production areas of Portugal

Phytopathologia Mediterranea, 2012
In Portugal, in 2010, after the first recorded occurrence of Pseudomonas syringae pv. actinidiae (Psa) in a few kiwifruit orchards, and following subsequent records of suspected symptoms at the beginning of 2011, an extensive survey concerning Psa was ...

Reference genes for gene expression analysis in the fungal pathogen Neonectria ditissima and their use demonstrating expression up-regulation of candidate virulence genes.

PLoS ONE, 2020
European canker, caused by the necrotrophic fungal phytopathogen Neonectria ditissima, is one of the most damaging apple diseases worldwide. An understanding of the molecular basis of N. ditissima virulence is currently lacking.

Neonectria Canker Disease of Fir Caused by Neonectria neomacrospora in Austria

Plant Pathology, Volume 75, Issue 3, May–June 2026.
The fir pathogen Neonectria neomacrospora is first reported on 17 Austrian localities, causing dieback and mortality on Abies alba at cool‐moist sites. A growth experiment on agar presented optimum growth at ~20°C. Moreover, an inoculation experiment revealed higher mortality on A. concolor than A. alba, while Picea abies remained unaffected.

Adaptation of French Wheat Leaf Rust (Puccinia triticina) Populations to Triticale

Plant Pathology, Volume 75, Issue 3, May–June 2026.
Our results reveal significant genetic isolation between wheat and triticale Puccinia triticina populations. However, a few triticale‐derived isolates exhibit virulence profiles that are characteristic of bread wheat isolates, highlighting the need for integrated disease resistance management across both crops.

Pseudomonas syringae pv. actinidiae from recent outbreaks of kiwifruit bacterial canker belong to different clones that originated in China.

PLoS ONE, 2013
A recently emerged plant disease, bacterial canker of kiwifruit (Actinidia deliciosa and A. chinensis), is caused by Pseudomonas syringae pv. actinidiae (PSA). The disease was first reported in China and Japan in the 1980s. A severe outbreak of PSA began

Pest categorisation of Entoleuca mammata

EFSA Journal, 2017
Following a request from the European Commission, the EFSA Plant Health (PLH) Panel performed a pest categorisation of Entoleuca mammata, a well‐defined and distinguishable fungus of the family Xylariaceae native to North America.
