Plant Pathology, Volume 72, Issue 3, Page 521-535, April 2023., 2023 Narrow xylem vessel diameters are important to the resistance of some olive cultivars to Xylella fastidiosa. Successful screening protocols to identify resistant plants should therefore include a xylem morphological analysis. Abstract Xylella fastidiosa is a xylem‐limited plant pathogen infecting many crops globally and is the cause of the recent olive

Xylotrechus arvicola (Coleoptera: Cerambycidae) capture in vineyards in relation to climatic factors
Pest Management Science, Volume 78, Issue 7, Page 3030-3038, July 2022., 2022 This study demonstrated that capture periods of Xylotrechus arvicola in vineyards spanned from 1 June and 31 July, with the period from 1 to 30 June having the greatest number of insect captures, as long as weather conditions were favourable (temperature above 20.00 °C and accumulated rainfall in 10 days lower than 0.40 mm).

Development of an isolate-specific marker for tracking Phaeomoniella chlamydospora infection in grapevines [PDF]
Mycologia, 2005 Petri disease causes decline of grapevines worldwide. The grapevine endophyte Phaeomoniella chlamydospora is the most important fungal pathogen associated with this disease. Epidemiological studies of this pathogen have been hampered by its common occurrence in the internal tissue of apparently healthy vines.

EFSA Journal, Volume 20, Issue 1, January 2022., 2022 Abstract The qualified presumption of safety (QPS) approach was developed to provide a generic pre‐evaluation of the safety of biological agents. The QPS approach is based on an assessment of published data for each agent, with respect to its taxonomic identity, the body of relevant knowledge and safety concerns.

Environmental Microbiology, Volume 23, Issue 10, Page 6104-6121, October 2021., 2021 Summary Fungi are considered to cause grapevine trunk diseases such as esca that result in wood degradation. For instance, the basidiomycete Fomitiporia mediterranea (Fmed) is overabundant in white rot, a key type of wood‐necrosis associated with esca. However, many bacteria colonize the grapevine wood too, including the white rot.

How Iron Could Be Involved in Esca Fungi Development
Phytopathologia Mediterranea, 2001 Iron reduction capability was detected by ferrozine assay in Phaeomoniella chlamydospora, Phaeacremonium aleophilum and Fomitiporia punctata. On the other hand, the Chrome Azurol S (CAS) assay demonstrated that low molecular weight chelator agents were ...
