Esca is a grapevine trunk disease (GTD) associated with different pathogenic fungi inhabiting the woody tissues. Bacteria can also be found in such tissues and they may interact these fungal colonizers. Although types of microbial interaction have been observed for wood diseases many trees, this has never studied grapevine. In study, bacterial microflora vine status (esca-symptomatic asymptomatic), anatomical part (trunk cordon) type (necrotic or not) studied. Based on Single Strand...
Abstract Grapevine trunk diseases cause yield losses and vine mortality in vineyards worldwide. However, there have been few quantitative studies evaluating grapevine dieback on a large spatial temporal scale. Here, we consolidated standardized databases from the 13 main wine regions of France, compiling records leaf symptoms associated with esca Eutypa 2082 plots 36 cultivars over 20‐year period. This dataset was used (a) for analysis prevalence (number at least one symptomatic plant)...
Grapevine decline, a major global viticulture issue, is defined as multi-year decrease in vine productivity and/or increase mortality. Although grapevine trunk diseases are one of the most-studied causes, decline multifactorial and associated with more than 70 factors, including abiotic biotic hazards. With so many factors to consider, phenomenon difficult understand, especially for winegrowers. Our study aims make it easier determine assess by focusing on three key indicators: yield,...
Afin d’étudier la sensibilité variétale à l’esca, nous avons récemment analysé les incidences annuelles de symptômes foliaires issues d’une parcelle expérimentale (2017–2023) (Gastou et al., 2024) d’un réseau surveillance des maladies du bois en France (2003–2023) (Etienne 2024). Ces travaux ont permis confirmer variabilité très importante d’incidence d’esca entre cépages, que ce soit dans régions viticoles françaises ou au sein même parcelle, ouvrant discussion sur facteurs l’origine cette...
