Grapevine Trunk Diseases and Pruning Webinars

*Both webinars are only delivered in French*

Grapevine Trunk Diseases webinar

In order to better understand deterioration, Chloé Delmas and Giovanni Bortolami (Inrae from Bordeaux) worked on the characteristics of the vessels of the vine. In particular, they showed the role of the size of the vessels in the capacity of the vine to limit the progression of esca or to resist drought.

During this webinar, Chloé Delmas and Giovanni Bortolami answer questions posed by Thomas Chassaing from the Pays de la Loire chamber of agriculture. They then tackle the new avenues of research explored and explain in particular the link between the leaf symptoms of esca and the presence of occlusions in the vessels of the leaves.
