Flavonoids and phenolic acids play roles in grapevine defence against pathogens causing trunk diseases (GTDs). Rutin is a major flavonoid vegetative organs of the grapevines, this compound, unlike other flavonoids, non-toxic non-oxidizable. was assayed vitro vivo two Botryosphaeriaceae taxa. The limited bioavailability compound circumvented by conjugation with stevioside, glycoside obtained fro...

The past fifty years important advances have been made in the field of grapevine virus research, including characterization of pathogens and control measurements. Still the occurrence of Grapevine fanleaf virus (GFLV), Arabis mosaic virus (ArMV), Tomato black ring virus (TBRV), Grapevine chrome mosaic virus (GCMV), Alfalfa mosaic virus (AMV), Grapevine Bulgarian latent virus (GBLV), Grapevine f...

Methyl salicylate (MeSA) is a plant metabolite that induces defence resistance and an odorous volatile compound presenting green nuances. This was shown to be present in wine samples, sometimes at concentrations above its olfactory detection threshold. MeSA localized grapes, particularly the skins stems, extracted during red vinification. It detected highest wines of several grape varieties, ma...

Grapevine trunk diseases affect 13 % of French vineyards and esca has become more prevalent in recent decades (Grosman & Doublet 2012). Fussler et al. (2008) reported that an average 3.25 vines are affected by esca. Management these vines, considered unproductive, often consists cutting off the symptomatic arm or uprooting vine.
