High eugenol content of Armagnac hybrid variety Baco Blanc, an asset in combating <i>Botrytis cinerea</i>

Abstract

Baco Blanc is the grape variety specific to the wine spirit Armagnac. A hybrid vine with good tolerance, particularly to Botrytis cinerea, its berries have an atypical chemical composition. Specifically, they have a high concentration of the anti-fungal compound eugenol. This research demonstrates the effectiveness of eugenol concentrations against B. cinerea and their relationship to the ripeness of Baco Blanc This study explores the intra-varietal diversity of B. cinerea tolerance, a potential source of adaptation to environmental and climate issues.
