Étude de l’efficacité qualitative et quantitative du curetage à court et moyen terme

Abstract : Grapevine trunk diseases, including Esca, cause the death of vines. They have been on rise in France since the ban on sodium arsenite in 2001. Since then, none effective solution has been proposed to winegrowers for this crisis which cause serious economic consequences. Grapevine surgery is a curative technique against Esca. It consists in removing infected parts of the trunk. The study seeks to quantify at short and medium term effectiveness of this operation. In comparison with healthy and diseased vines, grapevine surgery stabilizes the condition of operated vines. At medium term, they regain the same behaviour as healthy vine in terms of physiology and berry quality. They are therefore resilient. For a plot under high pressure from Esca, half of the vines operated on would be resilient and only 13% of them would have died after five years.
