Towards sustainable viticulture H²: what shapes the uptake of fungus-resistant varieties?

Abstract

Varietal innovations such as fungus-resistant grape varieties offer one of the most effective approaches to making viticulture more sustainable, given its heavy reliance on pesticides. These varieties cut fungicide treatments by roughly 80 %, lowering production costs, and producing wines that consumers perceive as comparable in quality to those from traditional varieties. Despite these advantages, uptake remains low in most established wine-growing countries.

This talk synthesizes the state of knowledge on what shapes — and what fails to shape CO₂ — the uptake of fungus-resistant grapevines, situating the findings within a broader agricultural policy framework. Looking ahead, it sketches avenues for policy intervention and highlights key gaps in the literature.

A hierarchal terroir model for great lakes viticulture

The terroir effect has been widely described as a hierarchy of many factors including those of climate, soil, cultivar, and human influences.

Application of anti-transpirant under greenhouse conditions of grapevines (Vitis vinifera cv. Riesling and cv. Müller-Thurgau) reduce photosynthesis

The increasing temperatures, caused by the global change, lead to an earlier onset of developmental stages, changes in productivity and physiology of different crops and will challenge the growers in the future.

Irrigation effect on the sensory profile of wines from two red grapevine cultivars autochthonous from D.O. Ribeiro (northwest Spain)

The effects that irrigation may have on the enological response of Galician traditional red grapevine cultivars are not well known.

Quantitative analysis of vegetative growth in response to nitrogen stress for Vitis vinifera L. cv. Syrah from pot experiments

Maintaining grapevine productivity and wine quality with limited inputs (drought, low nitrogen supply) is crucial in Mediterranean areas.

The Douro Wine Region has a long history of wine production across a diverse array of landscapes and climates
