Today, agriculture faces organizational, societal, and climatic challenges that directly affect winegrowers. One key priority unites us: preserving our resources. To support sustainable viticulture and develop long-term solutions for Provençal wines, four partners launched the MYCOVIGNE project.
Mycophyto, Crédit Agricole, the Centre du Rosé, and Château Sainte Roseline are testing the benefits of controlled mycorrhization in Arcs-sur-Argens. This innovative approach combines expertise in soil biodiversity, vineyard experimentation, financial support, and the ideal vineyard site at Château Sainte Roseline.
In 2021, 100 vines were mycorrhized. Micro-fungi, multiplied in the lab, were introduced into the soil, and the vines have since been compared with 100 untreated vines nearby. In 2022, despite 40% less rainfall than the four-year average, the mycorrhized vines showed 20% less water stress and a 45% higher grape yield per vine.
The MYCOVIGNE project aims to address major challenges: reducing inputs, enhancing vine resilience, refining wine quality, and easing vineyard labor. Château Sainte Roseline is proud to contribute to this ambitious initiative, fully aligned with its CSR commitments.
