Ecoviti Sud-Ouest : Performances de systèmes viticoles innovants à faible niveau d’intrants phytopharmaceutiques sur le bassin de production Sud-Ouest.
Year: 2019
Type: article
Abstract: ECOVITI Sud-Ouest is setting up three innovative low-input wine-growing systems on two experimental platforms in the production area of Gers (IGP Côtes de Gascogne) and Tarn (AOP Gaillac and Côtes du Tarn). IGP systems are based on a high level of mechanization that can generate significant production and accept a certain level of loss. The AOP system is conducted in organic viticulture and is based on a drastic reduction of copper doses. After stabilization of the 3 systems, four years of results show a strong reduction of Treatment Frequency Index (TFI) by more than 65% of the local reference. Mildew is the most difficult disease to control. On 2 prototypes it generates significant yield reduction which affect the economic profitability of the system, even if grape quality objectives are achieved. At the end of the study, one prototype reaches all the objectives, validating the decision rules adopted.
