Mise en oeuvre et évaluation d’outils appliqués à la réduction de l’utilisation de fongicides sur le vignoble d’approvisionnement de la Maison Louis Latour Ardèche

Abstract : Nowadays politics, people and environmentalists would like agriculture to reduce its uses of pesticides because they have doubts on their harmlessness for people and environment. Vitis vinifera are sensitive to two main diseases, powdery mildew and downy mildew, that have been imported from the US during the XIX century. To protect the quality of thre grapes and to avoid yield losses winegrower must spray their vineyard several times a year. Recently several tools have been designed to help winegrower in reducing the use of pesticides and few of them have been challenged on Louis Latour’s vineyard in diferent experiments. Optidose adjusts the quantity of pesticide considering the vine leaf volume, the epidemic of the diseases and the sensitivity of the plants. It gives good results in protecting the vineyard and also in reducing the use of pesticides. Decitrait is an other tool that has been tested. Using the meteo data it predicts when the contaminations can happen. The predictions made were good and the tool seems to be efective. More and more supports are available to help winegrower in enhancing the way they produce. Their evaluations are conclusive and show good results in terms of crop protection and to reduce the use of pesticides.
