Utilization of resistance mechanisms of diverse vine species for substituting copper applications in ecological vineyards
Description:
Module 1: Extracts from wild vine respectively highly resistant hybrids. It has to be investigated if leaf extracts gained from non-Vitis-vinifera species and applicated on quality vine species are able to fight and suppress Plasmopara viticola and other diseases or if plant´s own defence mechanism can be activated by elicitors from the extracts. Module 2: Possible reduction of copper use in fungi resistant cultivars of Vitis vinifera. The cultivation of fungi-resistant species enables an abandonment of plant protection to a large extent and is ecologically and economically the most sustainable form of viticulture. The potential of copper savings due to fungi-resistant cultivars is probably depending on the resistance of the cultivar itself as well as on regional climatic conditions. In this study the necessary dose of plant protection will be investigated for the first time. An experimental plot with a specific overhead irrigation system was established in 2009. Here, introductory experiments simulating different levels of infection pressure will be conducted based on a variety of vines showing pyramidized resistance against Plasmopara.
