A Study on the Efficiency of Sustainable Wine Grape Vineyard Management Strategies

Crop protection strategies based on cupric products and mainly adopted in organic viticulture produce a consistent environmental impact due to the persistence of copper soils its negative effects edaphic biodiversity. In this work, trials were carried out during crop years 2018–2020 vineyard with an management by low-copper strategy conventional IPM reduced use fungicides. Phytosanitary treatments have been strictly planned according forecasting models, fungicides partially substituted substances improving resistance mechanisms plants. Different green manure management, order improve health vines, also adopted. Results suggest efficacy “GreenGrapes” plant conditions low downy mildew pressure. Furthermore, no declines production quality recorded; conversely, synergic effect tested biostimulant (“GreenGrapes” protocols) improved yield grape quality, compared conduction (IPM Organic) grass covering.
