The continuous processing of the land and the continuous application of pesticide and fertilizer, as well as the use of heavy machinery, often causes soil erosion, problems at the level of organic substance in soil, and contamination in the Mediterranean vineyards. On the other hand there is climate change with a reduction in summer rainfall and an increase in temperatures. This leads to water stress and an unbalanced maturation. The solution to those problems must be in harmony with sustainable viticulture that uses techniques and products that can also be applied for a biological management of the vineyard.
The research of Eleonora Cataldo from the University of Florence is linked to the Life Zeowine project, and aims to evaluate the reduction of water stress, improve the quantitative performance of the vines and improve the quality standard. The project was carried out in Tuscany, among the three different treatments a promising product based on the combination of Zeolite and Compost which gave the best results.
Being that the new regulation for organic viticulture requires a significant reduction in copper-based treatments in the vineyard, in which the maximum allowed is 28 kg / ha in 7 years, in the following two videos we offer presentations related to other effective strategies.
William Antonio Petrucci of CREA-VI created a possible strategy to minimize the number of copper applications in the vineyard, thanks to the Life Green Grapes project, based on the use of so-called "support substances".
The purpose of Giovanni Mian's work, a researcher at the University of Udine, is to determine the possibility of optimizing the effectiveness of copper treatments for low impact viticulture, using and evaluating the variation of copper coating on the leaves and on the grapes on the vine, in relation to the climatic conditions.
