The continuous use of copper-based products in the vineyards has increased the copper content into soils, becoming an increasing problem for the environment. It currently exists restrictions on the total amount of copper allowed to be applied in the soils, and further restrictions are expected in the near future.
In the current phytosanitary market, newly developed formulations are available as alternatives to replace or reduce the use of copper-based products. Some examples are the biocontrol and biostimulants products. The main objective of this activity is to test different strategies in different disease pressure scenarios, climatic conditions, and locations to assess the best strategy to control fungal diseases while ensuring good management of the wines and the environment.
After the accomplishment of the activity, growers will have knowledge about the most effective strategies to be applied against fungal diseases with alternative products with non-toxic compounds. Thus, it will be possible to reduce the annual dose of copper applied, and also to ensure harvest in terms of quality and quantity. Moreover, this knowledge will allow growers to accomplish with the European regulations and to guarantee sustainable practices with the environment.
