As part of the EU project "RELACS", new plant protection products against powdery mildew and downy mildew were tested in viticulture. In their commercial vineyard in Frick, Switzerland, Research Institute of Organic Agriculture FiBL carried out 16 treatments of new plant protection products against mildew in organic viticulture. Three of the tested products used copper, the remaining 13 were replaced by pilot products, one of them based on larch extract.
To evaluate their effectiveness, FiBL interviewed managing vintner Andreas Tuchschmid who shared his practical experience with the new products. According to him, the products are effective, easy to apply, smell better and cause less irritation. On top of that, it prevented leaf burn, occasionally occurring when applying copper.
The video is available in German with English, French and Spanish subtitles.
