In the degree thesis, we describe different managements for the control of downy mildew (Plasmopara viticola) according to integrated, ecological and biodynamic production. Downy mildew causes great economic damage in viticulture, especially in the vintages with suitable conditions for the fungi, when it can damage the entire yield, if it is not treated correctly. In the past and still nowadays, especially in the ecological viticulture, the copper fungicides are used against downy mildew. Copper, as a heavy metal, accumulates in soil causing negative impact on the environment. In the integrated pest management, the copper fungicides Cuprablau Z35 WP and Cuprablau Z35 WG are used mostly, while in the biodynamic production the downy mildew control is conducted with various preparations marked with numbers from 500 to 508. Due to the knowledge regarding the negative impact of copper to the environment, we are trying to reduce the use of copper. Scientists are trying to find a new mixture without or with limited quantities of copper. From various plants they obtain extracts which efficiency is tested on vines. Different plant extracts are already used in ecological, but especially in biodynamic viticulture. Studies are conducted also with the microorganisms and on growing of tolerant grapevine varieties. In the next future, the use of pesticides, especially those with copper, will be minor and great efforts are given to tolerant varieties.
