Form of pest Management without the use of chemicals in the various forms of production of the winemaking is used (principles and general information are in the keyword Organic viticulture described, whose study is also recommended as an introduction to the complex topic). Biological crop protection is very important in Integrated crop protection, where biological, chemical and physical measures are combined, and also in organic agriculture, where chemical measures are not allowed. The time of conventional crop protection with massive use of chemical toxins ( pesticides ) is finally over and belongs to the past.
Protection against harmful organisms and other destructive influences is supposed to do that ecosystem do not disturb and take place without toxic substances (poison). The needs of ground. climate, Plants and animals are taken into account. The environment is protected as much as possible, the biological balance is not disturbed and the biodiversity (Biodiversity) guaranteed. Preventive protection is paramount before any measures are taken. In principle, harmful organisms should not be exterminated so as not to destroy unintentionally and counterproductive useful organisms, but to control them in their population so that they remain below the damage threshold. A pest can also be important in nature's cycle.
The oldest form was and is the manual collection of visible pests and the removal of damaged plant parts. Another effective preventive measure is the cultivation of pests and diseases resistant Plants. These include, for example, the use of fungus-resistant PIWI varieties and also the finishing of vines. As an alternative for pesticides are against harmful organisms beneficials specifically used or promoted, which destroy the pests as predators or parasites. These include, for example, insects such as ladybug and lacewings and also nematodes (Roundworms).
There are also manual, mechanical and technical measures for preventive protection of the plants. These include animal traps such as glue rings on the trunk, beer traps or pheromone traps (using disrupter ), Protective devices such as snail fences and bird nets, acoustic / optical devices for the displacement of Schad birds how Klapotetz. scarecrows, Tinfoil strips or shooting devices, as well antifreeze, Fertilization is carried out with organic substances (plant slurry, mulch. compost ) respectively. greening (Green manure) with largely avoiding easily soluble mineral fertilizers.
