Herbicides

Agents used in viticulture within the large group of pesticides. The name is derived from the Latin terms "herba" (herb, grass) and "caedere" (to kill). Herbicides are divided into algicides(algae), arboricides (woody plants) and graminicides (grasses)). Herbicides are used in agriculture and also in viticulture to control weeds (weeds), although only certain preparations are approved in specific countries. Depending on the application, there are foliar herbicides and soil herbicides. Leaf herbicides are only applied after the plants have sprouted, which is why they are also called post-emergence herbicides.

Herbizide - Brennnessel, Löwenzahn, Distel

The best-known branded products include Basta and Round Up. Soil herbicides are also called pre-emergence herbicides. Well-known branded products are Afalon and Rapir. Relatively new are products that have a strong growth-promoting effect - i.e. the plant grows faster than it can supply itself with nutrients, which leads to death. The most radical are total herbicides, which act on all plants and kill them. Genetic engineering methods are also used to try to breed plants that are resistant to total herbicides.

One has departed from the formerly usual full-surface treatment. The herbicides are rather applied in a narrow strip or in points around the vine. Within the framework of organic viticulture, herbicides are avoided where possible, or at least their use is severely restricted or beneficial insect friendly agents are used. Instead, plant strengthening agents such as auxins are used to increase resistance. Another environmentally friendly measure is the (laborious) mechanical removal of weeds. However, this is particularly difficult on steep slopes.
