Medium used in viticulture within the large group of pesticides, The name is derived from the Latin terms "herba" (herb, grass) and "caedere" (kill). The herbicides are used in algicides ( seaweed ), Arborizide (woody plants) and Graminizide (grasses) differentiated). Herbicides are used in agriculture and also in viticulture to control weed (Ungras) used, with country-specific only certain preparations are allowed. Depending on the application, there are leaf herbicides and soil herbicides. The leaf herbicides are only used after the plants have been driven out, which is why they are also called post-emergence herbicides.
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 agents that have a strong growth-promoting effect - this means that the plant grows faster than it can supply itself with nutrients, which leads to death. The most radical are the total herbicides, which act on all plants and kill them. Genetic engineering methods are also being used to combat total herbicides resistant To grow plants.
One has strayed from the full-surface treatment that used to be common. Rather, the herbicides are applied in a narrow strip or point-like around the vine. As part of the Organic viticulture herbicides are avoided if possible, or the use is at least severely restricted or beneficial insects Means used. Instead it gets on Plant strengtheners such as auxins set, which increase the resistance. Another environmentally friendly measure is the (tedious) mechanical removal of weeds. But this is especially in steep slopes difficult.
