Applied in viticulture means within the large group of pesticides, The name derives from the Latin terms "herba" (herb, grass) and "caedere" (kill). The herbicides are converted into algicides ( seaweed ), Arborizide (woody plants) and Graminicides (grasses)). Herbicides are used in agriculture and also in viticulture to combat weed (Bluegrass) are used, whereby country-specific only certain preparations are allowed. Depending on the application, there are foliar herbicides and soil herbicides. The leaf herbicides are only used after the plants have been expelled, which is why they are also referred to as post-emergence herbicides.
Among the best-known brand products are Basta and Round Up. Soil herbicides are also called pre-emergence herbicides. Well-known brand products are Afalon and Rapir. Relatively new are agents that promote strong growth - that is, the plant grows faster than it can provide with nutrients, which leads to dying. Most radical act the total herbicides, which act on all plants and kill them. It is also being tried with genetic engineering methods, against total herbicides resistant To breed plants.
From the previously common full-surface treatment one has strayed. The herbicides are rather introduced in a narrow strip or punctiform around the vine. As part of the Organic viticulture If possible, herbicides are dispensed with, or the use is at least greatly restricted or beneficial insects Means used. Instead, it will open Plant strengtheners such as auxins set, which increase the resistance. Another environmentally friendly measure is the (cumbersome) mechanical removal of weeds. But this is especially in steep slopes difficult.
