Definitions

  • the effectiveness of known herbicides against harmful plants is at a high level, but generally depends on the application rate, the respective form of preparation, the spectrum of harmful plants, the harmful plants to be controlled, the climatic and soil conditions, etc., but above all also on the crop plant compatibility .
  • One way of improving the application profile of a herbicide can be to combine a safener with one or more herbicidally active ingredients that contribute the desired additional properties.
  • phenomena of physical and biological incompatibility e.g. B. lack of stability in a co-formulation, decomposition of an active ingredient or antagonism of the active ingredients, or the safeners have a limited range of action, which only protects the crop against one herbicide but not against all components in the case of combined applications of several herbicides.
  • Safeners also called antidotes, of different chemical structures have been known for about 70 years. Likewise, it is known that they differ significantly in terms of their protective functions, i.e. their application is limited to selected herbicides and/or the crop plants to be protected. In addition, it is required that a selected herbicide/safener combination does not negatively influence the herbicidal effectiveness based on the harmful plants to be controlled.
  • the herbicide/safener combinations according to the invention work together in a particularly favorable manner, e.g. when they are used to control undesired plant growth in crops such as wheat (durum and soft wheat), corn, soybeans, sugar beets, sugar cane, cotton, rice, beans (such as bush beans and horse bean), flax, barley, oats, rye, triticale, potato and millet (sorghum).
