  • the invention relates to the technical field of pesticides, in particular that of herbicides for the selective control of weeds and grass weeds in crops of useful plants.
  • This invention specifically relates to substituted heteroaryloxypyridines and their salts, processes for their preparation and their use as herbicides.
  • Plant protection agents known to date for the selective control of harmful plants in crops of useful plants or active ingredients for controlling undesired vegetation sometimes have disadvantages when they are used, be it that they (a) have no or insufficient herbicidal activity against certain harmful plants, (b) too little Spectrum of harmful plants that can be controlled with an active ingredient, (c) insufficient selectivity in crops of useful plants and / or (d) have a toxicologically unfavorable profile.
  • active ingredients which can be used as plant growth regulators in some useful plants lead to undesirably reduced yields in other useful plants or are incompatible with the cultivated plant, or only compatible with a narrow application rate range.
  • Some of the known active ingredients cannot be produced economically on an industrial scale because of the difficult accessibility of precursors and reagents, or they have only inadequate chemical stabilities. In the case of other active ingredients, the effect depends too much on environmental conditions such as weather and soil conditions.
