摘要:
The present invention relates to a composition comprising a pesticide and an alkoxylate. Moreover, the invention relates to the alkoxylate, to a process for its preparation and to its use as adjuvant in pesticide-comprising spray mixtures. The invention furthermore relates to a method of controlling phytopathogenic fungi and/or undesired vegetation and/or undesired insect or mite attack and/or for regulating the growth of plants, wherein the composition is allowed to act on the respective pests, their environment or the plants to be protected from the respective pest, on the soil and/or on undesirable plants and/or the crop plants and/or their environment. Furthermore, the invention relates to seed comprising the composition.

摘要:
The present invention relates to compositions for foam extinguishants which do not comprise any organofluorine compounds and nevertheless meet the highest demands on the extinguishing properties. The inventive compositions comprise at least one fatty alcohol, at least one thickener and at least one acrylic polymer, but the composition does not comprise any organohalogen compounds, more particularly any organofluorine compounds. The present invention also relates to the use of such a composition for production of a foam extinguishant and to the use of the composition for fighting fires, especially for fighting fires of organic liquids, known as liquid fires.
