    • The invention relates to novel herbicidal compositions which comprise herbicidal active substances from the class of the phenoxyphenoxy- and heteroaryloxyphenoxy-carboxylic acid derivatives, a dispersant from the class of the fatty alcohol polyoxypropylene-polyoxyethylene ethers and/or the polyoxyethylene-polyoxypropylene block copolymers, emulsifier or wetting agent from the group comprising calcium dodecylbenzenesulfonate, fatty acid polyglycol esters, the ethoxylated nonylphenols and the alkanol polyglycol ethers, organic solvents and water, in the form of microemulsions which have low viscosity and are stable chemically and with regard to their technical properties in use. The invention furthermore relates to a process for preparing these microemulsions by stirring, shaking or static mixing. Prior to the biological application of these formulations, they are mixed with water and thus give spray mixtures which are perfect with regard to their technical properties in use.
    • 本发明涉及新型除草组合物,其包含苯氧基苯氧基 - 和异丙氧基苯氧基 - 羧酸衍生物类别的除草活性物质,来自脂肪醇聚氧丙烯 - 聚氧乙烯醚类和/或聚氧乙烯 - 聚氧丙烯嵌段共聚物类的分散剂,乳化剂 或润湿剂,其包含微乳液形式的十二烷基苯磺酸钙,脂肪酸聚乙二醇酯,乙氧基化壬基酚和链烷醇聚乙二醇醚,有机溶剂和水,其具有低粘度和化学稳定性以及它们的技术性能 使用。 本发明还涉及通过搅拌,摇动或静态混合来制备这些微乳液的方法。 在这些制剂的生物应用之前,将它们与水混合,从而得到喷雾混合物,就其在使用中的技术性质而言是完美的。
