This study shows the design, synthesis and evaluation of eco(phyto)toxic and herbicidal activities of quaternary ammonium salts (QASs), derived from haloacetic acids, in context of the search for safer alternatives to the commonly used herbicide, N-(phosphonomethyl)glycine (glyphosate). The structure of the investigated QASs refers to the heteroatom sequence in the anion of glyphosate in which the
这项研究显示了从卤代乙酸衍生的季铵盐(QAS)的生态(植物)毒性和除草活性的设计,合成和评估,以寻求更常用的除草剂N-(膦酰基甲基)的替代品。甘氨酸(草甘膦)。研究的QAS的结构是指草甘膦阴离子中的杂原子序列,其中(PC)-N氮原子被一个或多个卤素(F,Cl)取代。合成QASs的生态毒性是针对发光海洋细菌测试费氏弧菌(了Microtox ®测试)和甲壳类Heterocypris incongruens(Ostracodtoxkit˚F™)。还针对大麦对QAS的植物毒性作用进行了研究(大麦(Hordeum vulgare)和普通萝卜(Raphanus sativus L. radicula Pers。),而除草活性则针对流行的杂草物种勇敢的士兵(Galinsoga parviflora Cav。)和普通的R浆草(Rumex acetosa L.)进行了研究。结果表明,合成的QAS的毒性取决于许多卤素取代基,特别是对于EC
