α-取代芳氧基乙酰氧基烃基膦酸酯除草活性研究

Study on the herbicidal activity of α-(substituted phenoxy acetoxy) alkyl phosphonates

用生物测定的方法研究了α-取代芳氧基乙酰氧基烃基膦酸酯系列新化合物的除草活性.结果表明:它们具有很好的选择性除草活性,对双子叶植物效果好,对单子叶植物效果差,具有一定的植物生长调节活性;其生物活性彼此之间存在着较大的差异.另外,探讨了其化学结构与生物活性之间的关系.

In this paper, the herbicidal activities of a type of new compounds have been investigated using the methods of biological test . The following results are obtained: All compounds studied here reveal higher selective,their herbicidal activities are very good to dicotyledon, but poor to monocotyledon. Most compounds can inhibit rooting, and help to produce callus tissues.There are a lot of difference among the compounds in biological activity. In addition, the structure activity relationships have also been discussed in this paper.
