1,3,2-二氮磷杂环戊烷-4-酮类化合物的除草活性

Herbicidal Activity of the Derivatives of 1,3,2-Diazaphospholidine-4-ones

运用油菜根伸长法和小杯法测定了1,3,2-二氮磷杂环戊烷-4-酮类化合物的除草活性,结果表明化合物Ⅰ对油菜和稗草的根茎抑制效果好,化合物Ⅱ对油菜根生长有一定促进作用。

The preliminary bioassay on the derivatives of 1,3,2-diazaphospholidine-4-ones indicated that compounds Ⅰ synthesized displayed significant inhibitory effect against the root-growth and stem-growth of rape and barnyard grass at high concentration; the compounds Ⅱ displayed the promotion activity of the root-growth of rape at high concentration, applying the measures of the rape and barnyard grass root-growth.
