The m-Cyanoalkoxy-phenylureas of the formula I ##STR1## wherein X is hydrogen or halogen, Y--O is a preferably branched-chain cyanoalkoxy group, and --NR.sub.1 R.sub.2 is a primary, secondary or heterocyclic amino group, exhibit surprisingly good herbicidal activity against mono- and dicotyledonous plants, with a selective action in crops of maize, cereals, cotton and soya bean, and in the case of some of these compounds also in rape crops.
公式I的m-氰烯氧基苯基脲化合物,其中X为氢或卤素,Y-O为优选的支链氰烯氧基基团,-NR.sub.1 R.sub.2为一次、二次或杂环氨基团,表现出对单子叶和双子叶植物有惊人的除草活性,在玉米、谷物、棉花和大豆等作物中具有选择性作用,对于一些这些化合物也对油菜作物有作用。
