The present invention concerns new pyridyloxy-phenoxy-alkanecarboxylic acid derivatives of the formula ##STR1## wherein A is hydrogen, halogen, alkyl, alkoxy, cyano, nitro or carbothiamide B is hydrogen, halogen, alkyl, cyano, mono- or dialkylamino, alkoxy-carbonyl or carbothiamide C is hydrogen, halogen, cyano, nitro or carbothiamide D is hydrogen, halogen, alkyl, mono- or dialkylamino R.sub.1 is hydrogen, alkyl, alkoxyalkyl or benzyl R is the rest of the acid a salt or an ester, With the proviso that if the pyridine ring is substituted by halogen and/or alkyl and C is also halogen, then the radicals A, B and D must contain no less than two halogen atoms or alkyl radicals. These derivatives have herbicidal and plant-growth regulating activity.
本发明涉及新的吡啶氧基-联苯氧基-烷基羧酸衍生物,其化学式为##STR1## 其中A为氢、卤素、烷基、烷氧基、氰基、硝基或羧硫脲;B为氢、卤素、烷基、氰基、单或双烷基氨基、烷氧基羰基或羧硫脲;C为氢、卤素、氰基、硝基或羧硫脲;D为氢、卤素、烷基、单或双烷基氨基;R.sub.1为氢、烷基、烷氧基烷基或苄基;R是酸的剩余部分,是其盐或酯。但是,如果吡啶环被卤素和/或烷基取代,且C也是卤素,则基团A、B和D必须至少含有两个卤素原子或烷基基团。这些衍生物具有除草和植物生长调节活性。
