Herbicidal agents containing as active ingredient a compound of the formula ##STR1## in which R represents halogen, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.2 -alkoxy or C.sub.1 -C.sub.2 -alkylthio, C.sub.1 -C.sub.2 -halogeno-alkyl, NO.sub.2 SO.sub.2 CH.sub.3, SO.sub.2 NH.sub.2, --COOCH.sub.3, CN, with the proviso that R.sub.2 cannot be alkoxy when (R).sub.n is alkyl, R.sub.1 and R.sub.3 represent C.sub.1 -C.sub.6 -alkyl, R.sub.2 represents C.sub.1 -C.sub.6 -alkyl, CH.sub.2 Cl or C.sub.1 -C.sub.6 -alkoxy, X is oxygen or sulfur and n is an integer of from 1 to 3 are especially useful for combatting annual weed grasses in dicotyledonous and even monocotyledonous crop plants.
摘要:
Compounds of the formula ##STR1## exhibit, in the pre-emergence process and in the post-emergence process, a good herbicidal action against a number of dicotyledonous weeds, they are well tolerated in monocotyledonous crops, such as wheat, barley, rice, sorghum and maize, and are also selectively active in some dicotyledonous crops such as soy beans, groundnuts and the like.

摘要:
Phenoxy-phenoxypropionic acid derivatives of the formula ##STR1## wherein R is hydrogen or halogen, and R.sub.1 is substituted alkyl, cyclohexenyl, phenylalkenyl or (substituted) alkinyl, are interesting selective herbicides having a special activity against weed grasses. They are obtained for example by reaction of corresponding phenoxypropionic acid halides with hydroxy compounds of the formula HO--R.sub.1.
