Abstract
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.
