ABSTRACT:
New 2-(substituted-phenoxy)propionic acid derivatives are provided, which have the structure of the general formula: ##STR1## and R.sub.2 is a hydrogen atom or a lower alkyl group. They have a high herbicidal activity to weeds, particularly graminaceous weeds, while they have little or no phytotoxicity to broad leaved crop plants and are therefore useful as selective herbicide.
