A herbicide composition contains a fenoxaprop ester and a weakly acidic buffer system. The pH of the herbicide composition is maintained in the range of from 4 to 8 as a result of the buffer system. In a nonlimiting embodiment, the fenoxaprop ester is fenoxaprop-ethyl or fenoxaprop-P-ethyl. The buffer system may contain an amine-containing substance, for example a tertiary amine. The herbicide composition may contain other herbicides such as weakly acidic herbicides, for example pyrasulfotole, and can furthermore contain one or more safeners.
