Abstract: A study was carried out to investigate the degradation dynamics of cyhalofopbutyl (XDE537) in soil, which is an active ingredient of a herbicide Clincher.Samples were collected from paddy fields in Fuyang, Hangzhou, Peoples Republic of China and XDE537 and its degradation products were determined. Cyhalofop (ACID) was observed to be the first degradation product that later changed into inactive form DIACID. XDE537 was found to undergo almost instant degradation in soil and to levels below the detection limit. ACID was comparatively slower although fairly fast in fact (five days). It was observed that most of the DIACID is derived from ACID. Because of the rap id reaction in soil and eventual disappearance of XDE537, ACID and DIACID, it was suggested that the herbicide Clincher is nonpersistent in the environment.
