Flumorph is an oomycete fungicide that is now used extensively in China. A residue analysis method for the determination of flumorph in environmental samples was developed with solid-phase extraction (SPE) for sample preparation and high-performance liquid chromatographic (HPLC) for separation. An environmental fate study was performed concerning the degradation of flumorph in soils, aqueous buffer solutions, and natural waters under laboratory-controlled conditions. The degradation of flumorph in three Chinese soil samples followed a first-order kinetics, with half-lives all longer than 100 days. No degradation of flumorph occurred in aqueous buffer solutions having different pH values or in natural waters with different physical and chemical properties. The data generated from this study could be helpful for risk assessment studies of the pesticide in the environment.
