title: Dissipation and residues of carfentrazone-ethyl in wheat and soil.
abstract: The purpose of this article was to study the dissipation rate of carfentrazone-ethyl in soil and its terminal residue in wheat field eco-system. The results showed that carfentrazone-ethyl dissipated rapidly in soil after application. Its half-lives in soil were 5.8 and 3.8 h in Beijing and Jilin, respectively. The terminal residues of carfentrazone-ethyl in soil samples were very low (around 0.003-0.005 mg/kg), and the residues in wheat grain were not detectable. The use of carfentrazone-ethyl in wheat could be considered to be safe.
