title: Dissipation of clodinafop-propargyl and its metabolite in wheat field ecosystem.
abstract: The dissipation and residues of clodinafop-propargyl and clodinafop in wheat and soil were investigated by high performance liquid chromatography-tandem mass spectrometry. Clodinafop-propargyl rapidly degraded to the acid derivative-clodinafop as major metabolite in plant and soil. The half-lives of clodinafop-propargyl were 2.35-11.20 days in soil and 6.00 days in wheat plant. The half-lives of clodinafop were 7.04-11.22 days in soil and 0.67-1.24 days in wheat plant. The residues of clodinafop-propargyl and clodinafop in wheat grain, wheat straw and soil were below the detection limit.
