title: Determination and study on residue and dissipation of florasulam in wheat and soil under field conditions.
abstract: The residue and dissipation of florasulam in wheat and soil were determined by high performance liquid chromatography-tandem mass spectrometry. The dissipation half-lives for florasulam in soil were 0.66 days in Zhejiang and 0.64 days in Hebei. In wheat plant, half-lives of florasulam were 5.16 days in Zhejiang and 2.07 days in Hebei. The residues of florasulam in wheat grain, wheat straw and soil were below the detection limit (i.e., 0.01 mg/kg, the maximum residue level of florasulam). These results would be helpful in setting MRL guidance of florasulam in wheat in China.
