AB  - The dynamic and residues of florasulam and flumetsulam in corn field ecosystem 
      were investigated using quick, easy, cheap, effective, rugged, and safe 
      (QuEChERS) procedure with high-performance liquid chromatography-tandem mass 
      spectrometry (HPLC-MS/MS). The limits of quantification (LOQs) of the proposed 
      method ranged from 0.005 to 0.01 mg/kg. Mean recoveries and relative standard 
      deviations (RSDs) of the two compounds in all samples at three spiking levels 
      ranged 94-110 % and 2.0-9.2 %, respectively. Florasulam and flumetsulam 
      degradation followed first-order kinetics with half-lives 1.7-2.9 and 3.3-8.7 
      days in soil and 1.3-1.8 and 0.9-1.7 days in plant, respectively. The residues in 
      all the samples were found to be less than the LOQs at preharvest intervals of 53 
      and 78 days. The results suggest that the combined use of florasulam and 
      flumetsulam on corn is considered to be safe under the recommended conditions and 
      can be utilized for establishing the maximum residue limit (MRL) of florasulam in 
      corn in China.
