Residue and Dissipation Dynamics of Fluopyram in Cucumber and Soil

Abstract:

The dissipation dynamics and final residues of fluopyram in cucumber and soil were studied. Cucumber and soil samples were extracted with acetonitrile, cleaned up by PSA, determined by gas chromatography with electron capture detection. The LOQ of this method was found 0.003 mg/kg. The results of residual dynamics experiment showed that the half-lives of fluopyram in cucumber and soil were 3.7-4.3 days and 5.8-6.2 days, respectively. Residues of fluopyram in cucumber were all below 0.5mg/kg at both recommended high dosage and 1.5 times of recommended high dosage.
