Study on determination and dynamics of difenoconazole residues in celery and soil
In order to formulate the standards for safe application of difenoconazole in celery, an analytical method was developed using gas chromatography with electron capture detector for the detection and dynamics of the residues of difenoconazole in this paper.The applications of difenoconazole in celery and soil were discussed to evaluate residue behavior and environmental safety of difenoconazole.The results of residual dynamics showed that the dissipation rates of difenoconazole in celery and soil all followed the first order kinetics.The results of the final residue assay indicated that the residue levels of difenoconazole in celery and soil all increased as the application dosage and application times increased, or as the harvest interval decreased.The results of hydrolysis showed that the degradation of difenoconazole in buffer solutions was difficult.The half-life of difenoconazole in solution was more than 166 d.The difenoconazole is degraded easier in basic solution.
