The residual characteristics and risk assessment with respect to cyazofamid and its metabolite 4-chloro-5-p-tolylimidazole-2-carbonitrile were monitored in case of Korean cabbage at different preharvest intervals during a greenhouse trial. The 0.02 kg a.i/ha of cyazofamid was sprayed twice on seven-day intervals (i.e., on day 0, 7, 14, and 21 before harvest). The liquid chromatography–tandem mass spectrometry analysis was used to monitor the residual amount of fungicide. The matrix-matched calibration curves with respect to the cyazofamid in Korean cabbage exhibited good linearity (R² ≥ 0.999) and acceptable recoveries of 84.1%–114.9%. The biological half-life of cyazofamid in Korean cabbage was 3.18 days. During the treatment, the preharvest residue of cyazofamid in Korean cabbage 14 days before harvest (0.80 mg/kg) was lower than that specified by the MFDS–MRL (Ministry of Food and Drug Safety-Maximum Residue Limit, 2.0 mg/kg) and should be recommended as the safe preharvest-interval application limit. The hazard quotient showed low toxicity (70.58%) during the risk assessment study of cyazofamid.

在大棚试验中，以不同的收获前间隔对大白菜进行了氰基法米定及其代谢物4-氯-5-对甲苯基咪唑-2-腈的残留特征和风险评估。每隔七天一次（即收获前的第0、7、14和21天）喷洒0.02 kg ai / ha的cyfafamid。液相色谱-串联质谱分析法用于监测杀菌剂的残留量。大白菜中氰基法米定的基质匹配校准曲线表现出良好的线性（R ² ≥0.999），可接受的回收率为84.1％–114.9％。cyazofamid在大白菜中的生物半衰期为3.18天。在处理过程中，收获前14天韩国甘蓝中的氰唑草胺的收获前残留量（0.80 mg / kg）低于MFDS-MRL（食品和药品安全部最大残留限量2.0 mg / kg）和应建议将其作为安全的收获前间隔施用限量。在氰基法米定的风险评估研究中，该危害商显示低毒（70.58％）。
