摘　　要：为了评价三唑酮在中药材金银花上使用的安全性,采用GC分析方法,对三唑酮在金银花及土壤中的残留动态进行了研究。结果表明,三唑酮在金银花和土壤中的半衰期为2.07～4.19d和4.08～7.93d。根据三唑酮在金银花中残留动态的研究结果,结合金银花的药用习惯,建议金银花中三唑酮的最大残留限量(MRL)为1.6mg/kg;提出三唑酮在金银花上的安全使用建议标准:15%三唑酮WP,施药量60ga.i./hm2,采用喷雾的施药方法,在每茬花中最多施药两次,施药间隔为7d,安全间隔期14d。The residue dynamics of triadimefon was studied by GC method to evaluate its safety in honeysuckle. The results showed that half-lives of triadimefon in honeysuckle and soil were 2.07 to 4.19 d and 4.08 to 7.93 d respectively. It＇s suggested that the MRL of triadimefon in honeysuckle is 1.6 mg/kg based on triadimefon residue dynamics in honeysuckle and application habit of honeysuckle. The safe usage standard is recommended that two times of application with seven days interval in every flower period are allowed with the safe interval of fourteen days from harvest when triadimefon 15% WP is applied in the honeysuckle at 60 g a.i./ha.
