| 摘 要： | 在大棚栽培条件下，研究了喷施高效氯氰菊酯、氰戊菊酯和三唑酮农药在黄瓜中残留动态和最终残留。结果表明，在推荐用量下高效氯氰菊酯、氰戊菊酯、三唑酮的半衰期分别为1.29、3.15和4.63d。高效氯氰菊酯在黄瓜中的残留量少、降解速度快，二次喷药后3d其残留量远低于我国无公害黄瓜的最高限量标准。在推荐用量下，氰戊菊酯在第3天、三唑酮在第7天的残留量均达到无公害黄瓜标准。

| Abstract: | The residual dynamics and the final residues of beta-cypermethrin,fenvalerate and triadimefon in cucumber were studied in greenhouse.The results indicated that with the recommended dosage,the half-life of beta-cypermethrin,fenvalerate and triadimefon was 1.29 days,3.15 days and 4.63 days respectively.Beta-cypermethrin had lower residue and high degradation rate in cucumber;on the third day after the second spraying,its residue had been much lower than the maximum residue limit of Chinese Standard for pollution-free cucumber.With the recommneded dosage,the residue of fenvalerate on the 3rd day and the triadimefon on the 7th day reached the standard for pollution-free cucumber. |
