摘　　要：采用高效液相色谱法,研究了多菌灵在新疆葡萄中的最终残留。结果表明,多菌灵最低检出浓度为0.02 mg/kg,添加浓度在0.05~1.00 mg/kg范围内,回收率为70.14%~92.38%,RSD≤6.20%。田间试验结果表明,多菌灵按照低剂量和高剂量各施药3次和4次,28 d后残留量均降至0.17 mg/kg以下,低于多菌灵在葡萄中的最大允许残留量3.0 mg/kg。The final residues of carbendazim in Xinjiang grapes were analyzed with HPLC. The results showed that the lowest concentration of carbendazim detected was 0.02 mg/kg, with recovery of 70.14%-92.38% and RSD of≤6.20% when the forti- fied concentrations were 0.05~1.00 mg/kg. Field experiment results showed that when carbendazim was applied 3 times and 4 times in accordance with the low dose and high dose, residues were reduced below 0.170 mg/kg after 28 d, lower than 3.0 mg/kg, the maximum residue limit of carbendazim in grapes.
