摘要:利用液相色谱仪建立呲唑醚菌酯在平鍌和榆黄蘑中残留分析方法,测定吡唑醚菌酯在平菇和榆黄蘑及培养料
中的消解动态规律。结果表明:呲唑醚酯在平菇和榆黄蘑及培养料中的消解半衰期分别为2.8、2.9d和14.1d,培养料
灭菌会减少呲唑醚酯的残留量。平菇和榆黄蘑及在含有吡唑醚菌酯的培养料中栽培90d后,培养料中供试农药残留
量0.68mg/kg,在收获期同步采集的平菇和榆黄蘑子实体中均未检测到吡唑醚蔺酯的残留量。因此,培养料中呲唑醚茵
酯残留不会向平菇和榆黄蘑子实体转移,对食用菌产品质量安全的影响較小

Abstract: A high performance liquid chromatography (HPLC)method was developed for the determination ol
pyraclostrobin residues in Pleurotus ostreatus and Pleurotus citrinopileatus. The degradation kinetics of the
pyraclostrobin in Pleurotus ostreatus, Pleurotus citrinopileatus and substrates was thus studied. The results
indicated that the half-life period of pyraclostrobin in Pleurotus ostreatus, Pleurotus citrinopileatus and
substrates were 2.8, 2.9 d and 14.1 d respectively. Sterilization remarkably reduced pyraclostrobin residues in
the substrates. After Pleurotus ostreatus and Pleurotus citrinopileatus were cultivated for 90 days in the
substrates with pyraclostrobin, with the tested pesticide residues in the substrates being 0.68/k, no residual
olume was deteeted in the substance of Peurotus ostreatus or Pleurotus citrinopileatus that were harvested at
the same time. Therefore, pyraclostrobin residues in substrates didnt transfer to the fruiting bodies of Pleurotu
ostreatus or Pleurotus citrinopileatus and thus had little impact on the quality safety of the edible fungus

随着人们对食用菌安全的关注度越来越高,食用中的多种病害防治?。日前有关吡唑瞇菌酯在作物
菌作为纯天然食品具有独特的食用和药用及保健功蔬菜上的残留降解均有报道,但在食用菌上的消解

食用菌在生产过程中,容易受到农药污染,给人类的榆黄蘑上残留的分析方法,研究了吡唑醚菌階在平姑
健康带来危害。因此,研究农药在食用菌上的残留和榆黄蘑及培养料中的消解动态规律,为指导吡叱唑醚
