本刊讯上海市农科院、上海市农技中心研究人员以灭幼脲为供试农药,运用液相色谱串联质谱法测定了田间施用后桃果实中的灭幼脲残留动态,评估了其残留膳食安全风险,以便为灭幼脲安全施用提供技术支持。试验结果表明,采用液相色谱串联质谱方法检测桃果实中灭幼脲残留,添加回收率在101.2%~116.1%,变异系数为4.8%~8.7%,最低检出限均为0.01mg/kg。施用剂量为
The Journal of Shanghai Academy of Agricultural Sciences, Shanghai Agricultural Technology Center researchers to biuret pesticides for testing, the use of liquid chromatography tandem mass spectrometry field application after peach control of pendimethalin residue dynamics assessed its Residual dietary safety risks to provide technical support for the safe application of mephitis. The results showed that the determination of diflubenzuron residues in peach fruit by liquid chromatography-tandem mass spectrometry was 101.2% ~ 116.1% with a coefficient of variation of 4.8% -8.7%. The minimum detectable limit was 0.01 mg / kg. The dose is
