阿维菌素在枸杞果实中的残留动态

Residues of Abamectin in Wolfberry

采用高效液相色谱法研究了1.8%阿维菌素乳油在枸杞果实内的残留动态和最终残留量。残留动态试验表明,阿维菌素在枸杞果实内消解较快,半衰期为1.34～1.50d,在使用浓度6mg/L、施药两次的情况下,最后一次施药距收获间隔期7d,在枸杞果实内未检出。

A high performance liquid chromatography method was used to determine abamectin dissipation dynamics and final residues in wolfberry. Applied 1.8% abamectin EC at dilution of 6 mg/L, the half life of abamectin in wolfberry fruit was 1.34 to 1.50 d, and abamectin was not detected 7 d after application.
