摘要

在巴西,阿维菌素已被用于种子处理以控制植物寄生线虫。本研究采用叶面喷雾作为替代施用方法,并建立了采用QuEChERS制备样品的LC-MS/MS方法分析大豆根系中阿维菌素的含量。为此,在叶片上施用阿维菌素,并评价了该农药从叶片到根系的转运。结果表明,该方法具有良好的选择性。采用矩阵匹配方法进行标定。在0.10 ~ 1.0 mg kg-1浓度范围内,分析曲线线性良好,测定系数为0.995。检测限为0.05 mg kg-1,定量限为0.10 mg kg-1。加样回收率在99 ~ 106%之间,RSD <20%。最后对喷叶后的根样品进行分析,未检测到阿维菌素。

Determination of Abamectin in Soybean Roots by Liquid Chromatography Coupled to Tandem Mass Spectrometry
Abamectin has been used by seed treatment to control plant-parasitic nematodes in Brazil. In this work, foliar spray was performed as an alternative application method and a LC-MS/MS method employing QuEChERS for sample preparation was developed for the analysis of abamectin in soybean roots. For this, abamectin was applied on the leaves and the translocation of this pesticide from leaves to roots was evaluated. The method was validated and presented adequate selectivity. Matrix-matched was used as an approach to calibration. Good linearity of the analytical curve was obtained over the studied range of concentrations from 0.10 to 1.0 mg kg-1, with a determination coefficient of 0.995. The limit of detection was 0.05 mg kg-1, and the limit of quantification was 0.10 mg kg-1. Recoveries were in the range of 99 to 106% and RSD < 20%. Finally, root samples after foliar spray were analyzed, and abamectin was not detected.
