摘要

Isoprocarb, hexaflumuron and difenoconazole were used in Perilla frutescens at 600, 60 and 75 g a.i./ha respectively. High performance liquid chromatography-tandem mass spectrometry was used for residue determination because of high selectivity and simple treatment. The results showed that the half-lives of isoprocarb, hexaflumuron and difenoconazole at greenhouse condition were 0.71, 1.63 and 1.21 days respectively, and at field condition, the values were 1.13, 1.07 and 0.92 days respectively.
