摘　　要：建立测定水稻植株和田水中肟茵酯残留量的高效液相色谱串联质谱法(LC—MS/MS),并研究了肟菌酯在水稻植株和田水中的消解规律。结果表明:肟茵酯在水稻植株和田水中的添加回收率为91.4%~108.5%。变异系数为2.0%~8.7%。肟茵酯在水稻植株和田水中的消解半衰期分别为5.92d和0.348d。A method was developed for the determination of trifloxystrobin in rice plants and water by liquid chromatography tandem mass spectrometry(LC-MS/MS) detection.The tests on the residue dynamic degradation of trifloxystrobin in rice plants and water were carried out.The average recoveries of trifloxystrobin were 91.4%~108.5%,with relative standard deviation(RSD)of 2.0%~8.7%,in rice plants and water.The half-lives in rice plants and water were 5.92 d and 0.348 d respectively.
