Abstract

In this experiment, the dissipation dynamics and residue distribution of fluopyram, trifloxystrobin, and their metabolites [2-(trifluoromethyl) benzamide (BZM) and trifloxystrobin acid] during the growth process of loquat were carried out by ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS).Samples were extracted with acetonitrile, purified with an amino solid phase extraction column, and analyzed by UPLC-MS/MS.Results showed that at three spiked levels of 0.01-1 mg/kg, the average recoveries were 82%-93%, the relative standard deviation (RSD) was 1.4%-2.8%, and the limit of quantification (LOQ) was 0.01 mg/kg.The method had good sensitivity and accuracy and could meet the requirements for residue detection in loquat.According to the guidelines for field trials of pesticide residues, the field trial results showed that when fluopyram · trifloxystrobin 43% suspension concentrate (SC) was applied at dosage of 333 mg/kg for 2 times with application interval of 10-15 days, and 28 and 35 days after the last application, the residues and dissipation rate of fluopyram and trifloxystrobin was <0.01-0.03 mg/kg and >90%, <0.02-0.04 mg/kg and >85%, respectively.The residue of trifloxystrobin was lower than the maximum residue limit formulated in China (0.7 mg/kg).The dietary risk assessment results showed that it did not pose a chronic risk to the general population according to the recommended dosage.The research results can provide data and technical support for guiding the scientific and rational use of fluopyram and trifloxystrobin in loquat.

Key words： loquat; fluopyram; trifloxystrobin; residue analysis; dietary risk assessment
