摘要: An efficient method has been developed for determining tridemorph in banana using high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). The dissipation and terminal residue of tridemorph in banana fields were carried out at good agricultural practice (GAP) conditions. The average recoveries ranged from 84.4% to 90.0% with relative standard deviations (RSDs) of 3.0%-7.0% at three different spiking levels. The results indicated that the tridemorph dissipated quickly in banana with half-lives of 7.0-7.7 days. The results of residual distribution ranged from 0.01 to 0.26 mg/kg, 0.01-0.62 mg/kg and < 0.01 mg/kg in whole banana, peel and pulp, respectively. The relationship between application factor and residue was discussed. The results of risk assessment showed that the risk quotient (RQ) value was all below RQ = 1. Given that China has not set an maximum residue limit (MRL) value for tridemorph in banana, this study could provide guidance for the reasonable use of tridemorph.
