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...
A method for determination of metrafenone residues in bitter gourd and soil was developed. All samples were extracted with ethyl acetate, purified with the glass column of florisil and NH2-SPE column, analyzed by gas chromatography with electronic capture detector (GC-ECD). The results showed that it had good linearity in the range of 0.01–2mg/L and the correlation coefficient (r) was 0.9999. The...
