The residues of fenpropathrin in apple were studied. After application of fenpropathrin in apple, the residues were extracted from apple with the mixture of acetone and petroleum ether. The extract was cleaned up by liquid to liquid separation and column chromatography, then the sample was determined by gas chromatography with Electron Capture Detector (ECD). In three added concentrations of 0.08, 0.2 and 2 mg / kg, recoveries from apple and apple pulp are in the range of 92.21 %±9.30 to 101.67% ±12.01 and 91.95%±8.16 to 99.62%±3.51, respectively. The minimum detection for fenpropathrin was 1.09×10-10g. The half life of fenpropathrin in apple was 20-30 days and the residues of fenpropathrin in apple at harvest was 401.51μg / kg, which was lower than the Maximum Residues Limit (MRL)-500.0μg / kg.
