Abstract: A method for the determination of myclobutanil residues in fruits was established with gas chromatogram-nitrogen phosphorus detector (GC-NPD). Residues of myclobutanil were extracted from sample with acetonitrile. After being cleaned up, the final extract was injected into GC with NPD. The detection limit was 0.008 mg/kg, precision and recovery tests were made at the spike level of 0.10, 0.50, 1.00 mg/kg respectively, and the results are as follows: recoveries in the range of 82.2%~97.8%, and relative standard deviation 2.14%~5.51%.

Key words: gas chromatogram, myclobutanil, fruits, determination
