Abstract: To efficiently monitor the residues of fruits, a simple and fast residual analytical method of pyraclostrobin in apples and soil was established. The mixed solution of ethyl acetate and acetone was utilized to extract the pyraclostrobin in samples. After nitrogen blowing to nearly dry, methanol was added to dissolve the residue and then the supernatant was detected by HPLC-UV. The results showed that under the additional level of 0.01-5.0 mg/kg, the recovery rates of pyraclostrobin in apples and soil were 86.7%-98.2% and 79.8%-90.5% with the RSD of 0.01%-4.1% and 0.2%-2.5% respectively. The LOD was 0.01 mg/kg. The method was simple, rapid and less interference. The sensitivity and accuracy of the proposed method were fit for analysis of pesticide residue in fruits and soil.
