복숭아 재배기간 중 살균제 Fenarimol과 살충제 Flufenoxuron의 생산단계 잔류허용기준 설정

BACKGROUND: This study was performed to establishment the PHRLs of peach during cultivation period, and also to estimate biological half-lives for residues of fenarimol and flufenoxuron. METHODS AND RESULTS: The extracted samples of fenarimol were analyzed by GC-ECD and the flufenoxuron extracted samples were analyzed by HPLC-DAD. Recoveries of fenarimol at two fortification levels of 0.1 mg/kg, 0.5 mg/kg were 93.69±6.56 (%) and 94.45±1.60 (%), respectively. And recoveries of flufenoxuron at two fortification levels of 0.1 mg/kg, 0.5 mg/kg were 106.73±5.90 (%) and 96.37±6.66 (%), respectively. CONCLUSION(S): The biological half-lives of fenarimol in single treatment and triple treatment were 3.5day and 3.8day. thatof Flufenoxuron was also 7.1day and 4.9day, respectively. The PHRL of fenarimol were recommended as 1.5 mg/kg for 10day before harvest and the PHRL of flufenoxuron were recommended as 1.4 mg/kg for 10day before harvest.
