Abstract

Dissipation constants and half-lives of acaricides etoxazole and flufenoxuron in apples were calculated to establish their pre-harvest residue limits (PHRLs). The acaricides were sprayed on apples with single and triple doses based on safe use guidelines, and their residual patterns in the apple were interpreted using first order kinetics equation. The residual amounts of acaricides during the experimental period were below their maximum residue limits (MRL) for apple. The dissipation constants of acaricides in the apples were calculated at 0.0788 for etoxazole and 0.0319 for flufenoxuron corresponding to their biological half-lives; 8.8~21.7 days for etoxazole and 21.7~23.1 days for flufenoxuron. The PHRLs of acaricides in the apple showed the residual amounts of etoxazole and flufenoxuron at the harvesting date would be below their MRLs if their residual amounts were less than 0.87 and 0.88 mg/kg, respectively, at 7 days prior to harvesting the apples.

사과 중 살응애제 etoxazole 및 flufenoxuron의 출하 전 잔류허용기준(PHRL)을 설정하기 위해 각 농약의 생물학적 반감기와 감소상수가 산출되었다. 안전사용기준의 희석배수에 따라 조제된 각 농약을 사과에 대하여 각각 1회 및 3회 살포한 후 사과 중 일자별 잔류량을 조사하였으며, 잔류시험 결과들은 first order kinetics의 지수감소식에 대입되었다. 시험기간 중 두 농약의 잔류량은 모두 잔류허용기준(MRL) 미만으로 나타났으며, 사과 중 생물학적 반감기를 조사한 결과 etoxazole의 경우 1회 처리구에서 8.8일, 3회 처리구에서 21.7일로 나타났다. 반면에 flufenoxuron은 1회 처리구에서 21.7일, 3회 처리구에서 23.1일로 나타나 etoxazole 보다 반감기가 더 길었다. 사과 중 각 농약의 감소상수는 etoxazole은 0.0788, flufenoxuron은 0.0319이었으며, 산출된 감소상수들을 대입하여 PHRL을 계산하였다. 그 결과, 안전사용기준을 준수한 농약살포 시 출하 일주일 전 농약의 잔류량이 etoxazole은 0.87 mg/kg, flufenoxuron은 0.88 mg/kg 이하이면 출하 시 잔류량이 MRL 이하일 것으로 예측되었다.
