밀의 재배기간 중 살포된 살균제 fludioxonil 및 metconazole의 부위별 잔류양상을 조사하였다. 밀 부위별 fludioxonil 및 metconazole (cis 및 trans 이성질체의 합)의 잔류분석 회수율은 84.3~113.3%이었으며 변이계수는 0.1~4.7%로 나타나 잔류농약분석 기준을 만족하였다. 두 농약 모두 처리구별 수확된 밀의 짚부위에 가장 많이 잔류되었으며 가식부인 밀알에서 잔류량이 가장 적었다. 밀의 가식부에 잔류하는 농약의 농도는 fludioxonil은 2회 및 3회 살포시 0.01~0.07 mg/kg, metconazole은 0.13~0.17 mg/kg로 나타났다. 침투성 농약인 metconazole은 fludioxonil 보다 더 낮은 농도로 살포되었음에도 불구하고 밀의 가식부로 침투량이 더 많았으며 cis 이성질체가 trans 이성질체 보다 많이 잔류되었다. 밀의 각 부위별 평균무게를 이용하여 밀 한 개체 당 농약의 잔류절대량을 산출하고 밀의 각 부위별 분포율을 산출한 결과, 두 농약 모두 짚 부위에서 68.5~70.7%의 분포율을 나타내었으며 가식부에서 분포율은 0.8% 미만이었다.
