돌나물(Sedum sarmentosum Bunge) 중 boscalid+triflumizole 30(20+10)% 수화제의 boscalid에 대한 잔류성 연구 = Residual Studies of Boscalid of Boscalid+Triflumizole 30 (20+10)% WP in the Sedum (Sedum sarmentosum Bunge)

다국어 초록 (Multilingual Abstract)

This study was investigated to determine the residual amounts of boscalid in sedum (Sedum sarmentosum Bunge) using gas-liquid chromatography with electron capture detector (GLC/ECD) and to assess the standard for safe use of boscalid+trifumizole 30 (20+10)% WP. Boscalid is used to control the Botrytis cinerea causing gray mold on sedum. Recovery tests of boscalid in sedum were done by spiking 10 and 50-times of limit of detection (LOD). Recoveries obtained from two concentrations were 95.02% and 88.74%, respectively. The residual amount of boscalid from the sedum harvested 3, 7 and 14 days after 2 and 3-times treatment ranged from 11.68 to 46.20 mg/kg. Because the maxium residue limit (MRL) of boscalid in the sedum is 30.0 mg kg-1, it is proposed for boscalid of boscalid+trifumizole 30 (20+10)% WP to apply 2 times, 7 days before harvest in Korea.
