| 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.
