Residue of Fungicide Boscalid in Ginseng Treated by Different Spraying Methods

Department of Applied Biology, Chungnam National University, Daejeon 305-764, KoreaThis study was conducted to identify the residue patterns of fungicide boscalid in ginseng cultivated for 4 or 6 years treated by various spraying methods. The pesticide was sprayed separately on ginseng according to safe use guideline, and the field was divided into three groups and they were traditional, soil and vinyl mulching applications. The maximum residue amounts of boscalid were 0.76 mg/kg in traditional application group, 0.69 mg/kg in soil application group, 0.62 mg/kg in vinyl mulching application group in the whole part of 4 years old ginseng, respectively. These residue levels in ginseng exceeded the maximum residue limit established by Korea Food ＆ Drug Administration, which is 0.3 mg/kg.
