This study is conducted in order to know the residue patterns of insecticide cypermethrin and fungicide diethofencarb in ginseng sprayed by various application methods. Two pesticides were sprayed separately on ginseng using traditional, soil and vinyl mulching applications. The vinyl mulching application was that head part of ginseng protected from pesticides. When cypermethrin was sprayed on ginseng by traditional application, its residue amount in ginseng was 0.25 mg/kg which exceeded 0.1 mg/kg, maximum residue limit(MRL) established by Korea Food ＆ Drug Administration(KFDA). But in case of vinyl mulching and soil application, its residue amounts were 0.04 and 0.07 mg/kg, respectively. The residue amount of diethofencarb in ginseng was 3.01 mg/kg which exceeded the MRL, 0.3 mg/kg. Further, in case of vinyl mulching and soil application, its residue amounts were 1.71 and 9.39 mg/kg which exceeded the MRL 0.3 mg/kg. Although the residue amounts of both pesticides exceeded the MRLs for ginseng, we can explain that pesticides remained in head part of ginseng is probably the reason why higher pesticides residue levels were observed.
Abstract
This study is conducted in order to know the residue patterns of insecticide cypermethrin and fungicide diethofencarb in ginseng sprayed by various application methods. Two pesticides were sprayed separately on ginseng using traditional, soil and vinyl mulching applications. The vinyl mulching application was that head part of ginseng protected from pesticides. When cypermethrin was sprayed on ginseng by traditional application, its residue amount in ginseng was 0.25 mg/kg which exceeded 0.1 mg/kg, maximum residue limit(MRL) established by Korea Food ＆ Drug Administration(KFDA). But in case of vinyl mulching and soil application, its residue amounts were 0.04 and 0.07 mg/kg, respectively. The residue amount of diethofencarb in ginseng was 3.01 mg/kg which exceeded the MRL, 0.3 mg/kg. Further, in case of vinyl mulching and soil application, its residue amounts were 1.71 and 9.39 mg/kg which exceeded the MRL 0.3 mg/kg. Although the residue amounts of both pesticides exceeded the MRLs for ginseng, we can explain that pesticides remained in head part of ginseng is probably the reason why higher pesticides residue levels were observed.
