The aim of this work is to assess the safety of pesticides in ginseng sprayed by safe use guideline. When tolclofos-methyl was sprayed on ginseng by safe use guideline, the residue amounts(MRL) of it in ginseng was 0.13 mg/kg which is below than 0.3 mg/kg, maximum residue limit established by Korea Food & Drug Administration(KFDA). The residue amounts of ginseng parts, head part was 0.37 mg/kg and body part was 0.13 mg/kg. In case of difenoconazole, the residue amounts in ginseng was 0.81 mg/kg. which was exceed the MRL, 0.2 mg/kg. By the analyze results of ginseng part, the residues of head and body part were 3.01 and 0.40 mg/kg, respectively. In experiment of vinyl mulching, the residue amount of difenoconazole in ginseng was 0.05 mg/kg. The residue amounts of azoxystrobin in ginseng sprayed by safe use guideline was 0.14 mg/kg. This residue was not exceed the MRL 0.5 mg/kg. The residue amounts by ginseng parts was 0.51 mg/kg for head part and 0.28 mg/kg for body part. In case of vinyl mulching, the residue amount of azoxystrobin was 0.02 mg/kg. 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, MRL established by 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.
