The aim of this work is to assess the safety of fungicide tolclofos-methyl, difenoconazole and azoxystrobin 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 main 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 main 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 main body part. In case of vinyl mulching, the residue amount of azoxystrobin was 0.02 mg/kg.
