Abstract

This 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.

인삼 중 농약 잔류량 조사 결과 부적합율과 검출 빈도가 높은 boscalid 농약에 대하여 부적합 원인을 구명하기 위해 안전사용기준에 따라 농약을 살포하되, 그 살포방법을 달리하여 잔류량을 분석하였다. 인삼은 4년근과 6년근을 사용하였으며 분석 시 인삼의 뇌두와 몸통을 나누어 분석하였다. 그 결과 boscalid의 잔류량은 몸통부분보다 뇌두부분에서 더 많은 양이 검출되었으며, 랩 처리구의 잔류 결과로부터 boscalid의 흡수이행 경로를 추정할 수 있었다. 또한 인삼의 전체부위에 대한 최대 잔류량은 4년근 인삼의 관행 처리구에서 0.76 mg/kg, 토양 처리구에서 0.69 mg/kg, 랩 처리구에서 0.62 mg/kg으로 나타났으며, 6년근 인삼에서의 전체부위에 대한 최대 잔류량은 관행 처리구에서 0.74 mg/kg, 토양 처리구에서 0.40 mg/kg, 랩 처리구에서 0.28 mg/kg으로 나타나 4년근 인삼에서 6년근 인삼보다 더 많은 잔류량을 나타내었다. 뿐만 아니라, 4년근과 6년근 인삼 모두 식품의약품안전청에서 제시한 잔류허용기준인 0.3 mg/kg을 초과하였다.
