Abstract

Korean thistle (Cirsium setidens Nakai), also called Gondre, is an edible perennial herbaceous plant. A new occurrence of aphids has been confirmed on Korean thistle, which is expected to damage crops. The control effect of organic materials was tested to develop an eco-friendly control method for aphid. Pyrethrins+paraffinic oils exhibited a 98% control effect, pyrethrins+matrine+pyroligneous acid showed a 95% control effect, and azadirachtin+rotenone was found to have a 75% control effect. Pyrethrins appear to be the most effective; no damage (phytotoxticity) was caused with organic materials spraying.

고려엉겅퀴(Cirsium setidens Nakai)는 여러해살이 초본식물로서 식용이 가능하며 곤드레라고 부르기도 한다. 최근 고려엉겅퀴에 여뀌못털진딧물(Capitophorus elaeagni, Del Guercio)의 발생이 확인되어 재배농가의 피해가 예상되고 있다. 이에 대한 친환경적인 방제방법 구명을 위해 시판 유기농업자재를 이용하여 고려엉겅퀴 식물체에 발생한 여뀌못털진딧물에 대한 방제효과를 검정한 결과 pyrethrins+paraffinic oils 이 98% 수준의 방제가를 보여주었으며 pyrethrins+matrine+pyroligneous 가 약 95%의 방제가를, azadirachtin+rotenone 성분이 75% 이상의 방제효과를 보여주었다. 이중 pyrethrins 성분이 가장 좋은 효과를 주는 것으로 여겨지며 유기농업자재 살포로 인한 약해는 발생하지 않았다.
