Abstract

A survey was performed to investigate major paddy field weeds and frequently used herbicides in Gyeonggi province, Korea in order to establish a system to efficiently control herbicide-resistant weeds. The dominant paddy field weeds included Echinochloa spp. (22%), Eleocharis kuroguwai (14%), Sagittaria trifolia (13%), Scirpus juncoides (12%), Monochoria vaginalis (9%) and Sagittaria pygmaea (7%), and the most widely used herbicides were butachlor 33% CS (25%), benzobicyclon + fentrazamide + imazosulfuron 11.5% SC (9%), cyclosulfamuron + mefenacet 22.2% SC (9%), butachlor 5% GR (6%), and oxadiazon 12% EC (6%) in Gyeonggi province, Korea. Many paddy rice growers considered S. juncoides, M. vaginalis, S. pygmaea and C. difformis as herbicide-resistant weeds. An extensive research deserves to be conducted to monitor occurrence of herbicideresistant paddy weeds in Gyeonggi province, Korea.

한국에서 sulfonylurea계 논 제초제 저항성 잡초들은 전국적으로 확산되고 있다. 경기지역 논 잡초 방제기술 확립을 위한 기초자료로 활용코자 2011년에 경기도 벼 재배면적 2,000ha이상이며 4개 권역으로 구분한 남부(평택시, 용인시), 동부내륙(여주군, 안성시), 서부해안(파주시), 경기북부(연천군) 등 6개 시군의 벼 재배농가를 대상으로 설문 조사하였다. 경기도내 논에서 주로 발생하는 논잡초는 피, 올방개, 벗풀, 올챙이고랭이, 물달개비, 올미, 자귀풀, 알방동사니, 가막사리, 여뀌바늘 순이었으며, 주로 사용하는 제초제는 뷰타클로르 캡슐현탁제, 벤조비사이클론펜트 라자마이드 이마조설퓨론액상수화제, 사이클로설파뮤론 메페나셋액상수화제, 뷰타클로르입제, 옥사디아존유제 순이었다. 발생 논잡초 중 농가가 SU계 제초제 저항성으로 의심하는 논잡초는 올챙이고랭이, 물달개비, 올미, 알방동사니 등이 있는데, 논토양 저항성잡초 포트검정 결과 물달개비와 올챙이고랭이가 저항성잡초로 추정되어 금후 저항성 논잡초 발생 모니터링을 통하여 보다 정밀한 연구가 필요하며, 저항성 논잡초에 대한 효율적인 방제기술 체계확립이 요구된다.
