Abstract

The occurrence of sulfonylurea-resistant weeds has recently increased in Korea. A survey was performed to investigate major paddy field weeds and frequently used herbicides in Gangwon province, Korea in order to establish a system to efficiently control herbicide-resistant weeds. The dominant paddy field weeds included Monochoria vaginalis (14%), Sagittaria trifolia (14%), Scirpus juncoides (13%), and Echinochloa spp. (13%), and the most widely used herbicides were oxadiazon 12% EC (27%), butachlor 5% GR (20%), oxadiargyl 1.7% EC (16%), and benzobicyclon+imazosulfuron+pyriminobac-methyl 6.1% SC (14%) in Gangwon province, Korea. Many paddy rice growers considered Scirpus juncoides, S. trifolia, Echinochloa spp. and M. vaginalis as herbicide-resistant weeds. An extensive research deserves to be conducted to monitor occurrence of herbicide-resistant paddy weeds in Gangwon province, Korea.

최근 설포닐우레아계 제초제에 저항성을 보이는 논잡초의 발생이 증가하는 경향을 보이고 있다. 이를 효과적으로 방제하는 시스템을 구축하기 위한 기초 자료로 활용하고자, 강원도 쌀 재배 농업인들을 대상으로 잡초 발생 및 제초제 사용에 대한 설문조사를 하였다. 많이 발생하는 잡초는 물달개비, 벗풀, 올챙이고랭이, 피류 등이었으며, 주로 사용하는 제초제는 옥사디아존유제, 뷰타클로르 입제, 옥사디아길 유제, 벤조비사이클론 이마조설퓨론 피리미노박메칠 액상수화제 등이었다. 농업인들이 저항성으로 의심하는 잡초로는 올챙이고랭이, 벗풀, 피류, 물달개비 등이 있는데, 앞으로 모니터링을 통하여 정밀 조사가 필요하며, 저항성 잡초에 대한 효율적인 방제로 생산비를 줄이고 작물수량을 높일 수 있다.
