Abstract

Weeding effect was investigated based on the leaf stages to several different herbicide treatments for an integrated weed management of herbicide resistant Echinochloa oryzoides to ACCase and ALS inhibitors in a rice field. Efficacy of soil-applied herbicide treatments before resistant E. oryzoides occurred was very effective. Pentaxazon 5% SC showed over 98% of weeding effect although E. oryzoides were emerged 31 days after the treatment. Until the leaf stage of 2.5, five herbicides, azimsulfuron carfenstole 1.05% GR, bensulfuron-methyl benzobicyclone mefenacet 24.52% SC, bensulfuron-methyl fentrazamide 7% SC, bensulfuron-methyl mefenacet oxadiargyl 21.6% SC and mefenacet pyrazosulfuron-ethyl 3.57% GR showed perfect weeding effect. Benzobicyclone mefenacet penoxulam 21.5% SC and mefenacet pyrazosulfuron-ethyl 3.57% GR were effective at the leaf stage of 3.0. It is very important to select the right herbicides for timing and their systematic application for controlling of E. oryzoides resistant to ACCase- and ALS-inhibitors.

제초제 저항성 피의 종합방제를 위해 약제별, 엽기별 방제효과를 확인하였다. 저항성 강피 발생전 토양처리 제초제의 효과는 옥사디아길 1.7% 유제, 옥사디아존 12% 유제, 펜트라자마이드 옥사디아길 3.3% 유제의 3종에서 100% 방제되었으며, 펜톡사존 5% 액상수화제는 약제처리 후 31일부터 후발 피가 발생되기도 하였으나 98% 이상 우수한 효과를 보였다. 저항성 피 1.0~2.5엽까지 100% 방제가 가능한 제초제는 아짐설퓨론 카펜스트롤 1.05% 입제, 벤설퓨론 메틸 벤조비사이클론 메페나셋 24.52% 액상수화제, 벤설퓨론메틸 펜트라자마이드 7% 액상수화제, 벤설퓨론메틸 메페나셋 옥사디아길 21.6% 액상수화제, 메페나셋 피라조설퓨론에틸 3.57% 입제 등 5종이었다. 피 3.0엽기까지 방제가 가능한 제초제는 벤조비사이클론 메페나셋 페녹슐람 21.5% 액상수화제와 메페나셋 피라조설퓨론에틸 3.57% 입제등 2종이었다. ACCase 및 ALS 제초제 저항성 피를 완벽하게 관리하기 위해서는 발아전 제초제와 초 중기 토양처리제초제의 선택과 이들 제초제의 체계처리가 중요할 것으로 판단된다.
