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.Key words: ACCase; ALS; Echinochloa oryzoides; herbicide resistance. |
