Common roegneria, a perennial weed in Roegneria genera of the tribe Triticeae (family: Poaceae), is widely distributed in China and could not be effectively controlled by acetyl coA carboxylase (ACCase) inhibitors in wheat in some regions. This study aimed to quantify herbicide tolerance level and investigate its mechanisms of ACCase tolerance in common roegneria. Whole-plant dose–response assay indicated that populations ZJJX and HBJZ (collected in wheat fields) exhibited high tolerance [ED50s >16-fold labeled field rate (LFR)] to fenoxaprop-P-ethyl and clodinafop-propargyl [aryloxyphenoxypropionate (APPs)] and pinoxaden (phenylpyrazolin). In addition, two populations collected from uncultivated areas showed similar responses to these herbicides. All common roegneria populations were susceptible to haloxyfop-R-methyl and quizalofop-p-ethyl (APPs), clethodim, and sethoxydim (cyclohexanediones) (ED50s |
