Resistance to BAY MKHA 6562 in wild oat(avena fatua)

摘要

BAY MKH 6562[flucarbazone-sodium(proposed)], an acetolactate synthase(ALS)-in- hibiting herbicide of the sulfonylaminocarbonyltriazolinone family, provides postemergence wild oat control in wheat. Whole-plant dose responses and in vitro ALS sensitivity assays were used to evaluate the magnitude and nature of cross-resistance to BAY MKH 6562 in a wild oat accession (AR1)with metabolism-based resistance to imazamethabenz, an ALS inhibitor of the imidazolinone family.
