Allelic variation of the ACCase gene and response to ACCase‐inhibiting herbicides in pinoxaden‐resistant <b><i>Lolium</i></b> spp.

Abstract

Almost all the ACCase mutations selected in the field by other ACCase inhibitors are likely to confer resistance to pinoxaden. Although pinoxaden is sometimes able to control FOP-resistant populations, it should not be considered as a sustainable ACCase resistance management tool. The presence of non-ACCase-based resistance mechanisms that could confer resistance to herbicides with different modes of action further complicates the resistance management strategies.
