| Abstract/Contents: | "Background: Repeated useof acetyl-CoA carboxylase (ACCase) inhibitors, especially fenoxapropandclodinafop, since thelate 1980s has selected for resistance in Alopecurus myosuroides Huds. (black-grass) in France.We investigated whether resistance to pinoxaden, a phenylpyrazoline ACCase inhibitor to be marketed in France, was present in French black-grass populations. We investigated pinoxaden resistance conferred by five mutant ACCase isoforms. Using 84 French black-grass field samples, we also compared the frequencies of othermechanisms endowing resistance to fenoxaprop, clodinafop or pinoxaden. Results: ACCase mutant isoforms Leu-1781, Gly-2078 and, likely, Cys-2027 conferred cross-resistance to pinoxaden, while isoform Asn-2041 possibly conferred moderate resistance. Other mechanisms of resistance to fenoxaprop, clodinafop and pinoxaden were detected in 99, 68 and 64% of the samples investigated, respectively. Cross- or multiple resistance to fenoxaprop or clodinafop and pinoxaden was not systematically observed, suggesting a diversity ofmechanisms exist. Conclusion : Pinoxaden resistance was observed before pinoxaden release in France. Only a fraction of the mechanisms endowing fenoxaprop or clodinafop resistance also confer pinoxaden resistance. Pinoxaden resistance was likely mostly selected for by ACCase inhibitors, and, in some cases, possibly by herbicides with other modes of action. This illustrates the necessity to usemetabolisable herbicides cautiously where black-grass has evolved non-target-site-based resistance." |
