description

Do herbicide-associated "Safeners" play a role in the selection for non-target-site resistances ? To ensure or improve crop selectivity, some herbicide molecules are applied in association with a “safener”. Safeners are compounds that, at the rate applied, enhance herbicide-degrading metabolic pathways supposedly specifically in crop plants. The metabolic pathways enhanced by safeners in crop plants are highly similar to those exacerbated in taxonomically closely related weed species that evolved non-target-site based resistance (NTSR) to herbicides. Herein, we show an enhancing effect of herbicide safeners on NTSR in a major noxious grass weed: rye-grass (Lolium sp.).
