Weed control in Australian crops has been through a revolution over the last three decades, transforming from a dependency on cultivation, with associated soil degradation issues, to herbicide reliance in conservation agriculture (CA) systems. The resulting dramatic change in the crop production environment has resulted in a similarly significant impact on weed control practices. The adoption of CA is underpinned by the availability of highly efficient, selective herbicides, but the absence of alternate weed control technologies has led to an over-reliance on herbicides. The widespread evolution of herbicide resistance now threatens the sustainability of CA systems (Powles and Yu 2010).
