Australian Herbicide Resistance Initiative - Phase 6

The evolution of herbicide resistance in agricultural weeds is a major concern to the productivity of Australian cropping systems. This project supports developing better weed management strategies to mitigate and manage herbicide resistant weeds through advancement in the understanding of herbicide resistance in key Australian grain cropping weeds at the biochemical, physiological and molecular level.

The investment is part of a new phase of the Australian Herbicide Resistance Initiative (AHRI) that has a renewed national focus, clear development of strategic work priorities, greater emphasis in validating laboratory findings through modelling and field testing and clarity in responsibility of communication outputs, including the use of established channels.
