Weeds present one of the largest costs to agriculture, with expenditure on weed management and yield loss caused by weeds estimated to cost Australian grain growers over $3 billion annually. Herbicides are by far the most effective weed control tools and therefore the most widely used weed management practice of growers. However, a consequence of the extensive use of herbicides for weed control has been the evolution of herbicide resistant weeds.
Weeds can evolve resistance to herbicides via a variety of mechanisms, and my research focuses on the investigation and understanding of the biochemical and molecular processes involved in these resistance mechanisms.
