This project will undertake a weed survey of commercial production areas in Australia’s primary lucerne seed growing region. This survey will collect seeds samples for resistance screening and will generate data about the current level of herbicide resistance in annual ryegrass, barley grass and sowthistle.

These survey results will inform the development of integrated weed management guidelines for the lucerne seed industry, with the aim to extend the life of important herbicides. This research will also inform the industry of the extent of resistance, and help farmers and advisers take a longer-term view of resistance risk management, improving the profitability and sustainability of the Australian Lucerne Seed Industry.
