Charles Sturt University’s Gulbali Institute is delighted to be named one of four key nodes for the Grains Research and Development Corporation’s (GRDC) landmark $47 million Weed Management Initiative (WMI) – a bold, 5.5-year national effort to deliver innovative, sustainable solutions for one of the most persistent challenges in Australian agriculture.

The initiative aims to revolutionise weed control practices through cutting-edge research, development and extension (RD&E), combining national collaboration with regionally tailored strategies.

The Gulbali Institute’s Weed Science team will lead a regional node based at Charles Sturt’s Wagga Wagga campus, working alongside leading institutions: The University of Queensland, the University of Adelaide and The University of Western Australia. Together, these nodes will address the escalating issue of herbicide resistance and the evolving dynamics of weed populations to directly benefit Australian grain growers.

The Charles Sturt node will be led by Professor Michael Walsh, Professor of Plant Science and Horticulture, with a highly experienced research team comprising Dr John Broster, Dr Asad Asaduzzaman, Dr Remy Dehaan, Dr Shawn McGrath and Professor Leslie Weston.

The WMI’s research will focus on three critical pillars:

  • evolutionary dynamics of weed adaptation and herbicide resistance
  • biochemical, molecular and genetic basis of novel herbicide resistance
  • mitigation and management using novel and integrated weed control approaches.

This national collaboration marks a significant investment in the future of Australian grains, strengthening our capacity to combat herbicide resistance and deliver regionally relevant, science-backed weed management solutions.

Impact summary

The $47 million GRDC Weed Management Initiative will transform weed control strategies across Australian grain-growing regions by addressing herbicide resistance through coordinated national research and regional innovation.

Research problem

Weeds remain one of the most costly and persistent threats to grain production in Australia, with escalating herbicide resistance reducing the effectiveness of conventional control measures.

Collaborators

The Gulbali Institute at Charles Sturt University, The University of Queensland, the University of Adelaide, The University of Western Australia.

Outcomes

The initiative will deliver new insights into weed adaptation and resistance mechanisms, trial integrated control approaches and support evidence-based recommendations for sustainable weed management.

Impact

Generating region-specific and nationally coordinated solutions, the program will reduce reliance on herbicides, improve crop yields, and enhance the long-term viability of Australia’s grains industry. Beneficiaries Australian grain growers and agribusinesses, with broader benefits to rural communities, agricultural researchers and national food security.
