GRDC Podcast

Weeds can be especially challenging in High Rainfall Zones, where favourable growing conditions can drive significant weed pressure. Agronomists Luke Wilkins and Candice Robinson share their insights about proactive weed management strategies for tough seasons, including crop competition, herbicide rotation, harvest weed seed control and emerging technologies. They also discuss changing rainfall patterns, paraquat restrictions, brome grass and the role of research in developing future weed control options.

The GRDC investment ‘improving surface and subsurface water management across the medium and high rainfall zones of Australia’ is investigating the benefits and challenges of different drainage options across different production regions, cropping systems and soil types. Grower Jeremy Whyte and agronomist Quenten Knight discuss how landforming uses natural and constructed gradients to assist excess water to flow off paddocks, thereby reducing ponding and waterlogging, and increasing yields. This podcast is part of a 6-part GRDC series on managing soil constraints in Western Australia.

How similar is herbicide resistance in Canada compared to Australia? Research Fellow and weed scientist at the University of Western Australia, William Kramer, shares his global perspective on this challenging issue for growers and his journey in genomics research to better understand what genes are involved in resistance.

William is part of the GRDC Weed Management Initiative research team, run in partnership with The University of Western Australia, The University of Adelaide, Charles Sturt University and The University of Queensland.
