Weed Science Research Group - Resources & Highlights
Discoveries and advice from the Weed Science Research Group.
Learn about weed management tactics for broad acre cropping across southern regions of mainland Australia. Here you can find fact sheets as well as links to our researcher's work, including webinars and podcasts.
Our work is regularly featured in GRDC Ground Cover(TM), GRDC research update papers, and WeedSmart resources and articles. These articles provide excellent insight on current issues and topics within weed science including biology, management and herbicide resistance.
Our researchers are also often found speaking about their findings at town halls, sheds and in the paddock beside their trials. More recently, their virtual presence has been appreciated at events outside of South Australia.

Greater weed control was achieved through crop competition offered by an hybrid triazine tolerant (TT) canola compared to an open-pollinated TT, especially when combined with an effective pre-emergent herbicide strategy.
The combination of group A herbicide-resistance plus high seed dormancy makes barley grass increasingly difficult for Australian farmers to control.
Statice is emerging as a significant weed of field crops in the low to medium rainfall areas of southern Australia. It can be effectively managed with an integrated weed management (IWM) plan.
A succession of years with multiple and diverse control options used in varying cropping phases is central to successful ryegrass management.
Herbicide resistance in wild radish is developing fast. Implement an effectively timed 2-spray herbicide strategy and prevent seedset.
Webinars, videos and podcasts
Choosing and applying the right pre-emergent herbicide can be difficult, particularly if herbicide resistance is becoming a challenge in a no-till system. Join Dr Chris Preston and Chris Davey as they explain the new Group G chemistry and de-mystify which Group G works best for winter cropping systems.
Australia has an ever-increasing list of herbicide-resistant weed species and agronomists play a key role not only in identifying and tackling crop weeds but also in protecting chemistries. Join Dr. Chris Preston, Paul McIntosh and Ben Dawson.

WA grower Jamie Greaves talks about blue lupins and then the focus shifts to Feathertop Rhodes grass and how this is proving to be an issue for growers in Northern NSW. Dr Chris Preston and Richard Daniel shed light on this issue and how to get on top of this weed.

How farmers can change the nature of weeds is spotlighted by how quickly barley and brome grasses have reacted to our attempts to control them in cropping paddocks. On this podcast Dr Gurjeet Gill explains the adaption of these grasses, which are now lasting longer in the seedbank.

Barley grass in the southern cropping region is becoming more prominent as a problem weed; as herbicide resistance emerges and as the plant evolves new behaviours. Hear what Dr Gurjeet Gill says about this topic and his region-wide series of trials that are currently underway.
