“Implementing narrow windrow burning was not difficult but it did take a couple of years for us to really refine the practice on our farm,” says Robert Gollasch of Wagga Wagga, NSW. He aims to tackle a small area and do it well rather than burn large areas every year. If you are thinking of trying a new approach, read how Robert and others have integrated a range of weed management techniques in WeedSmart case studies from around Australia. WeedSmart also provides access to the ‘10-Point Plan’ to win the battle against crop weeds as well as webinars, videos and other information.
Australian Herbicide Resistance Initiative insights
There is an art to setting up harvesters to maximise the capture of weed seeds. Research aimed at quantifying the harvest losses at different operating speeds found that it doesn’t take a big reduction in engine speed to retain substantially more grain and weed seeds. Stay informed with updates from the Australian Herbicide Resistance Initiative (AHRI) via the AHRI Insights newsletter. Topics include emerging weed issues, herbicide resistance and alternative management techniques such as harvest weed seed control (HWSC). You can subscribe to the email newsletter or read it online.
Integrated Weed Management manual
Choosing to sow cereal crops in an east–west orientation can suppress weed growth and increase crop yields when the weed burden is high, particularly for grass weeds. This technique is more suited to southern Australia, where the sun’s low angle casts a longer shadow. The GRDC Integrated Weed Management manual provides a comprehensive guide to herbicide resistance and the techniques used to manage weeds – from getting the agronomy right, through to preventing weed seed-set.
