Controlled traffic farming plus soil inversion and lime are proving a sound strategy for controlling weeds on the non-wetting sands that make up almost one-fifth of Australia’s cropping land.
Harvest weed seed control has been a major breakthrough in herbicide resistance management, but it’s not a magic fix in isolation. It’s just one of the tools that work together to control weed survivors every step of the way.
Collecting and destroying weed seeds as part of harvest operations is recognised as the most efficient and effective way to implement harvest weed seed control (HWSC), a practice that is expected to be commonplace on up to 80pc of Australian grain farms by 2020.
Widespread rains across the eastern farming zone over the past few weeks have set the scene for a big summer crop planting – and triggered an outbreak of weeds that farmers are now working to contain.
Scientists from the Australian Herbicide Resistance Initiative working on Tridax daisy have discovered a new target-site mutation for glyphosate resistance.
Weed detection and identification is moving into the robotic age at the University of Sydney’s Plant Breeding Institute at Narrabri in north west New South Wales where a high-tech research project is fine-tuning the technology.
A naturally occurring fungus is being harnessed to tackle Noogoora burr, an invasive weed which causes major impacts on agriculture and the environment in eastern Australia.
In an environment of increasing herbicide resistance, getting back in the driver’s seat with weed control relies on stacking tactics and not leaving all the heavy lifting to just one or two strategies.
The Australian Pesticides and Veterinary Medicines Authority (APVMA) has issued new instructions on the use of 2,4-D products to reduce incidents of spray drift this summer.
Growers across Queensland and New South Wales are being encouraged to monitor paddocks for feathertop Rhodes grass with early intervention a potential game-changer for on-farm weed populations later this year.
