Long-term Control and Seedbank Depletion of Annual Ryegrass: Management Strategies
Read more about this factsheetAnnual ryegrass is a major winter annual weed of the southern Australian wheat-belt, which naturalised after its introduction as a pasture species. If not managed effectively, ryegrass can significantly reduce the yield of winter crops.
Roly poly
Read more about this factsheetRoly poly down the hill is fun, but the weed doesn't evoke the same joy! Roly poly, also known as prickly saltwort or tumbleweed (Salsola australis R.Br.), is a native species found throughout Australia with the exception of Tasmania (Image 1). The dead plants can break off at ground level, forming the iconic ‘tumbleweeds’ seen in movies.
Tar vine
Read more about this factsheetTar vine This weed is found throughout Australia, with the exception of Tasmania. The origin of this species is unknown, but it may be native to the Kimberly, Pilbara and desert regions of Western Australia. There are twelve species of Boerhavia in Australia, but B. coccinea is the most common in disturbed areas like agricultural […]
Button grass
Read more about this factsheetButton grass can be a pain in the butt! Button grass (Dactyloctenium radulans) sounds kind of cute, but that’s not always the case! It’s a native species found throughout Australia and is a common summer weed species. Like most summer grass weeds it depletes soil moisture and nutrients, reducing the yield potential of the subsequent crop. […]
Herbicide resistant wild radish: take back control
Read more about this factsheetHerbicide resistance in wild radish is developing fast! Effective management to control wild radish populations is imperative to protect your productivity; prevent herbicide resistance and avoid its spread. Key Messages Implement an effectively timed 2-spray herbicide strategy Wild radish size when treated greatly affects herbicide efficacy; always spray small plants Using multiple mode-of-action chemical groups […]
Maximise Clethodim Performance: Impact of Frost
Read more about this factsheetGrowers are reporting variable control of annual ryegrass with clethodim. Poor performance of clethodim can be attributed to cold and frosty conditions. In 2013 and 2014 trials to examine the effect of frost on clethodim treatment of annual ryegrass were conducted under controlled conditions using a frost chamber to mimic a frost event. Key Message […]
Disc seeding systems and pre-emergent herbicides
Read more about this factsheetDisc seeding system design and settings influence pre-emergent herbicide behaviour and can play a critical role in minimising crop damage. Ideal set-up of disc seeding systems, to maximise weed control with pre-emergent herbicides whilst minimising crop damage, requires an understanding of how the products interact with the crop and the distribution of weed seeds in […]
