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 fields or […]
Button 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 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 […]
Growers 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 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 […]
