The plants identified here have the potential to cause significant damage to Western Australia's pastoral industry and to the unique biodiversity of the rangelands.
In 2021 the Department is conducting over 300 research trials across the state from Kununurra in the north to Esperance in the south.
Introducing new plants to an area can have positive and negative effects on the environment, economy and community.
This project aims to determine the spread of emerging summer weeds and deliver new knowledge on the biology and management of these emerging summer and winter weeds, with an overall aim of increasi
The viability of annual ryegrass seed can be reduced substantially by desiccation, pre-harvest spraying or swathing of canola depending on the product and timing.
Tar vine (Boerhavia coccinea) is found throughout Australia, with the exception of Tasmania.
The Pest and Disease Information Service (PaDIS) provides advisory and identification services on animal and plant pests, weeds and diseases that impact Western Australia's agriculture and food ind
An 11 year study showed that narrow row spacing and harvest weed seed destruction (that is, residue burning each autumn) reduced annual ryegrass seed production.
Summer weeds can rob subsequent crops of soil nitrogen and stored soil water. They can also reduce crop emergence by causing physical and/or chemical interfence at seeding time.
Pasture manipulation is the application of herbicides for grass control early in the growing season (autumn or early winter).
It is often the preferred option for grass control.
