Weeds

Weeds pose a serious risk for primary producers as they can impact on market access and agricultural production.

In 2006/07, each Western Australian agricultural business spent an average of $29 376 ($341 million total) on weed control (Australian Bureau of Statistics).

Weed control is a shared responsibility between landholders, grower groups, biosecurity groups and the Department of Agriculture and Food, Western Australia (DAFWA).

To protect Western Australia’s agriculture DAFWA:

  • works with landholders, grower groups, community groups and biosecurity groups.
  • regulates weeds under the Biosecurity and Agriculture Management Act 2007.
  • provides a weed identification service.
  • provides a predictive simulation tool called weed seed wizard.
  • provides information on weed control, crop weeds, regulated/declared plants and herbicides.
  • contributes to social science through weedwatcher.

If you need advice on weeds please search our website, Western Australian Organism List or contact our Pest and Disease Information Service (PaDIS).

For diagnostic services, please contact our AGWEST Plant Laboratories.
