Control methods

Pests, weeds and diseases (pests) pose serious risk for primary producers as they can impact on market access and agricultural production. Pest control is best achieved with an Integrated Pest Management plan using a range of biological, chemical, mechanical, physical or cultural control methods.

To reduce the impacts of pests, the Department of Primary Industries and Regional Development:

  • works with landholders and grower/community/biosecurity groups on control
  • provides diagnostic services and information on prevention, management and treatment
  • provides biosecurity measures to prevent introduction, and to eradicate or manage current pests.

For advice on control methods search our website or contact our Pest and Disease Information Service (PaDIS).

  • In 2021 the Department is conducting over 300 research trials across the state from Kununurra in the north to Esperance in the south.

  • Herbicides can be applied by a variety of means including boom sprayers, aerial spraying, misters, blanket wipers, rope wick applicators, weed seekers and back-pack sprayers.

  • Options for control of winter broad leaved weeds, in pastures, is a common inquiry. A fairly reliable method is spray grazing.

  • In Western Australia, competition from 7-90 capeweed plants per square metre in a wheat crop can reduce crop yield by 28-44% and net return by 25-76%.

  • This management strategy provides an opportunity to control weed seed set in the pasture and during harvest.

  • Doublegee or spiny emex is a significant weed in Western Australia. It is a vigorous annual herb with a strong tap root and a long, fleshy, hairless stem.

  • Herbicide resistance is the inherited ability of an individual plant to survive a herbicide application that would kill a normal population of the same species.

  • Following the extended dry conditions this autumn, weeds are now emerging and becoming a challenge for growers to manage in paddocks that may have patchy crops, crops with staggered emergence or no

  • Integrated weed management (IWM) is a system for managing weeds over the long term, and is particularly useful for managing and minimising herbicide resistance.

  • Testing for herbicide susceptibility allows you to determine what herbicide options are still available to control weeds on your farm.
