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).
