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).


  • The disease ratings for wheat varieties help decide what variety is best suited. Just as paddocks have differing disease and management histories, varieties have differing resistance levels.

  • Yellow leaf spot can have a significant impact on wheat yields.

  • Stem rust (Puccinia graminis f. sp. tritici) is a foliar disease that can significantly reduce wheat yields if it occurrs in early spring and is not controlled.

  • In 2015 powdery mildew reached damaging levels in several regions. With the green bridge leading into the 2016 season, the disease could have significant impacts.
