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 term 'residual' applies to a number of herbicides that have a long lasting activity in the soil. These herbicides are often applied directly to the soil prior to planting crops, pre-emergent.

  • Spray-topping is a very effective method for managing annual grass seed set in pastures.

  • 'Crop-topping' is the late application of herbicides to prevent weed seed-set.

  • Herbicide performance can vary greatly depending on a number of factors. These can include compatibility of herbicides, water quality, sprayer decontamination and controlling stressed weeds.

  • In Western Australia's Mediterranean-type climate, the survival of pests and diseases over summer is often critical in determining pest outbreaks and disease epidemics in broadacre crops.

  • This article contains useful information about Paterson's curse (Echium plantagineum), how to identify it and biological control agents.

  • Windmill grass (Chloris truncata) is a native species and is the tenth most common summer weed species in the Western Australian wheatbelt.

  • Annual ryegrass (Lolium rigidum) is one of the most serious and costly weeds of annual winter cropping systems in southern Australia.

  • Herbicides play a vital role in integrated weed management programs.

  • 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 interference at seeding time.
