Fungi

Fungi are eukaryotic (membrane bound nucleus) organisms that develop from reproductive bodies called spores. They can cause a number of diseases in animals and plants. As a disease of plants and animals, fungi are a risk for Western Australian primary producers as they impact upon market access and agricultural production.

WA is free from some of the world's major fungal diseases. Biosecurity measures on your property are vital in preventing the spread of fungal diseases.

The Department of Primary Industries and Regional Development provides:

  • biosecurity/quarantine measures at the WA border to prevent the entry of fungal diseases.
  • where relevant post border biosecurity measures.
  • advice on widespread fungal diseases present in the state.

For advice on fungal diseases search our website, the Western Australian Organism List or contact our Pest and Disease Information Service (PaDIS).

For diagnostic services, please contact our Diagnostic Laboratory Services.
