Phytophthora Dieback

Phytophthora Dieback is a deadly introduced plant disease caused by Phytophthora cinnamomi (pronounced Fy-tof-thora). There are over 50 species of Phytophthora, but the species that causes the most severe and widespread damage to native plants in Western Australia is P. cinnamomi.

Phytophthora Dieback is a serious threat to the Town’s natural areas. It affects many of our mature trees and bushland areas if spread. Human activity causes the most significant, rapid and widespread distribution of this pathogen. Road construction, earth moving, driving infested vehicles on bush roads and stock movement can all contribute significantly to the spread of Phytophthora dieback. Bush restoration projects may also inadvertently spread the pathogen.

Please help us prevent the spread of Dieback by:

• Making sure your mulch is always certified Phytophthora Dieback free. If you’re not sure ask your nursery or wholesaler.
• When walking in bushland areas make sure you stick to the pathways.
• If possible, take a spray bottle with bleach disinfectant and a shoe brush with you, or leave them in your car. Before you enter a site brush off soil from other areas and then spray the bottom and sides of your shoes.

Armillaria luteobublina

Armillaria luteobubalina is a soil borne fungus that causes root rot of a wide variety of plants including many native plants and has been identified within the Town’s natural area. The fungus is native to Australia and causes losses in natural ecosystems. Again, hygiene is essential in preventing the disease from spreading and the above dieback tips for prevention apply.

The Town undertakes testing for Phytophthora Dieback and Armillaria luteobubalina in Council managed reserves and bushlands. Should a resident be concerned about Phytophthora dieback on their private property, it is the resident’s responsibility to conduct testing. The Town requests that any positive testing of Phytophtora or any plant pathogen is reported to the Town.
