Plant disease

Plant diseases such as Phytophthora dieback compromise the integrity of the bushland. It is important that you exercise good plant hygiene when entering any of the City’s reserves as well as your own backyard to prevent the spread of this biological bulldozer.

Phytophthora dieback is a disease which causes plants to look like they are dying back. Dieback affects the roots of susceptible plants and prevents the uptake of water and nutrients. This leads to the gradual death of the plant.

Dieback is present in the south-west of Western Australia and affects Banksia woodlands, Jarrah forests, private and public gardens and streetscapes. The spread and establishment of dieback is most common in wet areas.

Unfortunately there is no known way to eradicate Phytophthora dieback and the best way to manage the disease is to prevent it spreading into new areas. Phytophthora dieback is spread mainly through soil and moisture movement and as a precaution all shoes, tyres and equipment entering a bushland should be cleaned of all soil material first, either by washing with a one per cent bleach solution with water and boots with methylated spirits.
