Hey Bloggers and Bloggets
Has anyone ever heard of rust forming on trees? I certainly haven’t – until now. Now it isn’t the type of rust that everyone is use to. No No. The type of rust I am referring to is caused my fungal pathogen that effects Australian natives, like bottle brush (Callistemon spp.), tea tree (Melaleuca spp.) and eucalypts (Eucalyptus spp.) and causes a rust like appearance on the leaves. It also produces powdery bright yellow or orange-yellow spores on infected plants.
This pathogen was first found in Queensland in Dec2010 and has since promoted the Queensland Government to send a mass of emails with two pdfs on what Myrtle rust is and how spreading it can be prevented.
The rust infects plants leaves, flowers and buds (mainly in young plants) and can cause death. It is of concern because of its rapid expansion.
To prevent the spread of such a pathogen vehicles, equipment and clothes should be washed between sites. Alternatively, separate clothing should implemented between sites. You should also minimise the number of items you carry to reduce the risk of the spores attaching to these items. All plant material should also be left in the bush and no plants should be relocated between sites or taken home to be planted in your garden (this hardly works with native Australian plant species anyway).
