You'd be forgiven for not knowing what this new killer plant disease is. It was only discovered in Australia in 2010 but already has swept across 4 states and promises to cover our entire continent very quickly.

Australia has so many Myrtaceae species, we can expect to be severly affected by this South American fungal disease.

As yet I have not heard of any treatments and certainly no cure.

We may find it infesting our Myrtaceae family fruiting andproductive trees such as GUavas, feijoas, Syzygiums like Rose Apples and Lillypillies, Backhousia the Lemon Myrtle (my favourite) Jaboticabas and Cinnamon and Aniseed myrtle.

 However, eucalypts, tea trees, Acmena, Mangroves, Melaleuca and our beloved bottle brushes may all be affected too.

The Sunday Mail did an article this weekend just gone and there is a article on the link below.

What can we do and what should we do about it?

According to the QLD DPI website, Myrtle rust is reportable. Here is an excerpt from their page:

Do I need to tell someone if I suspect myrtle rust in my backyard?

Reporting is essential to enable Biosecurity Queensland to keep track of the spread of infection and update the known host list. Call 13 25 23 to report any suspected plants. Myrtle rust is a reportable plant disease under Queensland legislation.  Their website:

  • Now that's the second time I have heard of this in the last week or so. From what I heard (and I have not read the article) it appeared in Tea Tree plantations. I think that may be a clue: a monoculture and not one run Biodynamically nor even Organically as far as I know. That the industry can sell its organic matter on the open market says that they do not compost their own stuff and re-use it.
