Myrtle Rust is a major new threat to Australia’s flora. This information hub has been developed by the ANPC to contribute to response capabilities here in Australia and overseas.
The ANPC has been at the centre of attempts by concerned scientists and conservation practitioners to develop a coordinated and funded national response to this threat. Your support for our work in this area, and on broader aspects of environmental biosecurity, would be welcome – please contact the office.
*FILM RELEASE – Myrtle rust, the silent killer*
This film introduces myrtle rust and its cultural, social and ecological effects on Australia’s native environment. Indigenous rangers, scientists and landowners share their first-hand stories of this fungal disease and its impact on our precious species and landscapes. We learn about their efforts to bring species back from the brink of extinction and the value of protecting our unique ecosystems from biosecurity threats for generations to come.
This film was a collaborative project led by Queensland Agriculture with support from the ANPC, the San Diego Zoo WIldlife Alliance, NSW Government, the Butchulla Aboriginal Corporation and the Plant Biosecurity Science Foundation.
ANPC Donation Drive – Will you help us in the fight against Myrtle Rust?
From Nov 2022 – April 2023 we are raising funds for our work on Myrtle Rust.
Myrtle Rust, an introduced fungal disease, is a major threat to Australia’s flora. It infects hundreds of species in the Myrtaceae family, which includes our bottlebrushes, paperbarks, lilly pillies, and eucalypts. Since this disease was introduced to Australia in 2010, at least five native plants have jumped straight to the ‘Critically Endangered’ category as a direct result of the disease, and are faced with extinction in the wild in the very near future.
A further 20 to 30 Australian native species are known, or suspected, to also be in decline, and over 300 more are known to be susceptible to a lesser degree. This number will rise.
These funds will be used to:
The ANPC has been at the forefront of the effort to fight Myrtle Rust since 2010.
Much of the ANPC’s work on Myrtle Rust until very recently has been on a voluntary basis or at best a shoestring budget.
We are currently coordinating a separate Commonwealth funded project to provide Safe Custody for Native Guava from Myrtle Rust. This pilot project, which lays the basis for a dispersed ‘metacollection’ of Native Guava, is the tip of the iceberg of what is needed.
We need to take our fight against Myrtle Rust to the next level.
Our Myrtle Rust team are happy to discuss our work with prospective donors.

Myrtle Rust Survey
The Council of Heads of Australian Botanic Gardens and BGANZ are running a Myrtle Rust survey. The survey will take stock of Myrtaceae species currently in collections across the country to inform future actions to conserve myrtle rust-affected species. If you or your organisation hold conservation collections of Myrtaceae species please complete the survey, any questions and the completed spreadsheet can be sent to Damian Wrigley at email@example.com

The Myrtle Rust global host list
Austropuccinia psidii the causal agent of myrtle rust disease (syn. Puccinia psidii, Sphaerophragmiaceae, Pucciniales) is one of the best illustration of an unusual broad host range rust fungi. This pathogen is affecting specifically the Myrtaceae, a family that comprises 142 genera and 5,500 species worldwide (Thornhill et al. 2015).
Establishing the complete list of A. psidii host range is challenging given its broad and continual expansion into new geographical areas and host species. In biodiversity hotspots such as Australia and New Caledonia, the myrtle rust has found a wide diversity of naive host species. Consequences of the encounter of A. psidii and new naive host resulted in a massive expansion of its host range. This list provides an update on the A. psidii global host list, including the recent host list released from New Caledonia and New Zealand. A total of 480 species and subspecies (up to 524 at the taxa level) were recognized as host of A. psidii. The scientific name nomenclature chosen for the genera, taxa, species, subspecies in this list, were extracted from the World Checklist of Selected Plant Families database (Govaerts et al. 2015), a unique and continuously updated synonymized world list of plants by the Royal Botanic Gardens of Kew. To keep consistency and track back the species in the literature, we also include in this list the species names as found in the original literature source.
