The aim of this study was to verify the pre-infection process of Austropuccinia psidii (A. psidii) in the leaves of three phenological stages of Eucalyptus clones with different resistance levels. Plants from the hybrids of Eucalyptus urophylla × Eucalyptus grandis (E. grandis) with variable levels of resistance to this disease were used. The pathogen was inoculated in vitro on abaxial leaf discs of first, third, and fifth leaf stages and maintained under conditions suitable for disease development. Subsequently, samples from these discs were collected 24 and 120 h after inoculation and processed using scanning electron microscopy analysis.

The Action Plan was developed in 2018 in consultation with experts, stakeholders and the public. The intent of the draft Action Plan is to provide a guiding framework for a specifically environmental dimension to Australia’s response to Myrtle Rust – that is, the conservation of native biodiversity at risk.

    NSW Threatened Species Scientific Committee Conservation Assessment of Rhodomyrtus psidioides (G.Don) Benth (Myrtaceae) Rachael Gallagher, April 2018 NSW Threatened Species Scientific Committee Rhodomyrtus psidioides (G.Don) Benth (Myrtaceae) Distribution: NSW, Qld Current EPBC Act Status: Not listed Current NSW BC Act Status: Critically Endangered Summary of Conservation Assessment Rhodomyrtus psidioides was found to be eligible for listing as Critically Endangered under the BC Act 2016 under Clause 4.2 (equivalent to IUCN Criteria A3(e)). To be listed as threatened under Clause 4.2 the species must have experienced a population reduction of 80% (CE threshold) over three generations or 10 years (whichever is longer). The effect of Austropuccinia psidii (Myrtle Rust) infection on Rhodomyrtus psidioides is severe across the species entire range based on quantitative evidence from field surveys. A > 80% reduction in the population of R. psidioides across Australia over the three generations is reasonably expected given documented levels of mortality due to A. psidii infection and high susceptibility to A. psidii in both mature individuals and seedlings. Description and Taxonomy Rhodomyrtus psidioides (G.Don) Benth (family Myrtaceae) is described by PlantNET 2017 as a: “Shrub or small tree to 12 m high with brown scaly bark; young branchlets and inflorescences pubescent with pale hairs. Leaves with lamina narrow-ovate to elliptic or oblong, 5–25 cm long, 2.5–6.5 cm wide, apex shortly acuminate, base cuneate, upper surface glabrous and glossy, lower surface paler; lateral veins conspicuous, intramarginal vein absent; oil glands numerous and conspicuous; petiole 15–20 mm long. Flowers 5-merous, in cymes or raceme-like inflorescences; peduncles 10–25 mm long.

However, exact southern limit is difficult to ascertain as it has been widely planted and there is evidence that old time Maori cultivated the tree in some southerly areas. Found inland around the Rotorua Lakes and at Lake Taupo - though these occurrences could stem from Maori plantings (though the association of other normally coastal species around these lakes argues against this).

  • Rapid Field Assessments of Impacts of Plant Fungal Pathogen Austropuccinia Psidii on Five High Priority Myrtaceae Species in New South Wales, Australia
    Cunninghamia Date of Publication: March 2019 A journal of plant ecology for eastern Australia ISSN 0727- 9620 (print) • ISSN 2200 - 405X (Online) Rapid field assessments of impacts of plant fungal pathogen Austropuccinia psidii on five high priority Myrtaceae species in New South Wales, Australia Anthony Manea1*, Laura Fernandez Winzer1 and Michelle R. Leishman1 1Department of Biological Sciences, Macquarie University, North Ryde, NSW 2109, AUSTRALIA *Corresponding author: [email protected] Abstract: In 2010, the plant fungal pathogen Austropuccinia psidii was detected in Australia. It has since spread rapidly through the eastern states of Australia causing significant population declines in a number of susceptible species. However, there are still a number of potentially vulnerable species that lack the necessary field observations that are needed to accurately gauge the risk Austropuccinia psidii poses to them. Because of this, rapid field assessments of these species have been given the utmost priority. In the spring of 2018 (October) we carried out rapid field assessments for five high priority species. We did not observe active Austropuccinia psidii infection on any of the species at the time of assessment despite the majority of individuals having susceptible new flush. However, we did find evidence of significant previous infection (branch dieback) in the largest Archirhodomyrtus beckleri population we assessed. Therefore, to confirm our observations, it is necessary to re-assess this population when environmental conditions
