I just picked up on this thread, that farm is only a couple of kilomettres from here. I'm doing a site floristic survey near there, about 500m down the road.

Thanks for that information, will keep it in mind.

thought I should post this

NSW has declared a Quarantine Area on the Gosford and Wyong Local Government Areas (LGAs) effective Friday 23 July 2010 on account of the presence of Myrtle Rust within these LGAs.
As a result, the movement of:
1. any host plant material, and
2. any covering, packaging, machinery, or thing which is carrying Myrtle Rust and which has been used in the culture, harvesting, or packing of host plant material,
out of the Quarantine Area is prohibited subject to the consignment meeting the required movement conditions as stipulated in the notification.

Current situation summary
• Myrtle Rust has been found on the NSW Central Coast. It affects plants of the Myrtaceae family which includes many much loved native species.
• The state has put in place measures to contain and eventually eradicate the fungus.
• The Gosford and Wyong Local Government Areas (LGAs) have been declared a Quarantine Area, restricting the movement of susceptible plants and related material out of the area.
• Industry and the public are asked to learn how to recognise the fungus and report any suspected cases early, as well as practise good hygiene methods to restrict the spread of the fungus.

and the following article of what it affects and what to look for

Myrtle Rust found in Australian nursery

The plant disease Myrtle Rust has been detected in a cut flower growing facility on the NSW Central Coast.

It is the first time the disease has been found in Australia.

Rust diseases are highly transportable on clothes and shoes and are very hard to contain.

The Consultative Committee on Emergency Plant Pests set up by the Department of Forestry, Fisheries and Agriculture to provide technical advice has decided that the rust is not feasible to eradicate.

The National Biosecurity Committee will oversee continued surveillance and continue testing in order to assess the implications of Myrtle rust and develop options for its management.

Myrtle rust has been found on Agonis flexuosa (willow myrtle), Syncarpia (turpentine) and Callistemon (bottlebrush) species.

Dr Satendra Kumar, director of plant biosecurity at I and I NSW says the nursery at Wyee was placed in quarantine when the outbreak was discovered but has since been re-opened.

"There is just one property affected with a range of plants present.

"We don't know the real impact as this is different to other rust varieties in Australia and it has a very wide host range.

"It's not a fungus of cereal crops and it hasn't been found so far on Australian eucalypts. but Dr Kumar says it's too early to predict what impact it will have on the range of plants in nurseries.

"The taskforce will meet again at 2pm tomorrow (Wednesday 5th May), involving government agencies and research organisations, and they'll be looking at distinguishing this variety of rust from others already in Australia and at control options."

The department says myrtle rust is closely related to the rust fungus causing guava rust and is part of a complex of rusts that infect the Myrtaceae family of plants.

That includes many Australian native species.

Myrtle rust produces lesions on young, actively growing leaves and shoots as well as on fruits and sepals.

Leaves may become buckled or twisted as a result of infection.

On turpentine and callistemon, rust lesions are purple in colour, with masses of bright yellow or orange-yellow spores.

They typically attack young plants and new growth on established plants and can be controlled in commercial operations with the use of fungicides.
In this report: Dr Satendra Kumar, director of plant biosecurity at I and I NSW.

Introduction and establishment of Exotic Rust Fungi of the order Pucciniales pathogenic on plants of the family Myrtaceae - key threatening process listing.

One variant of the Puccinia psidii sens. lat. complex, Uredo rangelii, distinguished from P. psidii sens. strict. by morphological differences in the urediniospore stage, has recently arrived and naturalised in Australia, where it is referred to as ‘Myrtle Rust’.

2. The potential threat to the Australian biota of exotic rusts, other than those of the Puccinia psidii sens. lat. complex, is uncertain but all exotic myrtaceous rusts are to be considered part of this Key Threatening Process, and any rusts detected on myrtaceous species in Australia should be regarded as suspect and reported for prompt identification (see http://www.dpi.nsw.gov.au/biosecurit...e-rustexternal link).
