Has myrtle rust been found on manuka ?

@kaihoka  yes it has been detected infecting manuka in NZ and in testing of NZ seedlings in Australia.

Grant Smith from Plant & Food is looking for resistance in manuka and he has identified some resistance traits. For instance some plants are infected on stems and not leaves.

Other plants have demonstrated resistance. This is very valuable work, but to date it has only been tested on seedling plants and in the Lab.

Grant Smith expects to find resistant manuka plants that can be cloned for planting out which will be great, but he has a lot more research to undertake before he claims he has the answer to our future.

Here is his presentation at the Myrtle Rust symposium. https://www.bionet.nz/assets/14.-Grant-Smith.pdf

Once identified they should report it to iNaturalist website - https://www.myrtlerust.org.nz/what-to-do-if-you-find-myrtle-rust/

We are only in year 3 of a biosecurity incursion that has no known successful control. The prognosis is that things may get a lot worse than they are now.

Was'nt a Manuka blight introduced into the N. Island years ago in an effort to control the spread of the manuka ... only the scrub was too vigorous .

Meanwhile, down here the blight is alive and well and every so often sweeps through our patch on the farm with a sooty mould  .... killing it.
