Myrtle rust fungus confirmed in Bay

Posted at 1:19pm Tuesday 13 Jun, 2017

UPDATED 2.19PM: Myrtle Rust doesn’t affect kiwifruit or avocado plants, says Rotorua MP Todd McClay.

Todd has been given assurances by the Minister for Primary Industries Nathan Guy that MPI will do everything it can to manage the wind-borne fungus in the Bay of Plenty. 

“It is business as usual for kiwifruit growers who have recovered so well from PSA, but I recognise there will be some uncertainty for others including the Manuka Honey sector," says Todd.

“It’s obviously very disappointing that this wind-borne fungus has spread to the Bay of Plenty, but MPI will do everything within their power to manage this infection."

The infection was identified in residential garden in Te Puke and Todd says the fast diagnosis by the property owner will help efforts to contain the infection.

“I want to recognise that the property owner has done the right thing in identifying Myrtle Rust and promptly reporting the infection to MPI. 

“The faster MPI know about these infections the greater the chance it has of limiting its spread," says Todd. 

“We saw during the PSA outbreak just how resilient our growers and communities can be. I would again urge local people to show the same vigilance with Myrtle Rust and report any concerns as quickly as possible to MPI’s Biosecurity hotline on 0800 80 99 66.”


Laboratory tests by the Ministry for Primary Industries (MPI) have confirmed that the plant fungus myrtle rust is present in Te Puke in the Bay of Plenty. 

The infection has been found in a 25 year old ramarama plant in a private residential garden. It is the first find in a number of weeks outside of the key infection area in Taranaki.

Myrtle rust response Incident Controller David Yard says the new find is very disappointing. 

“We had thought that the incursion could be contained to the small geographical area around Waitara. While it’s too early to say what the new detection will mean in terms of the ongoing operation, it’s certainly not good news in terms of its distribution in New Zealand.” 

David says the property concerned has been placed under controls so that any movement of plant material or other risk goods from the property is stopped. 

MPI has a team removing the affected plant, spraying the area with fungicide and doing a thorough check of the garden. The team will also begin a concentrated survey of vegetation surrounding the find. 

“Our preliminary talks with the property owner have not found any obvious link with the situation in Taranaki or Northland, and there have been no recent nursery plant introductions to the garden. This lends weight to the possibility that this new location is a wind-borne infection.”

David says the Te Puke home owner is to be congratulated for being responsive and contacting MPI when she saw suspicious symptoms on her tree. 

“The public response to myrtle rust has been huge and gratifying. So far we’ve had 822 calls reporting suspected myrtle rust. It’s vital information. Building our knowledge of this issue and the distribution of the disease will enable us to make the best possible decisions about managing this into the future.” 

To date there are 46 known infected properties in New Zealand - four in Northland, two in Waikato, 39 in Taranaki and the one new find in Bay of Plenty.


I reckon it's Evolutionary

All we can do now is make the best of it and wait for it to diminish. Remember the big Cordyline Australis scare a few years ago? We saw many cabbage trees die, only to sprout anew later. Now it seems to have completely gone and the Cordylines are all healthy again. 1080 seems to be doing a great job too. Kaimanawas and Ruahines are making a spectacular recovery from tree-climbing pest damage. It’s evident as soon as you step under the canopy these days. Also the view from the tops is completely different with all that spindly deadwood gone. For a small nation we are really onto it. I’ll bet a pound to a knob of goatshit that Myrtle rust will be gone in a few years. We’ve seen this kind of stuff before.
Yeah, give it up

Same with pest eradication. Stop wasting money. The place is shot, like the rest of the planet. Stop kidding yourself. Pack it in and let’s go down in style.
Combating Myrtle Rust

The Caveman’s comments are likely correct. BOPRC should initiate a region wide alert through the media including online social links (facebook etc) for all households to check their property. The alert should include a full description plus guidelines on how/who to contact if the disease is found. Surely the PSA outbreak has taught BoP residents something, now its time to be pro-active against Myrtle Rust. Max Lewis Mt Maunganui.

snow in the south island so the desert rd will be closed
Sorry, but I would suggest

that Myrtle Rust is now every wide spread - its wind blown ! If there are some 40 odd identified sites, it’s the tip of the iceberg, so to speak. If there are 40 known sites, then there are probably another 400 sites that have not yet been identified !!
