The Ministry for Primary Industries (MPI) has received test results confirming the fungal plant infection myrtle rust is present at a second site in Kerikeri.

The new infected property is a close neighbour of the original confirmed infected nursery, in the same Kerikeri street. It is a private residential property and not a nursery.

Earlier today MPI released information that a second nursery in Kerikeri was under suspicion of having myrtle rust, but laboratory tests on samples proved negative. MPI is now arranging re-testing of further samples, given the fact that the symptoms appear like myrtle rust and are on highly susceptible plants. Sometimes false positives can occur with PCR testing.

MPI’s Director Response, Geoff Gwyn says the new positive residential site is not unexpected, given the ability for myrtle rust to spread as invisible spores on the wind. There will be conditions placed on the property to prevent the spread of myrtle rust from this new site and affected plants will be treated.

Again, we can’t stress enough how important it is for the public and businesses to keep an eye out for the disease. Nursery, orchard and eucalyptus forestry operators in particular need to remain extra vigilant, especially when moving material from Myrtaceous species.

Advice for nurseries

Today, Project Crimson has been working to get advice for nurseries on what action they should take.

MPI have tracked down the stock that has gone in and out of the affected nursery and have not found any other infestations. There are currently no restrictions on movement of plants and MPI stated that the infestation at the original nursery has been contained.

The advice is to look for infestations on your own stock. If you find anything of concern, call MPI on 0800 80 99 66. They will send someone out to spray with a fungicide and advise further.

Remember, early detection is vital to any attempt to control myrtle rust. Full information including media updates, pictures and a fact sheet is at: www.mpi.govt.nz. If you believe you have seen myrtle rust on plants in New Zealand:

• Immediately call MPI on 0800 80 99 66

• Do not attempt to touch the plant as this may aid in the spread of the disease

• Take a clear photo of symptoms and the host plant if possible
