Myrtle rust disease
Myrtle rust is a serious fungal disease that affects plants in the myrtle family - eg pohutakawa, rata, swamp maire, kanuka, manuka, ramarama, feijoa, eucalypts and guava (the last three are exotics). A number of organisations are involved in safeguarding the myrtle species and dependent ecosystems, including the Department of Conservation, Ministry for Primary Industries, New Zealand Plant Producers Incorporated and Project Crimson.
There is no confirmed way to stop myrtles from contracting the disease, but there are some ways to give plants the best chance against it. We have a small amount showing on a small number of trees and we prune and monitor them very carefully.
