Myrtle rust infections up to 41


The number of Myrtle rust infections found across the country has grown to 41, the vast majority being in Taranaki.
Northland now has four infected properties, the King Country has two and the remainder of 35 are in Taranaki.
Two Northland properties were found to have plants from the Kerikeri nursery where the original infections were first found in early May, and two more properties were discovered on Tuesday.
The affected plants have been removed and safely destroyed, the Ministry for Primary Industries says, and it’s still trying to contain the spread.
The disease has so far been found on ramarama, pohutukawa, eucalyptus, Lilly Pilly and manuka plants, but no cases on feijoa trees have been reported, MPI says.
Myrtle rust attacks native trees and could cause serious damage to manuka trees used in honey production.
There is no known method for controlling it in the wild, other than applying fungicide in very small areas. NZN
