Download Puccinia psidii on Nursery Stock - Risk Analysis (July 2011)

This document is an analysis of the risks associated with the rust fungus Puccinia psidii entering New Zealand via the myrtaceous nursery stock import pathway; it includes an analysis of the efficacy of risk management options. P. psidii causes rust disease, known variously as guava rust, myrtle rust, eucalyptus rust or ohio rust, of a wide range of host plants in the family myrtaceae. As New Zealand has myrtaceous species of economic, environmental and socio-cultural importance, P. psidii is considered to be a risk organism on myrtaceous nursery stock.
