A diagnostic guide for myrtle rust

Abstract

Myrtle rust is associated with more than 480 host species belonging to the Myrtaceae family, including economically important genera, such as Eucalyptus, Metrosideros, Angophora, Syzygium, and Psidium, and native plant species that are part of forest biodiversity in several countries (Soewarto et al. 2018). This disease is caused by Austropuccinia psidii (G. Winter) Beenken, 2017 (Synonym Puccinia psidii (G. Winter), 1884). In this publication we provided methods for myrtle rust diagnosis and to manipulate the pathogen in field and laboratory conditions.
