Certain cultivars are more susceptible than others, particularly 'Orange Drops' and 'Novella'. as the traditional and original owners and continuing custodians of this land, and acknowledges Elders past, present and emerging. Similar to the myrtle rust infection detected in some Chilean guava plants (TazziberryTM), it is highly likely that the infection in Agonis flexuosa is due to cross-contamination from infected Lophomyrtus plants, which were detected and subsequently treated in March 2015. Sowing seeds in a flat or germinating bed, through which seedlings are pricked-out then, transplanted into another flat with wider spacing or directly to an individual pot. The rust was first detected on common guava and lemon scented gum in South America but now is considered a native of South and Central America. Vascular - Exotic.
