This small tree has rough brown bark with multiple trunks that branch out into a graceful weeping crown. Similar to the myrtle rust infection detected in some Chilean guava plants (Tazziberry TM), it is highly likely that the infection in Agonis flexuosa is due to cross-contamination from infected . The response was unsuccessful because myrtle rust spores are very easily dispersed by wind. This low growing bushy weepingshrub has dark purplish foliage and produces white scented flowers during spring. Bottom heat is obtained from thermostatically controlled heating cables that are running under the media. Preventative measures can be taken to reduce the chance of myrtle rust being introduced onto properties, into unaffected plant communities or even in backyards. These cuttings are prepared during the dormant season from late autumn to early spring and are made up from previous season's growth.

On the underside of the leaf, corresponding to the patches, yellow orange spores form. It was suspected that these symptoms were caused by an opportunistic pathogen and a sampling strategy was designed to investigate the causal agent of the cankers in symptomatic trees and the presence (or absence) of this pathogen as an endophyte of asymptomatic trees . This leads to a loss of vigour in the plant and infected plants transmit the fungus. The main Myrtaceae plants infected with myrtle rust wereLophomyrtus x ralphii varieties (especially 'Black Stallion') and Willow myrtle (Agonis flexuosa 'Nana'). hbbd```b``S@$%d"vE.I[0Dr:H4%&S&HFW`v YfMlnl'XH~a`l#L ] Agonis flexuosa is naturally found in south-western Western Australia growing in coastal regions and in Jarrah forests from Perth to Albany.
