Willow Myrtle is grown for its habit and planted as a specimen tree along borders as a wind break and in second line coastal plantings. Viola species are infected by the rust (Puccinia violae) which forms green spots on the underside of the leaves. Senecio, Bellis and Calendula species are infected by the rust (Puccinia lagenophora) which forms blister-like pustules that release brown spores. It has a large representation in the Australian landscape. 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. Common plants that are susceptible to myrtle rust include: New host species in Australia are continuously being discovered.
