In a domestic garden small plants such as Fuchsia species may be sprayed with a protectant chemicals as symptoms appear, aided by the removal of existing infected leaves. Cultivars of Lophomyrtus all have a similar look but will differ with each having distinctive variegations in leaves and stems, with colours ranging from light green, through to red, dark red, brown, crimson and black(Images by DPIPWE/S.DeSalis).

Sorbus aucuparia is affected by several rust from the (Gymnosporangium species) causing circular yellow spots, that appear on the leaves during summer and develop into orange cup-shaped fruiting bodies. This overall, results in a loss of vigour and in small plants may lead to death. Vascular - Exotic. Pustules fade to dull yellow and then grey as the infection ages. Equal parts of sand and peat moss have good results for cuttings, which are left for a period of time to allow the roots to form. Spores are spread by wind to other host plants. The underside of the leaf develops pale yellow fruiting bodies. It has a low water requirement once established. Myrtle rust was detected on Agonis flexuosa (common name: Willow myrtle, with varietal names including "After Dark") at a nursery that was treated for the disease.. Senecio, Bellis and Calendula species are infected by the rust (Puccinia lagenophora) which forms blister-like pustules that release brown spores. columbianus) which is regarded as a sub-species of the Mule deer.
