Eucalyptus rust or guava rust is a serious disease caused by the fungus Puccina psidii. This pathogen is very unusual in that it has a very wide host range in the plant family Myrtaceae, which includes about 3000 tree and shrub species—many of which are of great economic and conservation significance. Plants native to Australia that are known to be susceptible to this disease include eucalypts (Eucalyptus and Corymbia), bottlebrush (Callistemon) and paperbark (Melaleuca).
