由Puccinia psidii引起的番石榴锈病可导致桃金娘科Myrtaceae多属植物发病。在巴西,苗圃和桉属Eucalyptus部分种类的幼苗严重遭锈病侵染,阻碍生长。在澳大利亚,有几百种桉属植物,许多是重要木材种类,具较高应用价值。作为防止锈病传入的一种措施,澳大利亚禁止下列各属植物和种子进口:红千层属Callistemon、桉属Eusalvptus、番樱桃属Eugenia,白千层属Melaleuca,杨梅属Myrcia,水柏枝属 Guava rust caused by Puccinia psidii can lead to the onset of many Myrtaceae species in Myrtaceae.
