Phytophthora root rot, a form of 'dieback', is a disease that affects many native plants and ecosystems, important crops and horticultural plants in Australia and throughout the world. Its global spread has been the consequence of trade and human migration.
In Australia, the disease infects an especially large range of mainly woody perennial plant species and is also a major threat to some rare and endangered species.
