Phytophthora multivora P.M. Scott & T. Jung 2009
This oomycete is has been recorded in various regions. For example, it has caused serious diseases on broad-leaved trees like eucalypts in parts of Australia. The symptoms include rotten roots, internal wood discolouration, wilting, necrosis and dieback.
On Eucalyptus gomphocephala, P. multivora is highly aggressive, resulting in the progressive loss of fine roots and in drought stress during the summer, especially in sandy soils. In such environments it can cause high mortality. In other ecosystems, e.g. in South Africa, it has been often found without causing obvious disease symptoms (Jung et al., 2018).
