Pest Factsheet of Flowering Trees: Sudden oak death (Phytophthora ramorum)
Published: Mar, 26 Mar 2013, 16:23Last updated: Lun, 11 May 2015, 17:01
The pathogen Phytophthora ramorum causes the tree disease known in the USA as Sudden Oak Death. This pathogen is not present in Australia and should be considered an invasive species due to its ability to spread, persist, and reproduce in new environments. P. ramorum’s rapid life-cycle, ability to reproduce asexually, aerial biology and capacity to produce resting spores allowing it to survive through unfavourable climatic conditions are elements favouring this species’ potential invasiveness. The pathogen has a broad host range and although it causes a lethal stem canker on some trees, on other hosts it exhibits a non-lethal nature providing a source of spores for continuing dispersal.
