Progress in understanding Phytophthora diseases of trees in Australasia

Hardy, G., Burgess, T.ORCID: 0000-0002-7962-219X, Guest, D., Cahill, D. and Smith, I. (2010) Progress in understanding Phytophthora diseases of trees in Australasia. In: 5th IUFRO Phytophthora Diseases in Forests and Natural Ecosystems, 7 - 12 March, Auckland and Rotorua, New Zealand.


Since the 2007 meeting a number of new Phytophthora species have been described. A number of these appear to be associated with woodland and forest tree declines, but may have been misidentified in earlier work. These will be reviewed and updates provided. At least two ‘Fishing for Phytophthora’ activities have been undertaken and new Phytophthora species together with hybrid species are evident. Significant community driven projects are being undertaken in Western Australia and elsewhere relating to mapping, prioritisation of areas for hygiene and phosphite activities, effective communication to the wider public and initiatives to obtain on-going funding to Phytophthora management. Eradication and containment activities are now being put into practice in wild land communities in Western Australia. At the research level there are a number of applied and basic research studies on understanding, Phytophthora in nurseries and urban parklands and reserves, Phytophthora and fire, host resistance, the action of phosphite at a molecular and biochemical level, and how phosphite induces a phosphate starvation response in plants and possible implications. These research activities and more will be reviewed.
