The state of Phytophthora science and management in natural ecosystems is Australasia

Hardy, G. and Williams, N. (2012) The state of Phytophthora science and management in natural ecosystems is Australasia. In: 6th International Union of Forest Research Organisations,IUFRO Working Party 7-02-09, 9 - 16 September, Córdoba, Spain.


Since the last IUFRO held in New Zealand 2010 there has been significant activity with regards to research and management of Phytophthora species in natural and peri‐urban forest, woodland and heathland ecosystems in Australasia. For example, numerous new Phytophthora species have been described with a number of others in progress. There are numerous stable hybrid Phytophthora species being found and questions are being asked about their role in natural ecosystems. Nurseries continue to play a role in the dissemination of Phytophthora species. Containment and eradication of P. cinnamomi at a management level has occurred for the first time in a range of diverse plant communities and varying soil types in Western Australia. This clearly shows that eradication is a viable option, although good hygiene measures still remain extremely important in reducing spread into disease‐free areas. The sequencing of the P. cinnamomi genome has been completed. Research is on‐going on determining how phosphite induces defence mechanisms in plants at a molecular and biochemical level. The interaction between drought and P. cinnamomi is being studied, particularly with regards to projected warming and drying in the next few decades by all climate models for southern Australia. Community engagement and participation remains high, although on‐going funding remains an issue and will be one of the challenges for the future. These activities clearly indicate that Phytophthora diseases still remain a key concern in the Australasian context. These and other activities will be addressed in more detail at the meeting in Spain.
