Phytophthora ramorum: a threat to Australia?
What makes Phytophihora cinnarnomi such a devastating plant pathogen in the Australian environment?
• It is a microscopic organism that lives in soil and plant roots.
• It can., and has, spread widely in many Australian landscapes through movement of infested soil from one location to another, naturally and by human activities ranging from bushwalking to mining.
• It can reproduce asexually and prolifically when conditions are optimal (warm and moist).
• It infects a very broad range of plants, and the susceptibility of much of Australia’s unique flora indicates that it is exotic in origin.
• Once present in a landscape it cannot be eradicated, although management is possible with commitment from governments, industry and the community.
It’s a fairly grim scenario...but it couldn’t get any worse. . .could it? Unfortunately, it could! Imagine a species of Phytophihora that has all the characteristics of P. cinnamonii, but also has the capacity to be carried by wind-driven rain. Phvtophthora rarnorum is just such a pathogen.
