What is Phytophthora? • Water mould • Carried in soil and water • Depending on moisture • Not visible with the naked eye • More than 50 Phytophthora species worldwide • Phytophthora cinnamomi (Pc)is most common species and most destructive in Australia • Introduced into Australia from South-East Asia • Found in high rainfall areas • Very wide host range – ornamental plants, fruits, vegetables and native vegetation • Affects roots and stem of plants - causes them to rot and die

  3. Key threatening process • Pc has been listed under the Environment Protection and Biodiversity Conservation (EPBC) Act 1999 as a key threatening process: • Major threat to native vegetation and fauna • Many native plant species in Australia are endemic • National Threat Abatement Plan

Pc management • Temporary or permanent closureof roads and tracks • Program your work: • Plan your work around times when soils are driest • Work in uninfected areas first, then move into infested areas • Hygiene - ensure vehicles, equipment, footwear, bicycles and horse’s hooves are clean at all times! • Educate people • Guidelines, posters & brochures
