Phytophthora (Root Rot)

Phytophthora Root Rot or Phytophthora cinnamomi, as it is scientifically known, is an introduced pathogen that attacks the roots of susceptible plants. In some native plant communities, epidemic disease can develop, causing the death of a large number of plants.

In Tasmania, the vegetation types most affected are heathland, moorlands, dry sclerophyll forest and scrub.
