Separation of Two Ecotypes of Phytophthora Drechsleri Tucker Occurring in Australian Native Forests

Abstract

A total of 70 isolates of P. drechsleri from Australian native eucalypt forests were separated into two distinct ecotypes. The "northern" ecotype occurred from North Queensland to the south of New South Wales, while the "southern" ecotype occurred in South Australia, Victoria, Tasmania, and New South Wales.
