Taxonomy of Phytophthora fragariae var. fragariae and var. rubi
In September 1991 EPPO has changed its A2 quarantine list to the effect that Phytophthora fragariae had been subdivided into P. fragariae var. fragariae and P. fragariae var. rubi (EPPO A2 quarantine pests). A scientific report on the separation (Wilcox et al., 1993) has now been published describing the differences between the two varieties of Phytophthora fragariae.
