Abstract
Taiwanese isolates of Phytophthora infestans were examined for mating types and pathogenicity to tomato and potato. A total of 70 isolates, including 68 isolates from tomato and 2 isolates from potato, from six counties of Taiwan were all Al mating type. Three tomato isolates of P. infestans caused only leaf blight of tomato, while two isolates obt ained from potato were able to cause the disease both on potato and to mato, indicating that host-specific strains of P. infestans occur in T aiwan.
