    Eucalyptus marginata (jarrah) varies in its resistance to colonization by the introduced pathogen, Phytophthora cinnamomi. This trait has been exploited to yield jarrah clones ranging in resistance to P. cinnamomi. However, isolates of P. cinnamomi vary in their capacity to induce disease in resistant jarrah clones, with no association between pathogenicity levels and either A1 and A2 mating types or isozymes types. We have shown that isolates differ in their capacity to colonize jarrah and marri (E. calophylla) tissue. Disease outbreaks in jarrah, other native vegetation and horticultural crops due to P. cinnamomi are more likely to occur in warm moist conditions. These factors raise questions about the interactions between the pathogen, hosts and temperature, and consequent disease development.
