Two hundred Pinus muricata trees, located within a native forest near Monterey, California, were inoculated with the pitch canker pathogen. Treated branches were removed 10–13 weeks following the initial inoculation, and the lengths of the lesions that developed at each of the inoculation sites were measured. Results indicated that bishop pine exhibits a wide range of variation in susceptibility to pitch canker disease. Of the trees that received only one inoculation, 27% showed almost no lesion development, indicating that they were relatively resistant to the pathogen, while others had significantly longer lesions and thus were more susceptible. Clonal propagation and seed collection from resistant individuals may offer useful strategies for disease management in the future.
