| Summary: | The host and geographic range of the pitch canker pathogen has greatly increased since
it was first discovered in California in 1986. Most significantly, it now affects
many pine species, including native stands of Monterey pine, and has made a transgeneric
jump to Douglas fir. Isolated occurrences of the disease have been found as far north
as Mendocino County. Insects are strongly implicated as vectors of the pathogen, and
long-term management appears to be dependent on the development of resistant tree
varieties. In infested regions, the planting of Monterey pine and other pine tree
species should be undertaken with caution. |
