Book excerpt: Excerpt from Elytroderma Disease of Ponderosa Pine in the Pacific Northwest Weir's (19162) observations in 1913-15 were evidently made during the waning stages of an extensive outbreak that had started many years before. Damage from this or possibly a later and less extensive outbreak continued for several years in parts of southern Idaho. In Oregon and Washington during the 1920's and 1930's, large brooms (presumably relics of the outbreak described by Weir) were fairly common in some localities, but no damage was observed even where Weir had recorded the disease as destructive. The current outbreak first attracted attention in 1945 in central Oregon. Dur ing the next few years, the disease was found to be occasional to common in stands of all ages throughout the region. Evidence to be presented later indicates that a heavy wave of infection occurred in the late l93o's or very early l94o's. Some subsequent infection by spores has occurred from time to time.

This book was released on 1981 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: A disease of Jeffrey pines (Pinus jeffreyi Grev. and Balf.) at Lake Tahoe Basin, California, caused by Elytrodenna disease (Elytroderma deformans) was studied for 7 years after a severe outbreak of the fungus in 1971. Among 607 Jeffrey pines on six plots, about one-half were heavily infected and about one-half were moderately or lightly infected in 1971. No uninfected trees were observed. During the 7-year study, about one-half of the trees remained unchanged in vigor, disease intensity, or both, and about one-half decreased in vigor, became more heavily infected, or both. Of the original 607 trees studied, nearly one-third died before 1978. Average radial growth of surviving trees was less per year after the outbreak than before, and heavily infected trees were growing more slowly than lightly infected trees. Intensity of the disease, however, was not related to stand basal area.

This book was released on 2018-05-06 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Red Rot of Ponderosa Pine in the Southwest Living branches are sometimes infected when the red rot fungus attacks dead secondaries, and the rot may eventually extend into the trunk through the branch heartwood, if present, or, in rare instances, through the living sapwood in truly parasitic action. Except in large and long-lived branches, however, these infections make little progress before the branches die and new infections occur closer to the trunk.
