Diseases of Western White Pine other than Blister Rust

Western white pine (Pinus monitcola Dougl.) is a valuable, fast-growing coniferous species of the Pacific Northwest. It reaches its greatest productivity and abundance in the Inland Empire, particularly in northern Idaho. Although this species can be productive on many sites, and is highly prized by wood-using industries, it is beset with serious diseases. Blister rust is by far the most important disease, causing extensive losses each year. However, several other diseases including pole blight, root diseases, and needle blights and casts can also cause serious damage. Important diseases of western white pine are listed in table 1. The most important of these, with the exception of blister rust, will be discussed.
