Available in PDF, EPUB and Kindle. Book excerpt: A 4-year-old Douglas-fir plantation in the western Washington Cascades was monitored for 8 years after fertilization with potassium (K), nitrogen (N), and K+N to determine fertilizer effects on rates of mortality from laminated root rot (LRR) and other causes relative to a nonfertilized control. Each element was applied at a rate of 300 lb/acre on and around 0.2-acre plots replicated seven times in a randomized complete block design. Cumulative mortality from LRR did not differ significantly among fertilizer treatments, and losses were strongly related to density of infected stumps from the previous stand (r2 = 0.74). Mortality from disease and other sources accelerated during the 8 years of monitoring. Average tree growth and stand volume were greatest in treatment N and were reduced where N was combined with K. Continued monitoring is needed to identify potential longer term effects of the fertilizer treatments on susceptibility of Douglas-fir to LRR and Armillaria spp.

Available in PDF, EPUB and Kindle. Book excerpt: Laminated root-rot, caused by the fungus Phellinus weirii, is a serious root disease affecting Douglas fir and other commercially important species of conifers in north-western North America. This report provides an overview of the disease as it occurs in the Pacific Northwest of the US and Canada. Information is presented on recognizing crown symptoms and signs of the disease. The disease cycle of laminated root-rot from initiation to intensification and distribution within infected stands is also described. Finally, disease management strategies during stand development and at stand regeneration are discussed. Features on the nomenclature of the fungus and on its management by silvicultural and mechanical approaches are included.

Book excerpt: Excerpt from Laminated Root Rot of Douglas-Fir in Western Oregon and Washington It is important primarily as a killer. Young infected trees seldom survive long enough for reduction of growth rate or extension of decay into the butt log to be of much consequence. In old-growth stands, where killing is slower, infection is less common, and decay usually extends only a few feet into butt logs and involves mostly the low-quality core. This paper summarizes results obtained during the past 20 years from research still in progress. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
