Available in PDF, EPUB and Kindle. Book excerpt: S2The root rot caused by the fungus Fomes annosus is a serious threat to coniferous plantations throughout the North Temperate Zone. It is especially prevalent in plantations that have been thinned; and it commonly spreads through the roots from diseased trees to healthy news. In 1962-67 we conducted a series of experiments to provide preliminary information for testing the hypothesis; that a continuous band or zone of roots rendered unsuitable for invasion by F. annosus will prevent the underground spread of this fungus from diseased to healthy trees.S3.

This book was released on 1968 with total page 680 pages. Available in PDF, EPUB and Kindle. Book excerpt: S2In a study carried out on the George Washington National Forest, 72 of the existing 143 site-stand condition classes were designates as candidates for timber-stand-improvement or conversion projects. But which projects are worth undertaking, and which should receive priority? These are decisions that confront program administrators and forest managers alike. To help them in this we have made investment analyses of the 19 most prevalent (modal) project classes, which together encompass almost 124 thousand acres of this Forest in Virginia and West Virginia. By providing a basis for rating and comparing opportunities, these appraisals suggest what kinds of projects to favor in planning an efficient program for stand improvement and stand conversion.S3.

Book excerpt: Tree Pathology: A Short Introduction is a compilation of texts about some of the significant stress factors that are capable of inducing tree injuries and diseases. It also provides an overview of some of the examples of the damage caused by each stress factors or agents. In addition, existing hypotheses related to the mechanism by which each agent causes abnormal tree physiology are reviewed. As an introduction, the book provides a discussion on the agents, mechanisms, and control of the pathological stresses of forest trees. It also offers specific examples of forest tree species, mostly from the northeastern portion of the United States, as well as examples of citrus and other fruit or jut tree species. The book then discusses all injury and disease agents including their taxonomy, morphology, physiology, and ecology. It also presents the different mechanisms of the injury and disease, control possibilities on mitigating disease influences of plants, and specific utility of the various procedures used in forest tree disease control. The materials presented in the book are based from the numerous published texts, journal articles, and research reports.
