Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Text-Book of the Diseases of Trees Some fifty years ago a number of able investigators, of whom only Saxesen, Th. Hartig, and Ratzeburg need be named here, applied themselves to the study of insects. The life-history of forest insects, their harmfulness or usefulness, soon became the favourite study of many practical foresters, and in a few decades the joint efforts of numerous workers were rewarded by the elevation of Forest Entomology to the position of a much appreciated subject of scientific instruction, which has become the common property of all educated foresters. The case was otherwise with those plant-diseases which cannot be ascribed to the injuries of animals. Their investi gation was delayed until quite recently; for it was only after botanical science, by the aid of its chief instrument, the microscope, had obtained a clear insight into the normal strue ture and vital phenomena of plants, and especially after the study of fungi had been prosecuted in the last few decades by a series of distinguished investigators, that the examination of the phenomena of disease in the life of plants could be undertaken with a prospect of success.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Manual of Tree Diseases The steadily accumulating knowledge of the diseases of trees in the United States has never been brought together and made available to the general public. The intention of this Manual is to describe and suggest means of control for the tree diseases that have been most studied. Much remains to be learned about many of these diseases, and still many more have never been investigated. Therefore, in the treatment of this subject there are many unavoidable limitations which the trained reader will perceive. The diseases of fruit-trees, and of field and vegetable crops, have received the attention of plant pathologists in most parts of the country for many years. The results of these investigations have been made available to the growers of these crops in various ways. On the other hand, the diseases of forest, shade, and ornamental trees have been largely neglected until very recently. Tree diseases cause enormous losses in the large tracts of forests on which we depend for timber. The timber owner has been slow to adopt the fundamentals of scientific forest practice, and so far methods for the control of forest-tree diseases have not begun to operate in reducing losses. The owners of shade and ornamental trees are constantly confronted with diseases which they wish to control. They have become accustomed to controlling insects, but the fundamentals involved in the appearance of a disease and the measures necessary to protect trees from further damage are largely puzzling to them. An understanding of the cause of disease is essential to the undertaking of adequate control measures. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Text-Book of the Diseases of Trees The foundation of a science of Mycology by Berkeley, de Bary, and Tulasne, pursued by Brefeld, Zopf, and others, has led to a knowledge of the biology of fungi highly creditable to the industrious observers who have explored this domain of the vegetable kingdom; while the gradual building up of the science of plant-physiology from the days of Knight and Hales, De Saussure and Boussingault, to those of Sachs and Pfeffer, has placed us in possession of a vast amount of information as regards normal life processes in plants. Until much more recently, however, it cannot be said that we have had a science of the pathology of plants - i.e. the study of abnormal physiology - of anything like the same importance, in spite of the splendid and progressive attempts of Berkeley, Frank, and Sorauer to found one. In the particular department he has cultivated, Robert Hartig has succeeded in founding a plant-pathology really worthy of the name, and I would especially emphasize this, that his researches are so thoroughly elucidative of pathological phenomena, in that he studies not only the nature of the structural lesions and of the physiological disturbances consequent on these, but also the factors of the environment which throw light on the question.

Book excerpt: Excerpt from The Chestnut Bark Disease: Where Found in Massachusetts; How to Tell the Disease; Methods of Control; Trees Should Be Utilized Before They Die The chestnut bark disease was first recognized as a serious disease in the vicinity of New York City in 1904. Its origin is unknown, but there is some evidence that it was imported from the Orient with the Japanese chestnut. It is certain that it has now spread into at least 10 States.

Download or read book Diseases of Trees and Shrubs written by Wayne A. Sinclair and published by Ithaca, N.Y. : Comstock Pub. Associates. This book was released on 1987 with total page 584 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diseases of Trees and Shrubs is a comprehensive pictorial survey of the diseases of, as well as the environmental damage to, forest and shade trees and woody ornamental plants in the United States and Canada. An authoritative reference, it is also a reliable and handy diagnostic tool that will simplify the identification of specific plant diseases by focusing on signs and symptoms that can be seen with the unaided eye or with a hand lens. This long-needed book gives readers complete, up-to-date information in an easily understood and convenient way. Each of the 247 color plates faces a page of explanatory text covering the biology and ecology (including host and geographic ranges) of the disease-causing agents (pathogens), a list of key references (there are more than 2,250), and, in some cases, black-and-white illustrations of pathogens. Selected information about biological and cultural control is provided. Scientific terms other than Latin names of pathogens are used only when necessary, and a glossary of terms and a comprehensive index are included. The color plates contain more than 1,700 illustrations of the diseases and injuries that some 350 biological agents and environmental factors cause to more than 250 species of plants. The book also serves as a guide to hundreds of other diseases related to those shown. The authors have used three levels of organization for this book. At the first level, diseases caused by biological agents are separated from those caused by environmental stimuli. At the second level, most diseases are grouped according to the plant part affected: leaves, twigs, limbs, roots, trunks, or the entire plant. At the third level, diseases are presented according to the taxonomic relationships among the pathogens. For this major project, the authors examined and photographed diseases and environmental damage in the field, visiting more than 50 states and Canadian provinces. Their book reflects the most important developments in fungal biology and taxonomy, plant bacteriology, virology, and environmentally induced stress in plants. It summarizes information about newly discovered diseases and provides up-to-date accounts of olds ones. Diseases of Trees and Shrubs can be profitable reading for anyone whose technical training does not extend beyond general biology, yet will also be informative to advanced students and plant pathologists. It will be welcomed by agricultural and horticultural advisers, plant inspectors, arborists, nursery professionals, landscapers, foresters, and urban planners. Wayne A. Sinclair is a Professor of Plant Pathology, Howard H. Lyon is Biological Photographer (retired), Department of Plant Pathology, and Warren T. Johnson is Professor of Entomology, all at Cornell University.
