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.

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.

Urban trees on the prairies are essential to our changing landscape environment. I have helped thousands of people with their tree problems over the past 43 years. Tree diseases and how to deal with them continue to plague a very large number of people. "Where can we get more information about these tree problems?" is a question I am constantly being asked. This book will help you to narrow the search for the problems plaguing your trees by going through the images and accompanied text. As well, there are also helpful detailed instructions on how to take care of the nutritional requirements of your trees. Keeping a tree healthy can reduce its susceptibility to diseases much as good nutrition does with people and animals. You can always reach me on line at www.treeexperts.mb.ca if you need any further help. Enjoy your trees!

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.

This revised edition maintains the clear, nontechnical format of the first, and covers the infectious diseases of shade trees, the major pathogens that cause them, and noninfectious diseases and their agents. Special topics include nonpathogenic conditions, disease diagnosis, and tree injection and implantation. Comprehensive disease control protocols, a detailed discussion of disease diagnosis, and tree diseases of the western and southern United States are among the useful additions to this widely used text and reference. This is an essential book for arboriculturists and students of aboriculture.

The book is intended to provide comprehensive introduction to the important aspects of the field of forest pathology and tree diseases. The book is arranged in two major parts. The fundamental chapters, present forest diseases, pathogens, epidemics, and management that is applicable to all forest trees. The applied chapters on the individual crops that are grouped alphabetically present information on the symptoms, pathogen and integrated management of major diseases of forest trees. It was designed to give a broad overview of the field of forest pathology but with sufficient detail that they will be able to assess their specific role as practicing forestry professionals. Note: T& F does not sell or distribute the Hardback in India, Pakistan, Nepal, Bhutan, Bangladesh and Sri Lanka.
