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.

Download or read book Westcott s Plant Disease Handbook written by R. K. Horst and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1242 pages. Available in PDF, EPUB and Kindle. Book excerpt: It was a compliment to me to be asked to prepare the fourth edition of Westcott's Plant Disease Handbook, and the decision to accept the responsi bility for the fourth edition and now the fifth edition was not taken lightly. The task has been a formidable one. I have always had a great respect professionally for Dr. Cynthia Westcott. That respect has grown considerably with the completion of the two editions. I now fully realize the tremendous amount of effort expended by Dr. Westcott in developing the Handbook. A book such as this is never finished, since one is never sure that everything has been included that should be. I would quote and endorse the words of Dr. Westcott in her preface to the first edition: "It is easy enough to start a book on plant disease. It is impossible to finish it. " This revision of the Handbook retains the same general format contained in the previous editions. The chemicals and pesticides regulations have been updated; a few taxonomic changes have been made in the bacteria, fungi, and mistletoes; the changing picture in diseases caused by viruses and/or viruslike agents has been described. A few new host plants have been added, and many recently reported diseases as well as previously known diseases listed now on new hosts have been included. In addition, photographs have been replaced where possible, and the color photograph section has been retained.

Download or read book Brown Leaf Spot and Cercospora Leaf Blight of Cassava written by James Mneesi Teri and published by . This book was released on 1978 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Cercospora or Cercospora-like diseases of cassava have historically been considered economically unimportant, although there were no experimental results to substatiate this view. This widely held but unsubstantiated view has hindered any serious work on these diseases. Therefore, to guide any future work on these diseases it is first necessary to establish their economic importance. The symptomatological, morhological and cultural characteristics which can be used to identify the four species inciting these diseases in cassava are presented, followed by the studies to elucidate the epidemiology and importance of brown leaf spot and Cercospora leaf blight. This study was conducted in twoinportant cassava-growing regions of Colombia, South America. The results indicate that brown leaf spot and Cercospora leaf blight are typically compound interest diseases with a long lag stage and a comparatively short logarithmic stage.

Download or read book Pseudomonas Syringae Pathovars and Related Pathogens written by K. Rudolph and published by Springer Science & Business Media. This book was released on 1997-06-30 with total page 714 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last decade, research on Pseudomonas syringae pathovars and related pathogens has progressed rapidly, opening up many new avenues. The application of molecular genetics has provided new insights into determinants of pathogenicity and virulence. Progress has also been made in elucidating the chemical structures and modes of action of phytotoxins from Pseudomonas syringae; by establishing novel strategies for disease control; in biotechnological applications; by studying the resistant reaction of the plant with a combined biochemical and genetic approach; and in the development of new detection and identification methodologies as tools in epidemiological studies. With such rapid advances it becomes more and more difficult to keep abreast of the developments and concepts within disciplines, all involving research on pathovars of P. syringae. In an attempt to provide a balanced overview, recent developments in these rapidly expanding fields have been critically reviewed at the beginning of each chapter by internationally renowned experts. Our comprehensive coverage has been made possible because all the contributors to this volume presented their latest findings at the `5th International Conference on Pseudomonas syringae Pathovars and Related Pathogens' in Berlin, September 3-8, 1995. In this way, it was possible to bring together contributions from a wide range of fields including phytopathology, genetics, bacteriology, plant breeding, plant protection, and taxonomy. This book is not intended simply as a record of the proceedings of the Berlin Conference, but as an extension of recent findings and hypotheses put forward at the meeting. All papers published in this volume have been reviewed by the Editors.

Download or read book Diagnosing Hemp and Cannabis Crop Diseases written by Shouhua Wang and published by CABI. This book was released on 2021-08-18 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hemp and cannabis, both belonging to Cannabis sativa, have emerged as some of the most valuable crops because of their multiple functionalities - industrial, medicinal, and recreational uses. Like all other crops, they are at risk of diseases and pests. In certain cases, an entire hemp field can fail due to unexpected disease. As a new and highly regulated crop, research on Cannabis crop diseases is scarce, and the science of plant diagnostics is not well covered in the literature. Taking hemp/cannabis as a model crop, the book illustrates how to diagnose a disease problem and how to manage it effectively. It presents real disease cases encountered during crop production, and explains methods of diagnosis, both in the field and in the lab, in order to find out the cause(s).
