Both authors have for more than two decades conducted research on a general defense system in plants against pathogens. Our efforts have focused primarily on the induction of this defense system, the hypersensitive reaction (HR), by plant pathogenic bacteria. Nevertheless, it is clear that HR is operative in plants infected by viruses and fungi as well. We propose to describe this phenomenon as it develops across the broad array of host-pathogen interactions. The historical aspects, biochemical-physiological, ultrastuctural and specific genetic factors implicated in the induction and development of HR are defined in some detail. We summarize our understanding of how HR proceeds, based primarily on data from research conducted on bacterial elicitation of the phenomenon. Finally, a number of unsolved basic questions pertinent to the induction and development of HR remain, and these will be delineated.
Compendium of Wheat Diseases and Pests, Third Edition is the definitive publication on diseases of wheat, completely updated since the previous edition published in 1987. Twenty years of advances and new discoveries about wheat diseases are delivered in this new edition, making it the largest compendium ever in the series. More than 70 contributing plant pathologists and entomologists, all experts in their fields, have contributed to this authoritative compendium. A new section on major insect and mite pests of wheat has been added to make this a truly comprehensive reference. This new third edition is re-designed to be easier to use than ever before. It incorporates 50% more images integrated with the corresponding descriptions of disease symptoms, causes, life cycles, and control practices.
Part I addresses the links between crop diseases and irrigation water. It describes water sources, recycling, and distribution systems and assesses their risk in exposing crops to waterborne plant pathogens. It also discusses specific plant pathogens found in these systems. Part II examines the diversity and biology of plant pathogens in water. Part III covers the latest technologies and methods for detecting and quantifying plant pathogens in irrigation water. Parts IV and V present an array of strategies and tactics for risk-avoidance and mitigation. These can be implemented at any point in business development, from land purchase to production system design and in-season management—and at different points in the system, from runoff containment basins to pump houses and production beds. Part V addresses pathogen management through good system design and the application of best practices.
This comprehensive book does more than provide the most current disease and pest information for commercial and non-commercial growers throughout the world. It provides it in a simple, easy-to-use format that helps readers quickly recognize and control pest-related problems of these valuable and beautiful plants. The Compendium of Rhododendron and Azalea Diseases and Pests, Second Edition is an essential tool for gardeners, commercial growers, consultants, and others who cultivate these plants in commercial nurseries, home gardens, park and municipal landscapes, and similar settings. It is also a useful reference for students, plant scientists, and extension experts working in entomology, plant pathology, horticulture, nematology, and related disciplines.
More than 90 plant pathology experts have collaborated to update one of the most popular APS PRESS Compendia of all time. Compendium of Corn Diseases, Third Edition is completely rewritten and includes more than twice the information as the previous edition. This guide is the most up-to-date resource available for identifying and controlling diseases and disorders of corn. Everything is new, with special attention given to updating symptoms, pathogen descriptions, literature citations, and newly important diseases. With 177 color photographs, nearly all of them new, the third edition offers more than twice the color images as before. State-of-the art color reproduction and high quality detailed images make this a must-have resource for anyone working with corn.
This comprehensive book examines how mineral nutrition affects plant disease. Minerals improve the overall quality and health of plants. Knowing how each individual mineral affects a plant is beneficial for efficiency in production and sustaining the ecosystem. From a plant pathology perspective, Mineral Nutrition and Plant Disease brings the discussion of plant disease diagnosis and management to a new level. Mineral nutrients are important in production agriculture and horticulture because they can often be the first line of defense against plant diseases. It is an area of knowledge that can be misunderstood or overlooked in the study of diseases and their diagnosis. This reference succeeds in organizing what we know and explaining the interactions at work. Mineral Nutrition and Plant Disease is the first book to successfully combine two important plant science disciplines, nutrition and pathology, to provide current information on theoretical aspects of nutrition in disease physiology while contributing a wealth of basic practical information for obtaining immediate disease suppression with specific fertilizers.
Illustrated Genera of Imperfect Fungi, Fourth Edition is an update of the classic reference that mycologists and others interested in imperfect fungi have relied upon for decades. It provides comprehensive information for recognizing, identifying, and learning various aspects of the reproductive and somatic morphologies of imperfect fungi. Its practical use in the identification of imperfect fungi makes it an essential tool.
Citrus Tristeza Virus Complex and Tristeza Diseases is a comprehensive title on controlling and managing citrus tristeza virus (CTV), which causes complex disease syndromes in citrus. This book includes a description of the disease and its history as well as information about diseases caused by the virus and the management of the disease in different countries. This book will be of interest to plant pathologists, plant virologists, horticulturists, and graduate students in plant pathology and related sciences.
Section one addresses the commonly occurring infectious fungal diseases of alfalfa, grouped by leaves and stems, lower stems and crowns, and crowns and roots. This section also provides information on bacterial and mollicute diseases, diseases caused by viruses, and those caused by nematodes. The parasitic flowering plant dodder is also discussed. Section two covers arthropod (insect) pests, detailing their life cycles, damage, identifying features, and management. This section describes arthropods that feed on foliage, including many kinds of aphids and caterpillars, crickets, grasshoppers, leafminers, plant bugs, spittlebugs, and weevils. Root and seed pests are given special sections, as is a livestock pest, the blister beetle. Section three, titled ‘Noninfectious Diseases and Abiotic Conditions,’ discusses the effects and management of genetic variations and abnormalities, herbicide injury, high-temperature flooding injury, nutrient deficiencies and toxicities, foliar freeze injury, and winter injury. The appendix presents an updated list of common names of diseases of alfalfa caused by microbes, nematodes, and viruses, as well as arthropod insect pests of alfalfa.
Celebrating the 100th Anniversary of virology, Tobacco Mosaic Virus: One Hundred Years of Contributions to Virology is an anthology of this past century`s classic papers written about tobacco mosaic virus and its impact in the field of virology and related studies. A historical perspective shows an appreciation for this important virus and how these classic experiments have led to our current understanding of all types of viruses today.
