This clearly written book is an ideal entry-level text for inquisitive college students who are majoring in a subject other than plant pathology, especially those in general education and core science classes. There is a student resources website organized around the book’s topics that will help bring the stories of plant diseases to life through podcasts, exercises, and other teaching tools. For those teaching with this book, there is an instructor’s-only web interface with resources that will be your course guide throughout the semester. If you wish to build a course around Hungry Planet, these award-winning educators have already done the preparation work for you—it is only a click away on APSnet. Anyone who has taught a course with Schumann’s earlier book, Plant Diseases: Their Biology and Social Impact will find Hungry Planet to be an amazing update of one of the perennial favorites among APS PRESS books. 

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.
 

Covering the key techniques used when working with fungal plant pathogens, this practical manual deals with recognition of disease symptoms, detection and identification of fungi and methods to characterise them well as curation, quarantine and quality assurance.The book is unique in its practical focus, providing an overview of both traditional and emerging methods and their applications, and detailed protocols on completion techniques such as microscopy, PCR, ELISA, freeze drying and DNA storage. Fungal Plant Pathogens provides a valuable guide to investigating fungal plant diseases and interpreting laboratory findings. 

Part I outlines the infectious diseases that affect tomato—including those caused by fungi and oomycetes, bacteria, phytoplasmas, viruses, and viroids—along with postharvest diseases and disorders and diseases caused by nematodes. Part II covers arthropod pests: namely, mites, insects, and “worm” pests. Part III examines noninfectious diseases, disorders, and damage: namely, physiological diseases, nutritional disorders, herbicide damage, and genetic diseases. Part IV, which discusses diseases of undetermined etiology, has been reorganized to adopt the format used elsewhere in the book.
