Conteúdo: How plants defend themselves.

Plant pathology is an applied science that deals with the nature, causes and control of plant diseases in agriculture and forestry. The vital role of plant pathology in attaining food security and food safety for the world cannot be overemphasized.

Plant Disease An Advanced Treatise, Volume V: How Plants Defend Themselves describes the active, passive, physical, chemical, mechanical, and physiological defense systems of plants against the pathogens. Divided into 23 chapters, this volume discusses theories, experimental approaches, and ways to help plant defend themselves. The opening chapters of this volume deal with certain general aspects of plant defense, such as the theories of "tolerance to disease and "the time sequence of defense, including a dynamic model of defense. A chapter discusses how plant populations defend themselves in natural ecosystem and the implications of disease management on agroecosystems. Considerable chapters examine the defense by the host by analogy with defense of a medieval castle, such as perimeter, internal, and chemical defenses. Discussions on the defenses triggered by the invading pathogen; recognition and compatibility phenomena; the concept of hypersensitivity; the role of phytoalexins in defense; and the metabolic detoxification done by plants to suffer less damage from toxins are provided. This volume also discusses the theory and mechanisms of hypovirulence and hyperparasitism. The concluding chapters summarize the effects of numerous nutrients on disease and the mechanisms involved. This volume is an invaluable source for plant pathologists, mycologists, advanced researches, and graduate students.

Plant disease epidemics, caused by established and invasive pathogen species, continue to impact a world increasingly concerned with the quantity and quality of its primary food supply. The Study of Plant Disease Epidemics is a comprehensive manual that introduces readers to the essential principles and concepts of plant disease epidemiology.

Plant Pathology: An Advanced Treatise, Volume I: The Diseased Plant presents an integrated synthesis of the scope, importance, and history of plant pathology, emphasizing the concept of disease, not of diseases. The book focuses on pathological processes, defense devices, predisposition, and therapy of the diseased plant. It explores the normal pathways that are obstructed in sick plants; how the pathogen causes dysfunction; and how the host plant reacts to the pathogen. This book also considers the logistics and the strategy of disease and how to combat it. This volume is organized into 15 chapters and begins with an overview of plant pathology, its history, and its relation to other sciences, along with plant predisposition to disease, and the resistance-susceptibility problem. The next chapters examine how sickness in plants is recognized and diagnosed, the tissue breakdown in diseases, and the effects of parasites on the processes in plants. The impact of disease on water balance and respiration in plants and the histology of disease resistance in plants are also explained. This volume also covers the physiological and chemical basis of defense by higher plants against potential or invading pathogens and the hypersensitivity concept in plant pathology. The final chapter discusses the physical and chemical therapy of the diseased plant. This book will appeal to all who are interested in a theoretical treatment of plant pathology and in the broad ecological relationships among organisms, as well as to research workers and advanced students of applied biology.

Plant Pathology: An Advanced Treatise, Volume III: The Diseased Population Epidemics and Control deals with the epidemics of the diseased population of plants and their forecasting and control. The book highlights the public health implications of plant pathology, giving major consideration to inoculum production, dispersal, and control. This volume is organized into 14 chapters and begins with an overview of populations of inoculum and the consequences of cultivation, emphasizing the inoculum potential. The next chapters focus on the autonomous dispersal of plant pathogens through the soil, seeds, or plant parts; the inoculum dispersal by animals, humans, air, and water; and the factors and processes that trigger an epidemic. The book also introduces the reader to the physical, chemical, and biological aspects of the performance of fungicides on plants and in soil, and then concludes by discussing the genetics of disease resistance and problems associated with plant breeding. This book is a valuable resource for those who are interested in a theoretical treatment of plant pathology and in the broad ecological relationships among organisms, as well as for research workers and advanced students of applied biology.
