Plant Diseases An Advanced Treatise, Volume III: How Plants Suffer from Disease deals with the mechanism on how individual plants suffer from disease. Organized into 19 chapters, this volume discusses plant growth, the conceptual theory of disease development in plants, and the occurrence of different kinds of impairment in diseased plant system. The opening chapters outline the array of physiological functions that are essential in the growth and development of healthy plants. This text also describes the effect of disease on the capture, transfer, and utilization of energy by plants. The subsequent chapters discuss specific types of dysfunction in plant system, including food flow, water system, mineral nutrition, and growth alteration. Other chapters deal with other plant diseases, such as crown gall, teratoma, dysfunction and shortfalls of symbiont responses, disrupted reproduction, and tissue disintegration. This volume also examines various physical factors of the environment that impose mechanical or other physical stresses on plants. It also discusses the engineering mechanics of growing plants and the effect of various pathogens and microorganisms on plant strength and plant organ structural integrity. Other chapters deal with the effect of disease on cell membrane and permeability and on intermediary plant metabolism. The concluding chapters cover the genetic aspects of diseased plants and the diseases that induce senescence and diseases that senescence induced. This volume is an invaluable source for plant pathologists and researchers, mycologists, virologists, and graduate students.

Plant Disease An Advanced Treatise, Volume II: How Disease Develops in Populations deals with the epidemiological aspect of disease in population of plants. Comprised of 18 chapters, this volume discusses the comparative anatomy, methods of research, instrumentation, computer simulation, and genetic basis of epidemics. After briefly discussing the sociology of plant pathology, the book presents the comparative anatomy of epidemics in terms of their structure, patterns of development, and dynamics. This volume describes the rational processes of epidemiological research and how they differ from the processes used to investigate disease in individual plants. A chapter examines the instrumentation for measuring the weather component, including temperature, humidity, air movement, and irradiance. Other chapters discuss the measurement of disease on whole living plants; the theory and measurement of inoculum potential; the dispersal of pathogens in both time and space; and the movement and maintenance of infectivity by pathogens that operate below ground. This volume also deals with computer simulators of plant disease and the use of predictive models to forecast epidemics for management decision making. It describes some general patterns of changes in plant-part susceptibility with time for various groups of diseases caused by fungi or viruses. A discussion on the problems of genetic uniformity and susceptibility and the breeding and deployment strategies needed to cope with these problems is included. Other chapters examine the influence of climate and weather on epidemics; the analysis of the geographical and climatic distribution of plants in various parts of the world; and the hazardous practices that have favored epidemics. Lastly, the probabilities of success for quarantines against diseases of various types are provided. This volume is an invaluable source for plant epidemiologists and pathologists, botanists, and researchers.

Plant resistance to pathogens is one of the most important strategies of disease control. Knowledge of resistance mechanisms, and of how to exploit them, has made a significant contribution to agricultural productivity. However, the continuous evolution of new variants of pathogen, ana additional control problems posed by new crops and agricultural methods, creates a need for a corresponding increase in our understanding of resistance and ability to utilize it. The study of resistance mechanisms also has attractions from a purely academic point of view. First there is the breadth of the problem, which can be approached at the genetical, molecular, cellular, whole plant or population lev~ls. Often there is the possibility of productive exchange of ideas between different disciplines. Then there is the fact that despite recent advances, many of the mechanisms involved have still to be fully elucidated. Finally, and compared with workers in other areas of biology, the student of resistance is twice blessed in having as his subject the interaction of two or more organisms, with the intriguing problems of recognition, specificity and co-evolution which this raises.

Most books on epidemiology have treated the subject from a statistical, mathematical or computer applicational point of view. However, experiments must be performed first to provide the data for models which in turn can then be proven by further experimentation. This mutual interplay of theory and empirics gives epidemiology its scientific thrust and charm. This book provides a choice of methods for varying applications and objectives, covering all important aspects for the designing of experiments. Furthermore, the reader is supplied with solutions to his experimental problems and many "tricks of the trade". The newcomer to the field will also profit by this methodology guide.

This book attempts to provide to provide concise, critical, synthetic and up-to-date coverage of different aspects of plant disease management. The first eleven chapters are devoted to principles and related aspects and the remining seven to management practices based on them. The book attempts to capture some of the images of such rapidly expanding fields as host-parasite recognition and biotechnology even at the risk of making the subject a bit conceptual. This book is intended to serve as a text for advanced undergraduate and graduate students of plant pathology and related disciplines and as a reference source for teachers, researchers, students, and technologists.

Principles of Plant Disease Management is intended to provide a substantive treatment of plant disease management for graduate and undergraduate students in which theoretical and practical elements are combined. Reference is made to specific diseases and control practices to illustrate basic principles or strategies. The section on epidemiology includes a chapter in which arthropod vectors (aphids, leafhoppers, whiteflies, Coleoptera and mites) are briefly discussed, and the section on control includes references to the use of crop varieties with resistance to such vectors, and also contains information on mechanical, cultural, biological and chemical measures that contribute to vector control. - The technology of disease management is presented according to epidemiological principles - Sections on diagnosis, epidemiology, environmental factors, disease forecasting, disease control (exclusion, physical, chemical and biological), plant resistance, cultural modifications to suppress epidemics, effects of chemicals and their major groups and uses, and examples of disease management in practice are included - A bibliography and index are appended

During the past decade epidemiology has developed beyond the simple desrip tion of ecological factors affecting disease. Population dynamics has become a major item of research, which in turn has prompted new approaches and philosophy. Though basically an empirical science, epidemiology has of necessity veered towards mathematical methods and modeling. The growing importance of epidemiology was acknowledged by the organizers of the 2nd International Congress of Plant Pathology, held in Minneapolis in September 1973. One of the symposia was devoted to a discussion of the role of mathematics and modeling in the analysis of epidemics. The speakers considered that it would be valuable to expand their contributions for publication. The following chapters give an outline of the record of achievement to date in the use of mathematical analysis and computer techniques in the study of epidemics of plant diseases; at the same time they seek to indicate the greatly enlarged possibilities, still in the early stage~ of investigation, of constructive work on this basis used in the field of epidemiology. A good beginning has been made in clarifying the very complex and sometimes confusing data by means of mathematical models and equations, and later by computer simulations. In this book practical procedures, such as experiments in coding techniques, reduction of data, computer programs, the particular scope of multiple regression analysis in the study of the progress of epidemics, disease increase and severity, disease cycles and crop losses, are variously discussed.

A comprehensive study of the causes of plant disease, the processes involved in plant-pathogen interaction, the genetics of pathogenesis, and the epidemiology of plant disease. Includes an assessment of the application of our knowledge to practical plant disease control.
