Principles of Plant Infection investigates interactions among pathogens, host plants, the environment, time and space, and their role in plant infection. It describes the principles of infection, particularly of the root, stem, or leaf, as they apply to fungi, bacteria, or viruses. It also highlights the dual nature of resistance and suggests theories of host resistance. Organized into seven chapters, this volume begins with an overview of the relation between the amount of inoculum and the amount of disease it causes. It then turns to a discussion of the disease/inoculum relations of tobacco mosaic virus; how obligate synergism restricts the transmission of pathogens; disease/inoculum relations in root disease; the independent action of spores as inoculum; variable factors other than the amount of inoculum that affect plant disease; and time as a determining factor of the degree of plant infection. The reader is also introduced to endemic disease of plants, the implications of endemicity for plant resistance to disease, the spread of disease via migration of pathogens, and the genetics of host-pathogen interactions. Plant pathologists and plant breeders will gain valuable information from this book.

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

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.

The rapid advances in concepts of different aspects of plant pathology since 1984 have compelled the present revision and expansion of the book. To avoid repetition, the chapter on plant disease management is condensed. At the same time new information on epidemiology, host-parasite relationship and genetic and molecular aspects of host-parasite interaction have been incorporated. Contents: Introduction / History of Plant Pathology / Causes of Plant Diseases / Symptoms and Indentification of Plant Diseases / Pathogenesis / Survival of Plant Pathogens / Dispersal of Plant Pathogens / The Phenomenon of Infection / Epidemiology / Effect of Infection on the Host / Role of Toxins in Plant Pathogenesis / Defence Mechanisms in Plants / Genetic Variability in Plant Pathogens / Genetics and Molecular Basis of Host-Parasite Interaction / Effect of Environments on Pathogenesis / Assessment of Disease Incidence, Severity and Loss / Disease Management Principles / Disease Management The Practices

Plant Pathology comprises art of treating a sick plant as well as science of understanding the nature of the diseased plant. Primarily aimed to cater to the needs of undergraduate students, this book provides comprehensive treatment of fundamental facts, terminology and general aspects of Plant Pathology. it provides an introduction to the subject for beginners in this field. it can also serve as a laboratory manual.
