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.

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

Historical development of plant pathology; Concepts of plant disease; terminology; diagnosis; classification of plant diseases; Non-parasitic agents of plant diseases; Parasitic agents of plant diseases; Variability in plant pathogens; Disease cycles; Inoculun, inoculun survival and inoculation; Pathogen's entry into plants; Colonization of the suscept; Mevhanisms of pathogenicity and host response; Mechanisms of defense; Epidemiology of plant deseases; Forecasting of plant diseases; Assessment of disease incidence and crop loss; Principles and methods of plant disease control.

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.
