The book Principles of Plant Pathology outlines how to recognize, treat, and prevent plant diseases. It provides elaborate coverage of the various abiotic, fungal, viral, bacterial, nematode and other plant diseases and their associated epidemiology in general. The book also covers the genetics of resistance and modern management in the control of plant disease. It is the most comprehensive resource and textbook for professionals, faculty and students who can consult for well-organized and essential information both at the graduate and Post-graduate levels. It covers new discoveries and developments in the field of plant pathology and also comprises hundreds of new colour photographs and illustrations. This invaluable resource introduces the various types of organisms that are responsible for causing plant disease. Modern diagnostic techniques comprising twenty-one chapters including Epidemiology and the measurement of disease severity, The biochemistry and molecular biology of plant disease, Control through cultural, biological, genetic and molecular techniques and A wealth of examples and applications including full-colour photographs. An attempt is here made to provide a concise and straightforward account of the historical development of the diverse and interwoven themes of which the subject is composed.
