The rapid change in the agro-ecosystem leaves a snag in the establishment of harmony the discard of the disturb ecosystem due to wide usage of chemical pesticides, fertilizers, and synthetic plant growth regulators. The long term effect were overlooked hence, boom of one time become bane for the ecosystem degradation. At the present context, it has become indispensable to look for sustainable crop protection management approaches for disease management and the present book is an effort to this direction. The diseases of economic importance caused by fungi, bacteria, viruses and virus like organisms of each crop are covered, describing their history, distribution, losses incurred, symptoms latest diagnostic tools, epidemiology and integrated applied management approaches including cultural, chemical, genetic resources, use of bio control agents being adopted worldwide. The layout of each chapter includes a brief introduction and pathogen-wise description of the diseases. Some chapters are vividly illustrated with photographs of typical symptoms, graphs, tables and line drawing to make the subject more interesting and easy to understand for students, scientists, planners, administrators, growers and other end users with latest pertinent references. The book contains recent information on IDM and biological control, secondary metabolites produced by biocontrol agents and their role in plant disease management, potential entomopathogenic and antagonistic fungi; fungal diseases of apple, virus diseases of cotton, sheath blight of rice, white blister (rust) of rapeseed-mustard, IDM on maize, IDM on pulses, IDM on rapeseed-mustard, sunflower, linseed, spot blotch of wheat, soil solarization in management of seedling diseases; management of bacterial diseases, anthracnose of cowpea; precision pest management, role of transgenics in plant protection, role of information technology in plant protection and physiological disorder of fruits and their management.
