Plant Pathology deals with the diseases caused by fungi, bacteria, virus and nematodes and their management. The scientific principles involved in plant disease control, however came to light only with our understanding of the microbial nature of the diseases and the life cycle of the pathogens. The scientific approach to the problem has yielded fruitful results of great significance, mainly through the various control methods to combat various enemies of crop plants. There are review articles in this book covering topics, namely, disease scenario of bacterial diseases, biological control of crown gall, application of tissue culture in raising virus-free plants, diseases of wheat, apple, mulberry, citrus, coconut, garlic, fodder crops, opium, tea, palms, mushrooms, sorghum and their management. Information regarding management of nematode diseases of plants has been dealt with in detail. This book covers major diseases of plants and their suitable management practices. Review articles presented in the book seek to explore the changing disease scenario of plant diseases and emphasise the strategic data available for a better understanding of these diseases so that research priority areas could be identified to develop eco-friendly and socially sustainable management options. This book will be highly beneficial to students, teachers and research workers in the field of plant pathology, botany and agriculture sciences.
