The chapter on control of plant diseases has been recognized and expanded to include recent developments on all aspects of integrated disease management and of new chemicals, biological agents and manipulating the plant genome to develop resistant cultivar for controlling plants diseases. The information on distribution, biology, epidemiology, and control of each pathogens and disease has been updated. The book is intended to serve as a text for advanced undergraduate and post graduate students of plant pathology and related discipline and as a reference source for teacher, researchers, students, technologists, extension workers, disease scouts, agribusiness personnel, home gardeners and others interested in integrated diseases management.
