At the end of each chapter, important questions have been provided for the benefit of the students. Diagrams, convincing tables and suitable graphs/illustrations are furnished at appropriate places. A complete bibliography and apt subject index are appended at the end. Besides undergraduate students, this book will also serve as a basic guide to meet the requirement of teachers/researchers in plant pathology and related fields.
