The destructive potential of plant diseases in modern day agriculture has increased due to the use of cultivars having narrow genetic base over large areas. Correct disease diagnosis is the prime requirement for recommending preventive or curative measures for effective disease management. The present book deals with diseases of vegetable, spices and plantation crops through thirty chapters. This book has been written in concise form and efforts have been made to in corporate information on introduction to the disease, detailed description of disease symptoms, information on pathogen disease development and management of disease with recent development towards the integrated manner. It is hoped that book will be useful to students, teachers, researchers of plant pathology, farm managers, progressive farmers and extension workers. Contents: Foreword. Preface. 1.
