Tomato Diseases : Identification, Biology and Control: A Colour Handbook, Second Edition

Following the successful first edition, this revised edition, contains 680 pages and 900 color photos and diagrams, covering every imaginable symptom, pest and disease affecting the tomato. This is the definitive work on the diseases and disorders of the tomato, a worldwide crop of significant economic importance. Includes over 300 high quality colour photographs Explains how to examine and identify diseases of the foliage, roots, neck, stalk and fruit Enables readers to diagnose and combat both parasitic and non-parasitic diseases of the tomato plant and fruit Following the successful first edition, this revised and greatly expanded edition Tomato Diseases: Identification, Biology and Control is the definitive work on the diseases and disorders of the tomato. The tomato is the world’s most widely produced vegetable. The number of diseases affecting the tomato is enormous: hundreds of bio-aggressors, more than 50 non-parasitic diseases, plus new and alarmingly frequent emerging diseases. Despite considerable progress to curb these diseases, they remain a constant threat to crops, often causing considerable damage. In such a context, the identification, detection, knowledge and control of these diseases—symptoms often can be very similar—are challenges that this book will help overcome. Containing more than 900 color photos, the book consists of two main parts. The first is designed as a diagnostic tool, allowing the reader to alternate between the observation of the diseased plant, environmental questions, and the prioritization of differential diagnoses. The second part comprises numerous information sheets detailing the characteristics of most tomato pathogens, geographic distribution, impact on production, types of symptoms, and life history of the plant. This section also describes the range of plant protection and disease resistance measures currently available. This unique volume is a comprehensive overview of the latest scientific knowledge on parasitic and non-parasitic tomato diseases worldwide. It will address the needs of tomato producers and keen gardeners, as well as those of researchers, teachers and their students. To identify a disease in the field, the diagnostician must have academic training and extensive knowledge of various disciplines together with experience. One must remember that in Greek, diagnosis means 'knowledge'. The extent of this knowledge is justified by the large number and diversity of the causes of diseases. Thus a good diagnostician needs to be informed of all symptoms and signs caused by disease. But expertise is not only related to the biology of pathogens (sources of contamination, modes of transmission, favorable weather) but also to understand the exact nature of the pathological context. The latter may be insufficient or inadequate, particularly in the context of a nonparasitic disease. Thanks to many observations and appropriate questions, the diagnostician will also be able to define the environmental and cultural conditions of the disease development. In fact, the diagnostician is a real detective, using a procedure constructed from his knowledge and especially his experience of diagnosis. It consists of progressive sequences of observations of the diseased plants and their different organs, of questions mainly intended to clarify the cultural context, and identifying possible hypothetical causes and prioritizing them Content: Front matter , Page 1 Copyright , Page 2 Foreword , Pages 7-9 Acknowledgements , Page 11 Introduction , Page 13 How To Use This Book , Pages 14-16 1 - The Tomato Plant and its Culture , Pages 17-34 2 - Diagnosis of Parasitic and Nonparasitic Diseases , Pages 35-230,231,233-294,295,297-342,343,345-374,375,377-411 3 - Principal Characteristics of Pathogenic Agents and Methods of Control , Pages 413,415-416,417,419-522,523,525-552,553,555-622,623,625-628,629,631-650 4 - Resistance to Diseases and Pests in Tomato , Pages 651-663 Glossary , Pages 665-667 Main works of reference , Page 669 Index , Pages 671-688 Following the successful first edition, this revised edition of Tomato Dieases, contains 680 pages and 900 color photos and diagrams, covering every imaginable symptom, pest and disease affecting the tomato.
