Legumes provide one quarter of the world's crop protein, and the diseases which afflict them have a tremendous impact worldwide. This important collection examines the diseases of the major legume crops. Each chapter provides a review of a particular crop and its principal diseases. The chapters include discussions of etiology, biology, symptoms, epidemiology, crop loss and control, as well as extensive references. The book opens with an overview of legumes and their role in agriculture and concludes with a discussion of new disease management techniques. Written by leading experts from throughout the world, it is an indispensable resource for plant pathologists.
Cowpea: taxonomy, genetics, and breeding, physiology and agronomy, diseases and parasitic weeds, insect pests, postharvest technology and utilization. Biotechnological applications.
The first section reviews trends of bean production and constraints in Latin America and Africa. The second section covers fungal diseases. The third section, bacterial diseases. The fourth section, viral and mycoplasma diseases. The fifth section, insect pests. The last section, other bean production constraints, that is, nutritional disorders, nematodes, seed pathology, and additional problems.

The genesis of the International Food Legume Research Conference (IFLRC) can be traced back to 1983 - and so this Volume, the Proceedings of that Conference, has had a gestation period of close to five years. Professor Norman Simmonds, the perennial Book Review Editor of Experimental Agriculture, has expressed the opinion (vol. 22, p. 201, 1986) that "Many symposial volumes are just plain awful!" Elsewhere (Nature vol. 312, pp. 201-2, 1984), Anthony Watkinson - then a Commissioning Editor at Oxford University Press has described several reasons which have led him to believe that "Conference proceedings - symposia - are generally disliked . . . . To put it mildly, this type of publication has a bad name". The problems, from an author's perspective, of contributing to any many-authored publication are aired in an exchange of correspondence in Biologist (vol. 30, pp. 123 and 180, 1983; and vol. 31, pp. 3 and 69,1984). And from the editor's viewpoint, D. J. Weatherall - then Nuffield Professor of Clinical Medicine at the University of Oxford - has described (Nature vol. 317, p.
This volume focuses on issues of plant pathology and sustainability, such as short term economic plans versus long term economic visions in farming and forestry. The book also deals with the complex biological interactions governing success in minimizing pest or pathogen damage by biological or chemical strategies, benefits and costs to the producer, consequences for the environment of management options, and the challenge of defining useful farm or forest indicatorsof sustainable practices.
This work collates the information on the advances made in the control of pests of tropical food legumes, namely the cowpea, soybean, groundnut, pigeon pea and other beans. Contributors are entomologists from the IITA, the International Center of Tropical Agriculture (CIAT), the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) and researchers working in Africa, Latin America and Asia. An introduction from the USDA covers the general morphology, ecosystems, regions, distributions and uses of the crops. Chapters discuss field and storage pests, examining the taxonomy, identification, biology and bionomics, geographical distribution, status, damage symptoms and control measures for each pest covered. Also features a chapter on virus vestors and transmission of viruses and suggests strategies for future control and management of insect pests.
Most branches of science have what might be termed a 'core area' which is both related to and helps to integrate peripheral topics to form the overall subject area. Without this central link, the subject is simply a collection of disparate, albeit gener ally related topics. What genetics is to plant breeding, epidemiology is to the subject of plant pathology and, no matter what individual topic is considered, it is always possible to recognize the interaction with and relationship to epidemiological factors. Broadly speaking, until the 1950s, plant pathology was considered as the applied side of mycology and, indeed, the British Society of Plant Pathology was spawned from its mentor, the British Mycological Society, with considerable help from The Association of Applied Biology. However, with the exploding world popu lation and the growing demand for food, plant pathologists became increasingly aware of the need for a more considered, measured, precise and even holistic approach to their subject and, particularly, to plant disease management. Looking back over 40 years of teaching and research in plant pathology, it was very clear that the 'core' of the subject was epidemiology and that this 'new' study was developing a very distinct identity which was rapidly being recognized in its own right. The 'shotgun' approach to plant disease 'control' was quickly perceived to be too inexact and almost every aspect of the subject was being reviewed, refined and advanced.
Now established worldwide as the standard guide to the recognition and understanding of the causes of deterioration in temperate and tropical fruits and vegetables, these two superbly illustrated full-colour volumes deal clearly, concisely and systematically with each of the main diseases and disorders, emphasising those of importance to international trade. Dr Snowdon has designed each volume to be used in two different ways: 1. Full colour photographs and practical text provide the basis for preliminary identification by the owner or surveyor. 2. Using the microscope drawings and references, diagnosis can then be confirmed or modified by a specialist.
