This fully revised, expanded and updated edition of the successful text, Onions and Other Vegetable Alliums, relates the production and utilization of these familiar and important vegetable crops to the many aspects of plant science underpinning their production and storage technologies. Chapters cover species and crop types, plant structure, genetics and breeding, physiology of growth and development as well as pests and diseases, production agronomy, storage after harvest and the biochemistry of flavour, storage carbohydrates and colour and how this relates to nutritional and health benefits. From this wide perspective it is possible to see many examples where underlying scientific knowledge illuminates, explains and can improve agronomic practice. The reader will get an insight into how molecular methods are revolutionizing the study of taxonomy, genetics, pathology and physiology and how these methods are being applied in the breeding of improved crops.

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.

Plant breeders continue to make significant advances in developing high yield ing, adaptable, disease-free crops. These advances, however, are not realized until an efficient seed production system is in place that rapidly increases geneti cally superior crops and makes them available to the consumer in large quantities at a reasonable cost. Successful seed production requires seed to be genetically pure, free of admixtures, and able to establish rapidly a uniform stand. Seed production is a complex process. Rigorous production criteria are followed by both seed producer and seed companies to ensure that high-quality seed is produced and marketed. These criteria become even more stringent in hybrid seed production. This volume identifies the factors most critical in a successful seed production operation. The fundamental considerations common to all seed crops are established in Part I, Principles of Seed Production. From this founda tion, the practices of seed production are provided in detail in Part II, Seed Production of Specific Crops.

The book is the result of intensive work of 43 authors, all of them leading scientists in the Botrytis sciences. Each chapter describes a particular aspect of fungal biology and its impact on disease processes and host response. New technologies have arisen that when applied to long-standing problems or to test new hypotheses have been most rewarding and many of these are covered in this book. The chapters are cross linked so that readers can follow associated material.

During the past twentieth century, plant pathology has witnessed a dramatic advancement in management of plant diseases through in-depth investigations of host parasite interactions, integration of new concepts, principles and approaches. Our effort in brining out this book is to compile the achievements of modern times with regards to disease management of fruits which otherwise is widely dispersed in various scientific journals, books and government reports and to develop future strategies for the millennium. The chapters on individual crops are contributed by leading plant pathologists having authority in the respective field at international level. Each chapter includes the diseases of economic importance describing their history, distribution, symptoms, epidemiology, and integrated management approaches being adopted worldwide. Each chapter is vividly illustrated to make it more understandable to students, research and extension workers, planners, administrators and other end users citing pertinent references.

Onion (Allium cepa L.) and garlic (Allium sativum L.) are the most important Allium species cultivated worldwide and are used as vegetable and spice in our daily diet. These crops are widely cultivated for domestic consumption as well as for export purposes. They are attacked by many insect pests and diseases, which vary with region, season, and variety. This lowers the quality and yield, thereby increasing the cost of production and reduces export potential. Integrated Pest Management: strategies for onion and garlic discusses methods and tools used to minimize the incidence and severity caused by diseases and insect pests. It also focuses on the symptoms of diseases caused by various pathogens.
