This second edition has been significantly expanded and is organized into several major sections, including a new introduction with brief histories of beet production, botany, and breeding. The remainder of the book is divided into 5 major parts: biotic disorders, abiotic disorders, postharvest deterioration of sugar beet, major insect and arthropod pests, and newly emerging issues. The description of each disease includes a general account of its importance and world distribution, symptoms, causal organism or agent, disease cycle and epidemiology, management, and selected references.

Book Description
In the last four decades of the twentieth century the use of sweetpotato was diversified beyond their classification as subsistence, food security, and famine-relief crop. In developing countries they serve both as human food and for feeding livestock. In Western countries they appeal to health conscious consumers because of their nutritional aspects. The sweetpotato is very high in nutritive value, and merits wider use on this account alone. The book has 2 parts. A general one giving up-to-date information on the history, botany, cultivars, genetic engineering, propagation, diseases and pests, nutritional data and marketing; and a second part presenting data on sweetpotato growing practices in different areas of the world. The information should be useful to researchers, practitioners and crop administrators in different countries.

With the help of 122 color photographs and thorough descriptions of pathogens, this valuable reference enables readers to easily identify diseases on the basis of symptoms and formulate field and laboratory diagnoses of diseases caused by bacteria, fungi, viruses, parasitic angiosperms, and nematodes.Readers will also learn about the geographical distribution and impact of each disease, control measures, and epidemiological aspects of diseases as well as gain knowledge on plant health problems associated with arthropods, nutritional deficiencies, herbicide injuries, and other abiotic causes. This compendium also includes sections discussing the botany of pepper, current production practices, and postharvest damage to pepper fruit.Edited and authored by 39 professionals with international expertise in pepper pathology in several unique production areas and in diverse areas of pathogen expertise, Compendium of Pepper Diseases will prove invaluable to growers, extension agents, county agents, crop production specialists, researchers, plant pathologists, horticulturists, agronomists, agribusiness professionals, educators, students and anyone interested in the diagnosis or management of diseases of pepper crops throughout the world. - Publisher.
