The Cercospora or Cercospora-like diseases of cassava have historically been considered economically unimportant, although there were no experimental results to substatiate this view. This widely held but unsubstantiated view has hindered any serious work on these diseases. Therefore, to guide any future work on these diseases it is first necessary to establish their economic importance. The symptomatological, morhological and cultural characteristics which can be used to identify the four species inciting these diseases in cassava are presented, followed by the studies to elucidate the epidemiology and importance of brown leaf spot and Cercospora leaf blight. This study was conducted in twoinportant cassava-growing regions of Colombia, South America. The results indicate that brown leaf spot and Cercospora leaf blight are typically compound interest diseases with a long lag stage and a comparatively short logarithmic stage.

THE BALL GUIDE TO DISEASES OF ANNUALS & PERENNIALS is written for producers of annual & perennial ornamentals, commercial nurseries, landscapers, pest control operators, cooperative extension agents, educators, scientists who work with ornamentals, botanic & display gardens in the United States & Europe, master gardeners & garden club members. It is the first full/color book on diseases of annuals & perennials with an emphasis on problem identification for these crops. Color photos of disease problems allow growers, retailers & gardeners of annuals & perennials to identify crop problems so they can seek additional advice on how to solve or manage the problem. Key features of the BALL GUIDE TO DISEASES OF ANNUALS & PERENNIALS include: color photos covering -foliar diseases (botrytis, xanthomonas, rust, powdery mildew, etc.); root & stem diseases (rhizoctonia, phytophthora, pythium, canker, etc.); virus & mycoplasma diseases (aster yellows, nematodes, etc.); reference tables listing plants most susceptible to foliar diseases, root & stem diseases, virus & mycoplasma diseases, annuals & perennials by scientific & common names, non-chemical controls for diseases, grouped by disease type, symptoms of nutrient deficiency.

During the last decade, research on Pseudomonas syringae pathovars and related pathogens has progressed rapidly, opening up many new avenues. The application of molecular genetics has provided new insights into determinants of pathogenicity and virulence. Progress has also been made in elucidating the chemical structures and modes of action of phytotoxins from Pseudomonas syringae; by establishing novel strategies for disease control; in biotechnological applications; by studying the resistant reaction of the plant with a combined biochemical and genetic approach; and in the development of new detection and identification methodologies as tools in epidemiological studies. With such rapid advances it becomes more and more difficult to keep abreast of the developments and concepts within disciplines, all involving research on pathovars of P. syringae. In an attempt to provide a balanced overview, recent developments in these rapidly expanding fields have been critically reviewed at the beginning of each chapter by internationally renowned experts. Our comprehensive coverage has been made possible because all the contributors to this volume presented their latest findings at the `5th International Conference on Pseudomonas syringae Pathovars and Related Pathogens' in Berlin, September 3-8, 1995. In this way, it was possible to bring together contributions from a wide range of fields including phytopathology, genetics, bacteriology, plant breeding, plant protection, and taxonomy. This book is not intended simply as a record of the proceedings of the Berlin Conference, but as an extension of recent findings and hypotheses put forward at the meeting. All papers published in this volume have been reviewed by the Editors.
