Book Description
A special year like 1999 invites one to draw a balance of what has been achieved in the roughly 30 years of research and development in knowledge based systems (still abbreviated as XPS following the older term “expert systems”) and to take a look at th what the future may hold. For the 5 German conference on knowledge-based systems we therefore asked current and former speakers of the four working groups (FG’s) in the subdivision of knowledge-based systems (FA 1.5) of the German association of Informatics (GI) to present a survey of and future prospects for their respective fields: knowledge engineering, diagnosis, configuration, and case-based reasoning. An additional 14 technical papers deal with current topics in knowledge-based systems with an equal emphasis on methods and applications. They are selected from more than 50 papers accepted in the 4 parallel workshops of XPS-99: a) Knowledge Management, Organizational Memory and Reuse, b) various fields of applications, c) the traditional PuK Workshop (planning and configuration), and d) the GWCBR (German workshop on case-based reasoning). The other papers presented at these workshops are not included in this volume but are available as internal reports of Würzburg university together with the exhibition guide that emphasizing tool support for building knowledge based systems.

Book Description
Food security has been and always will be a human concern. Food security has always been fragile, threatened by a variety of factors including plant disease epidemics. Several plant disease epidemics of the past lead to questions like: What happened? How did people deal with these epidemics? What were the social and political consequences? This volume deals with such questions in six selected chapters. Chapter 1 discusses black stem rust of wheat in antiquity, and how its epidemics were perceived by the ancients. Chapter 2 reconstructs a forgotten epidemic of yellow stripe rust, 1846, on rye, a staple food in Continental Europe. Chapter 3 describes the epidemics of potato late blight in Continental Europe, 1844-46, that caused the Continental Famine and - in the longer reach - contributed to the European revolutions of 1848. Chapter 4 studies the impact of plant disease on the food situation in the neutral Netherlands during World War I. Chapter 5 looks at belligerent Germany during World War I, ravaged by plant disease. Chapter 6 treats the problem of under-rating and over-estimating the effect of plant diseases on the course of history: the effects of ergot on political events in Russia, 1722, and in France, 1779, of black stem rust on wheat on the Russian Famine, 1932/3, and of rice brown spot on the Bengal Famine, 1943. This publication is of interest to plant pathologists, historians, economists and sociologists, interested in history, and with a focus on food.

Book Description
Cassava is a major tropical tuber crop found throughout the tropics (India, Oceania, Africa and Latin America). Hitherto, there has been no single text covering all aspects of cassava biology, production and utilization. This book fills that gap, representing the first comprehensive research level overview of this main staple crop. Chapters are written by leading experts in this field from all continents. The book is suitable for those working and researching in cassava, in both developed and developing countries, as well as advanced students.

Book Description
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.

Book Description
Excessive use of chemicals and pesticide in agricultural crops is being deplored by the community and scientists. It is because of the fact that, these not only result in environmental and safety hazards but also lead to development of new strains of pests and pathogens. Thus the use of 'organic products' which do not have any utilization of chemical fertilizers and pesticides are increasing day by day. The book deals with the detailed description about a number of biopesticides which are used for management of fungi, bacteria, virus and nematodes. Topics like biological control of soil borne fungi, plant viruses, applications of bacteria, Rhizobacteria, plant species etc. are discussed in detail in the book. The traditional aspects of biopesticides management along with the future prospects and biotechnological approaches and applications have been dealt in the book. As biopesticides industry is growing at a fast pace and the use of new tools and techniques by the researchers are making it more meaningful, the volume as a whole will serve as a tool for the management of diseases in an eco-friendly manner.

Book Description
Following the original initiative of the International Organisation for Biological Control some 15 years ago, research groups and agrochemical companies have been investigating the effects of pesticides on beneficial organisms, devising laboratory and field test methods and lately developing protocols for regulatory testing requirements in Europe. This work, and the application of agreed protocols for testing, is of crucial importance to the environmentally acceptable use of pesticides and to the further development of Integrated Pest Management systems, and the objective of this book is to review the origins and progress of the research - what has been accomplished, what is the current position and what still needs to be done.

Book Description
The diagnosis and identification of plant pathogens provides the basis of plant pathology and phytomedicine. The Executive Committee of the EUROPEAN FOUNDATION FOR PLANT PATHOLOGY (EFPP) had no problem to identify this actual th topic as topic for the 4th Symposium, which was held from September 8 to the 12th at the University of Bonn. It was suggested to have introductory papers and papers on actual research on recently identified topics. The development of diagnosis and pathogen identification is very important to keep plants healthy and to provide a successful and efficient disease control. On the other hand the most important task of the EUROPEAN FOUNDATION FOR PLANT PATHOLOGY is to improve the international communication, especially in the European hemisphere. Another important duty is to provide the contact between all associated societies - of specific importance seems to be the contact to societies and colleagues from eastern European countries. Times have changed and gratefully we are obliged to hold the contact to our colleagues from the east. During the last meeting we could hold this contact to a certain extent and this should be a premise for the future. th During 1998 the EUROPEAN FOUNDATION FOR PLANT PATHOLOGY will join the 7 International Congress of Plant Pathology held at Edinburgh from August 9-14, 1998. th The 5 Symposium of the EUROPEAN FOUNDATION FOR PLANT PATHOLOGY will be arranged by our Italian colleagues.
