"It is important that scientists think about and know their history - where they came from, what they have accomplished, and how these may affect the future. Weed scientists, similar to scientists in many technological disciplines, have not sought historical reflection. The technological world asks for results and for progress. Achievement is important not, in general, the road that leads to achievement. What was new yesterday is routine today, and what is described as revolutionary today may be considered antiquated tomorrow. Weed science has been strongly influenced by technology developed by supporting industries, subsequently employed in research and, ultimately, used by farmers and crop growers. The science has focused on results and progress. Scientists have been--and the majority remain--problem solvers whose solutions have evolved as rapidly as have the new weed problems needing solutions. In a more formal sense, weed scientists have been adherents of the instrumental ideology of modern science. That is an analysis of their work, and their orientation reveals the strong emphasis on practical, useful knowledge; on know how. The opposite, and frequently complementary orientation, that has been missing from weed science is an emphasis on contemplative knowledge; that is, knowing why. This book expands on and analyzes how these orientations have affected weed sciences development. Key Features. The first analytical history of weed science to be written. Compares the development of weed science, entomology and plant pathology. Identifies the primary founders of weed science and describes their role"

Agricultural Statistics: A Handbook for Developing Countries presents the development of agricultural statistics in various countries of Africa and Asia. This book provides a guideline to those in charge of agricultural statistics in developing countries to know their priorities and to have clear objectives. Organized into 14 chapters, this book begins with an overview of the importance of regular collection of agricultural statistics to the functioning of the community as well as for its agriculture and agricultural development. This text then examines the improvement of methods of collection of existing statistics for greater dependability. Other chapters consider the yield rates and areas of crop production. This book discusses as well the direct estimation of production, which consists of large estates with their processing plants meant for processing their products only. The final chapter deals with the various organizational set-ups for the compilation of agricultural statistics. This book is a valuable resource for agriculturists and statisticians.

FROM THE PREFACE: The abundance of insects can change dramatically from generation to generation; these generational changes may occur within a growing season or over a period of years. Such extraordinary density changes or "outbreaks" may be abrupt and ostensibly random, or population peaks may occur in a more or less cyclic fashion....The goal of this book is to update and advance current thinking on the phenomenon of insect outbreaks. The contributors have reviewed relevant literature in order to generate a synthesis providing new concepts and important alternatives for future research. More importantly, they have presented new ideas or syntheses that will stimulate advances in thinking and experimentation.

"Neither pest management nor resistance management can occur with only an understanding of pest biology. For years, entomologists have understood, with their use of economic thresholds, that at least a minimal use of economics was necessary for proper integrated pest management. IRM is even more complicated and dependent on understanding and using socioeconomic factors. The new edition of Insect Resistance Management addresses these issues and much more. Many new ideas, facts and case studies have been developed since the previous edition of Insect Resistance Management published. With a new chapter focusing on Resistance Mechanisms Related to Plant-incorporated Toxins and heavily expanded revisions of several existing chapters, this new volume will be an invaluable resource for IRM researchers, practitioners, professors and advanced students. Authors in this edition include professors at major universities, leaders in the chemical and seed industry, evolutionary biologists and active IRM practitioners. This revision also contains more information about IRM outside North America, and a modeling chapter contains a large new section on uncertainty analysis, a subject recently emphasized by the U.S. Environmental Protection Agency. The final chapter contains a section on insecticidal seed treatments. No other book has the breadth of coverage of Insect Resistance Management, 2e. It not only covers molecular to economic issues, but also transgenic crops, seed treatments and other pest management tactics such as crop rotation. Major themes continuing from the first edition include the importance of using IRM in the integrated pest management paradigm, the need to study and account for pest behavior, and the influence of human behavior and decision making in IRM. Key Features. Provides insights from the history of insect resistance management (IRM) to the latest science. Includes contributions from experts on ecological aspects of IRM, molecular and population genetics, economics, and IRM social issues. Offers biochemistry and molecular genetics of insecticides presented with an emphasis on recent research. Encourages scientists and stakeholders to implement and coordinate strategies based on local social conditions"

The Role of Water in Agriculture focuses on the role of water in British agriculture. This book discusses the growing importance of hydrological science and agricultural hydrology. Organized into 14 chapters, this book begins with an overview of the problems of accurate rainfall measurement and its importance to agriculture. This text then presents a comprehensive study of the sources of error in agricultural water budgets. Other chapters consider the progress reports on two catchment studies and a report on the effect of agricultural treatments on water availability in the soil. This book discusses as well the sediment yields from forested and agricultural lands on an international basis. The final chapter deals with a summary of the discussions with conclusions and implications. This book is a valuable resource for hydrologists, geographers, meteorologists, agricultural scientists, applied biologists, plant physiologists, and pedologists. Engineers, administrators, and advisers will also find this book useful.
