"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"

The Introduction to Economics for Students of Agriculture describes the universal economic principles, illustrated primarily by examples drawn from farming and the food industry. This book is composed of nine chapters, and begins with what an overview of the concepts of economics, its objective, with a particular emphasis on the mechanism of allocating scarce resources. The succeeding chapters deal with the behavior of individual through the theory of consumer choice, the concept of demand and supply, market competitions, and production economics. These topics are followed by discussions on the mobility of the factors of production and unemployment, and some problems of using the market as a resource allocator. This book will prove useful to economists, agriculturists, and students.

"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"

Global climate change is a natural process that currently appears to be strongly influenced by human activities, which increase atmospheric concentrations of greenhouse gases (GHG). Agriculture contributes about 20% of the worlds global radiation forcing from carbon dioxide, methane and nitrous oxide, and produces 50% of the methane and 70% of the nitrous oxide of the human-induced emission. Managing Agricultural Greenhouse Gases synthesizes the wealth of information generated from the GRACEnet (Greenhouse gas Reduction through Agricultural Carbon Enhancement network) effort with contributors from a variety of backgrounds, and reports findings with important international applications.

"Following the successful first edition, this revised edition, contains 680 pages and 900 color photos and diagrams, covering every imaginable symptom, pest and disease affecting the tomato. This is the definitive work on the diseases and disorders of the tomato, a worldwide crop of significant economic importance. Key Features. Includes over 300 high quality colour photographs. Explains how to examine and identify diseases of the foliage, roots, neck, stalk and fruit. Enables readers to diagnose and combat both parasitic and non-parasitic diseases of the tomato plant and fruit"
