"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"

Herbivorous Insects: Host-Seeking Behavior and Mechanisms addresses mechanisms of searching behavior leading ultimately to host location of herbivorous insects. It is divided into four sections, wherein the first two sections deal with neurophysiology and the diversity of behavioral induction cues. The third section covers the searching mechanisms as affected by insects' breadth of diet. The last part examines the evolutionary analysis of the behavioral and physiological adaptations in insect/host plant relations. This book starts with an introduction to the chemical sensory system as it relates to host selection in general. This is followed by considerable discussions on host-seeking behavior and allied patterns in behavior. This text also includes the study of oviposition behavior in butterflies belonging to Papilionidae. The third section presents host selection and colonization by three insects within the saprophage-predator continuum, namely, Hylurgopinus rufipes, Scolytus multistriatus, and Pissodes strobi. The behaviors by which certain oligophagous insects locate and select food plants are also considered. The concluding part addresses the unifying theme and the diversity of responses of phytophagous insects to plants. The book provides direction toward developing a unifying theme and improving the ability to unravel the complexities of insect/plant interactions. Behaviorists, ecologists, entomologists, evolutionary biologists, and physiologists will find this book invaluable.

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.

Available water disinfection systems rely mainly on large-scale filtration and the combination of filtration (to remove solids), and subsequent application of chemical disinfectants. This has proven to produce water of acceptable quality. Important points for application in household systems are low complexity, few training requirements, and easy transportation and distribution as well as a sufficiently high acceptance by the user. Written and endorsed by the European Federation of Food Science and Technology this book compares a variety of purification systems. There is a growing evidence base on targeting water quality improvements to maximize health benefits, and it is believed that 4% of the global disease burden could be prevented by improving water supply, sanitation, and hygiene. Better tools and procedures to improve and protect drinking-water quality at the community and urban level, for example, through Water Safety Plans include the availability of simple and inexpensive approaches to treat and safely store water at the household-level.

Written by a recognized expert and based on his experience in teaching the subject to students with a variety of educational backgrounds, The Science of Grapevines: Anatomy and Physiology is the only book to comprehensively explore the physiology of the grapevine as it occurs around the world.While other books have focused on the vines of specific regions, the globalization of the wine industry and the resulting increase of lands around the world being used for grapevine cultivation have left a gap in information. This book addresses not only the specific issues and concerns of grapevines from regions around the world, but includes important emerging topics such as global climate change, water relations, temperature effect and more. Key Features * Provides global coverage of grapevines, including the regional differences, similarities, challenges and potential changes* Avoids jargon while bringing the reader into this important aspect of the wine industry * Classroom proven by a leading expert in grapevine anatomy
