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 science's development. - 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

Revised and updated with new concepts, case studies, and laboratory exercises, Plant Pathology Concepts and Laboratory Exercises, Second Edition supplies highly detailed and accurate information in a well-organized and accessible format. New additions to the second edition include five new topic and exercise chapters on soilborne pathogens, molecular tools, biocontrol, and plant-fungal interactions, information on in vitro pathology, an appendix on plant pathology careers, and how to use and care for the microscope. An accompanying cd-rom contains figures from the text as well as supplemental full-color photos and PowerPoint slides. Unique Learning Tools Retaining the informal style of the previous edition, this volume begins each topic with a concept box to highlight important ideas. Several laboratory exercises support each topic and cater to a wide range of skill sets from basic to complex. Procedure boxes for the experimental exercises give detailed outlines and comments on the experiments, step by step instruction, anticipated results, and thought provoking questions. Case studies of specific diseases and processes are presented as a bulleted list supplying essential information at a glance. Comprehensive Coverage Divided into six primary parts, this valuable reference introduces basic concepts of plant pathology with historical perspectives, fundamental ideas of disease, and disease relationships with the environment. It details various disease-causing organisms including viruses, prokaryotic organisms, plant parasitic nematodes, fungi, plant parasitic seed plants, and other biotic and abiotic diseases. Exploring various plant-pathogen interactions including treatments of molecular attack strategies, extracellular enzymes, host defenses, and disruption of plant function, the book presents the basic ideas of epidemiology, control strategies, and disease diagnosis.
