Available in PDF, EPUB and Kindle. Book excerpt: Despite the fact that fighting weeds was of paramount importance to the agricultural development of Canada, there has scarcely been any research on understanding the origins and history of these lowly plants. The War on Weeds in the Prairie West is the first full-blown environmental history of weeds in western Canada.

Available in PDF, EPUB and Kindle. Book excerpt: 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
Download or read book Chemical Lands written by David D. Vail and published by University of Alabama Press. This book was released on 2018 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: An exploration of the elaborate relationship between farmers, aerial sprayers, agriculturalists, crop pests, chemicals, and the environment. The controversies in the 1960s and 1970s that swirled around indiscriminate use of agricultural chemicals—their long-term ecological harm versus food production benefits—were sparked and clarified by biologist Rachel Carson’s Silent Spring (1962). This seminal publication challenged long-held assumptions concerning the industrial might of American agriculture while sounding an alarm for the damaging persistence of pesticides, especially chlorinated hydrocarbons such as DDT, in the larger environment. In Chemical Lands: Pesticides, Aerial Spraying, and Health in North America’s Grasslands since 1945 David D. Vail shows, however, that a distinctly regional view of agricultural health evolved. His analysis reveals a particularly strong ethic in the North American grasslands where practitioners sought to understand and deploy insecticides and herbicides by designing local scientific experiments, engineering more precise aircraft sprayers, developing more narrowly specific chemicals, and planting targeted test crops. Their efforts to link the science of toxicology with environmental health reveal how the practitioners of pesticides evaluated potential hazards in the agricultural landscape while recognizing the production benefits of controlled spraying. Chemical Lands adds to a growing list of books on toxins in the American landscape. This study provides a unique Grasslands perspective of the Ag pilots, weed scientists, and farmers who struggled to navigate novel technologies for spray planes and in the development of new herbicides/insecticides while striving to manage and mitigate threats to human health and the environment.
