Six Chemicals That Changed Agriculture is a scientific look at how the chemicals used in today's food production were developed, evaluated, and came to be in wide-spread use. From fertilizers to pest management, antibiotics to DNA, chemicals have transformed the way our food is grown, protected, and processed. Agriculture is the world's most important environment interaction, the essential human activity, and an increasingly controversial activity because of its use and presumed misuse of chemistry. The major characteristics of US agriculture for at least the last six decades have been rising productivity, declining number of mid-size farms, increasing farm size, an increasing percentage of farm production on fewer, large farms, increasing dependence of chemical technology and more developmental research being done by the agricultural chemical industry rather than by independent land-grant universities. Another equally important feature of modern agriculture is wide-spread suspicion of its technology by the public. The book will recount examples of this suspicion related to specific chemicals and present the essence of the suspicion and its results. Offers an historical analysis of the discovery and development some aspects of the chemistry of modern agriculture Addresses the advantages, disadvantages, desirable and undesirable results of the use of each of the chosen chemicals and compares and contrasts the real and frequently assumed problems of their use Provides valuable insights into the history and application of these focused chemicals, enabling readers to apply the lessons to new agricultural chemical developments

This book addresses herbicides and their use as an important aspect of modern weed management, and strives to place them in an ecological framework. Many weed scientists believe agriculture is a continuing struggle with weeds - without good weed control, good and profitable agriculture is impossible. Each agricultural discipline sees itself as central to agriculture's success and continued progress, and weed science is no exception. While not denying the importance of weed management to successful agriculture, this book places it in a larger ecological context. The roles of culture, economics, and politics in weed management are also discussed, enabling scientists and students to understand the larger effects on society. NEW TO THIS EDITION: Information on New herbicides included, along with the old herbicides that are important for understanding the history New section on weed resistance to herbicides and genetic engineering New information on invasive plants Expanded chapters on Biological Control, Pesticide Legislation and Regulation, Weed Management Systems, and more

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

I write because I am concerned that I and my agricultural colleagues have avoided addressing the moral dimension of the environmental and social problems we have contributed to. I hope for an exchange of ideas about agriculture's moral dilemmas. I encourage my readers to engage in a collective conversation about the dilemmas and avoid remaining in what Merton calls "the collective arrogance and despair of his own herd." If those engaged in agriculture continue to ignore and fail to realize our common difficulties they will be addressed and resolved by societal pressure and political action, which may not yield the resolution we favor. The book's goal is not to resolve the moral dilemmas raised. It is to raise them and encourage thought and discussion. It will ask but not answer why nearly all involved in agriculture have not addressed the moral concerns voiced by the general public. The agricultural enterprise is committed to the benefits and future success of the present, very productive, chemical, capital, and energy intensive system, which is, in the minds of many, not sustainable. The internal justification invokes the moral claim that they feed the world's population. The question remains whether or not the prevailing moral justification of feeding the world is adequate given all the issues modern, developed country agriculture faces: pesticides in soil, water, and food, cruelty to animals, Biotech/GMO's, corporate agriculture, pollution by animal factory waste, exploitation of and cruelty to migrant labor.

In 1975 workers at Life Science Products, a small makeshift pesticide factory in Hopewell, Virginia, became ill after exposure to Kepone, the brand name for the pesticide chlordecone. They made the poison under contract for a much larger Hopewell company, Allied Chemical. Life Science workers had been breathing in the dust for more than a year. Ingestion of the chemical made their bodies seize and shake. News of ill workers eventually led to the discovery of widespread environmental contamination of the nearby James River and the landscape of the small, working-class city. Not only had Life Science dumped the chemical, but so had Allied when the company manufactured it in the 1960s and early 1970s. The resulting toxic impact was not only on the city of Hopewell but also on the faraway fields where Kepone was used as an insecticide. Aspects of this environmental tragedy are all too common: corporate avarice, ignorance, and regulatory failure combined with race and geography to determine toxicity and shape the response. But the Kepone story also contains some surprising medical, legal, and political moments amid the disaster. With Poison Powder, Gregory S. Wilson explores the conditions that put the Kepone factory and the workers there in the first place and the effects of the poison on the people and natural world long after 1975. Although the manufacture and use of Kepone is now banned by the Environmental Protection Agency, organochlorines have long half-lives, and these toxic compounds and their residues still remain in the environment.
