Book Description
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

Book Description
An authoritative and eye-opening history that examines how Monsanto came to have outsized influence over our food system. Monsanto, a St. Louis chemical firm that became the world’s largest maker of genetically engineered seeds, merged with German pharma-biotech giant Bayer in 2018—but its Roundup Ready® seeds, introduced twenty-five years ago, are still reshaping the farms that feed us. When researchers found trace amounts of the firm’s blockbuster herbicide in breakfast cereal bowls, Monsanto faced public outcry. Award-winning historian Bartow J. Elmore shows how the Roundup story is just one of the troubling threads of Monsanto’s past, many told here and woven together for the first time. A company employee sitting on potentially explosive information who weighs risking everything to tell his story. A town whose residents are urged to avoid their basements because Monsanto’s radioactive waste laces their homes’ foundations. Factory workers who peel off layers of their skin before accepting cash bonuses to continue dirty jobs. An executive wrestling with the ethics of selling a profitable product he knew was toxic. Incorporating global fieldwork, interviews with company employees, and untapped corporate and government records, Elmore traces Monsanto’s astounding evolution from a scrappy chemical startup to a global agribusiness powerhouse. Monsanto used seed money derived from toxic products—including PCBs and Agent Orange—to build an agricultural empire, promising endless bounty through its genetically engineered technology. Skyrocketing sales of Monsanto’s new Roundup Ready system stunned even those in the seed trade, who marveled at the influx of cash and lavish incentives into their sleepy sector. But as new data emerges about the Roundup system, and as Bayer faces a tide of lawsuits over Monsanto products past and present, Elmore’s urgent history shows how our food future is still very much tethered to the company’s chemical past.

Book Description
Many of the pesticides applied to food crops in this country are present in foods and may pose risks to human health. Current regulations are intended to protect the health of the general population by controlling pesticide use. This book explores whether the present regulatory approaches adequately protect infants and children, who may differ from adults in susceptibility and in dietary exposures to pesticide residues. The committee focuses on four major areas: Susceptibility: Are children more susceptible or less susceptible than adults to the effects of dietary exposure to pesticides? Exposure: What foods do infants and children eat, and which pesticides and how much of them are present in those foods? Is the current information on consumption and residues adequate to estimate exposure? Toxicity: Are toxicity tests in laboratory animals adequate to predict toxicity in human infants and children? Do the extent and type of toxicity of some chemicals vary by species and by age? Assessing risk: How is dietary exposure to pesticide residues associated with response? How can laboratory data on lifetime exposures of animals be used to derive meaningful estimates of risk to children? Does risk accumulate more rapidly during the early years of life? This book will be of interest to policymakers, administrators of research in the public and private sectors, toxicologists, pediatricians and other health professionals, and the pesticide industry.

Book Description
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.

Book Description
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.

Book Description
Pesticide use has changed considerably over the past five decades. Rapid growth characterized the first 20 years, ending in 1981. The total quantity of pesticides applied to the 21 crops analyzed grew from 196 million pounds of pesticide active ingredients in 1960 to 632 million pounds in 1981. Improvements in the types and modes of action of active ingredients applied along with small annual fluctuations resulted in a slight downward trend in pesticide use to 516 million pounds in 2008. These changes were driven by economic factors that determined crop and input prices and were influenced by pest pressures, environmental and weather conditions, crop acreages, agricultural practices (including adoption of genetically engineered crops), access to land-grant extension personnel and crop consultants, the cost-effectiveness of pesticides and other practices in protecting crop yields and quality, technological innovations in pest management systems/practices, and environmental and health regulations. Emerging pest management policy issues include the development of glyphosate-resistant weed populations associated with the large increase in glyphosate use since the late 1990s, the development of Bt-resistant western corn rootworm in some areas, and the arrival of invasive or exotic pest species, such as soybean aphid and soybean rust, which can influence pesticide use patterns and the development of Integrated Pest Management programs.

Book Description
Although chemical pesticides safeguard crops and improve farm productivity, they are increasingly feared for their potentially dangerous residues and their effects on ecosystems. The Future Role of Pesticides explores the role of chemical pesticides in the decade ahead and identifies the most promising opportunities for increasing the benefits and reducing the risks of pesticide use. The committee recommends R&D, program, and policy initiatives for federal agriculture authorities and other stakeholders in the public and private sectors. This book presents clear overviews of key factors in chemical pesticide use, including: Advances in genetic engineering not only of pest-resistant crops but also of pests themselves. Problems in pesticide useâ€"concerns about the health of agricultural workers, the ability of pests to develop resistance, issues of public perception, and more. Impending shifts in agricultureâ€"globalization of the economy, biological "invasions" of organisms, rising sensitivity toward cross-border environmental issues, and other trends. With a model and working examples, this book offers guidance on how to assess various pest control strategies available to today's agriculturist.
