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

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. 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 Instructor resources can be found at http://textbooks.elsevier.com/web/Login.aspx, and it is password protected.

Weed scientists are confident of increasing production through agricultural technology, including herbicides, but do not must ask if the moral obligation to feed people is sufficient justification for the benefits and harms achieved. A continuing, rigorous examination of the science’s goals that leads to appropriate change is advocated. Weed scientists have a research consensus - a paradigm - Weeds must be controlled. Herbicides are the best control technology. Agriculture's practitoners should discuss the necessity and risks of their technology. Discussion must include scientific evidence and value-laden arguments.

As long as humans have existed, they’ve worked and competed with plants to shape their surroundings. As cities developed and expanded, their diverse spaces were covered with and colored by weeds. In Weeds, Zachary J. S. Falck presents a comprehensive history of “happenstance plants” in American urban environments. Beginning in the late nineteenth century and continuing to the present, he examines the proliferation, perception, and treatment of weeds in metropolitan centers from Boston to Los Angeles. In dynamic city ecosystems, population movements and economic cycles establish and transform habitats where vegetation continuously changes. Americans came to associate weeds with infectious diseases and allergies, illegal dumping, vagrants, drug dealers, and decreased property values. Local governments and citizens’ groups attempted to eliminate unwanted plants to better their urban environments and improve the health and safety of inhabitants. Over time, a growing understanding of the natural environment made “happenstance plants” more tolerable and even desirable. In the twenty-first century, scientists have warned that the effects of global warming and the heat-trapping properties of cities are producing more robust strains of weeds. Falck shows that nature continues to flourish where humans have struggled: in the aftermath of Hurricane Katrina, in the abandoned homes of the California housing bust, and alongside crumbling infrastructure. Weeds are here to stay.

In this book the author, an investigative journalist, traces the social history of marijuana from its origins to its emergence in the 1960s as a defining force in an ongoing culture war. He describes how the illicit marijuana subculture overcame government opposition and morphed into a multibillion-dollar industry. In 1996, Californians voted to legalize marijuana for medicinal purposes. Similar laws have followed in several other states, but not without antagonistic responses from federal, state, and local law enforcement. The author draws attention to underreported scientific breakthroughs that are reshaping the therapeutic landscape: medical researchers have developed promising treatments for cancer, heart disease, Alzheimer's, diabetes, chronic pain, and many other conditions that are beyond the reach of conventional cures. This book is an examination of the medical, recreational, scientific, and economic dimensions of the world's most controversial plant.
