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

From “Reefer Madness” to legal purchase at the corner store With long-time legal and social barriers to marijuana falling across much of the United States, the time has come for an accessible and informative look at attitudes toward the dried byproduct of Cannabis sativa. Marijuana: A Short History profiles the politics and policies concerning the five-leaf plant in the United States and around the world. Millions of Americans have used marijuana at some point in their lives, yet it remains a substance shrouded by myth, misinformation, and mystery. And nearly a century of prohibition has created an enforcement system that is racist, and the continuing effects of racially-targeted over criminalization limit economic and social opportunities in communities of color. Marijuana: A Short History tells this story, and that of states stepping up to enact change. This book offers an up-to-date, cutting-edge look at how a plant with a tumultuous history has emerged from the shadows of counterculture and illegality. Today, marijuana has become a remarkable social, economic, and even political force—with a surprising range of advocates and opponents. Over the past two decades marijuana policy has transformed dramatically in the United States, as dozens of states have openly defied the federal government. Marijuana: A Short History provides a brief yet compelling narrative that discusses the social and cultural history of marijuana but also tells us how a once-vilified plant has been transformed into a serious, even mainstream, public policy issue. Focusing on politics, the media, government, racism, criminal justice, and education, the book describes why public policy has changed, and what that change might mean for marijuana’s future place in society.

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
