Fundamentals of Weed Science provides an introduction to the basic principles of weed science for undergraduate courses. It discusses several aspects of weed biology and control, and traces the history of herbicide development. The book begins with an introduction to weeds, covering their definition, characteristics, harmful aspects, and the cost of weed control. This is followed chapters on weed classification, the uses of weeds, weed biology, weed ecology, allelopathy, the significance of plant competition, weed management and control methods, and biological weed control. Later chapters deal with herbicidesthe most important weed control tools and the ones with the greatest potential for untoward effects. Students of weed science must understand herbicides and the factors governing their use as well as the potential for misuse. These chapters discuss chemical weed control, the properties and uses of herbicides, factors affecting herbicide performance, herbicide application, herbicide formulation, ecological impact of herbicides, pesticide registration and legislation, weed management systems, and the future of weed science.

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 introduction to the principles of weed science prepares readers to analyze real-life weed control problems and to develop integrated, practical approaches to solving them. Comprehensive in coverage and unique in presentation, it blends basic information on plant systems, soil systems, control methods, and management systems, and discusses various plants and herbicides by groups to provide an integrated framework from which to extend information to many different situations. For readers interested in weed science.

WHAT DO WE KNOW ABOUT MARIJUANA AND HOW DO WE KNOW IT? Marijuana is the most frequently consumed illicit drug worldwide, with over 158.8 million users, according to the UN. Responding to public pressure, the US federal government is likely to legalize recreational marijuana within the next few years. With increasing numbers of people using cannabis both medically and recreationally there are many looming questions that only science can answer. These include: What's likely to happen, both good and bad, if the US legalizes marijuana? What are some simple, science-based rules to separate fact from fiction and to help guide policy in the highly contentious marijuana debate? Exactly what is cannabis doing in the brain that gets us high? A journey through THC neuroscience Does cannabis really have medical benefits - what's the evidence? To what extent does cannabis impair driving? Can smoking marijuana in adolescence affect IQ or risk for developing schizophrenia? Is marijuana safe to use during pregnancy? Reviews the endocannabinoid system and why our bodies are full of "weed receptors" Introduces readers to the various forms of marijuana: flower, dabs, hash, edibles, shatter, vapes, tinctures, oils and synthetics, THC, CBD and terpenes. Demonstrates how and why cannabis affects different people very differently. Discusses how MRI and PET scans can help show the effects of marijuana on the brain. Discusses long-term effects of adolescent and adult cannabis use. Examines the evidence for cannabis’s role in increasing the risk for schizophrenia-like illnesses.

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
