Fundamentals of Weed Science, Fifth Edition, provides the latest information on this constantly advancing area of study. Placing weed management in the largest context of weed research and science, the book presents the latest advances in the role, control and potential uses of weed plants. From the emergence and genetic foundation of weeds, to the latest means of control and environmental impact, the book uses an ecological framework to explore the role of responsible and effective weed control in agriculture. In addition, users will find discussions of related areas where research is needed for additional understanding. Explored topics include the roles of culture, economics and politics in weed management, all areas that enable scientists and students to further understand the larger effects on society.Winner of a 2019 The William Holmes McGuffey Longevity Award (College) (Texty) from the Textbook Association of AmericaCompletely revised with 35% new contentContains expanded coverage of ethnobotany, the specific identity and role of invasive weed species, organic agriculture, and herbicide resistance in GM cropsIncludes an emphasis on herbicide resistance and molecular biology, both of which have come to dominate weed science researchCovers all traditional aspects of weed science as well as current researchProvides broad coverage, including relevant related subjects like weed ecology and weed population genetics
