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 America Completely revised with 35% new content Contains expanded coverage of ethnobotany, the specific identity and role of invasive weed species, organic agriculture, and herbicide resistance in GM crops Includes an emphasis on herbicide resistance and molecular biology, both of which have come to dominate weed science research Covers all traditional aspects of weed science as well as current research Provides broad coverage, including relevant related subjects like weed ecology and weed population genetics

This encyclopedic yet easy-to-use 2-volume set covers 262 individual entries, including a full description of 451 species and another 361 plants compared as similar species, representing 63 plant families. 13 shortcut identification tables for groups that share similar, unusual, or relatively uncommon characteristics. 2 grass identification keys - a key to all characteristics including inflorescences and reproductive parts and a key to vegetative characteristics only. 67 tables comparing important characteristics of difficult-to-distinguish weedy species. Color photos of over 700 weeds including seeds, seedlings, flowers, and mature plants. Appendix of non-native plants rarely or occasionally naturalized in California. Glossary of botanical terms. Bibliography of some of the most pertinent publications. Index to common names, scientific names, and synonyms. Each entry describes the plant category, family name, common name, and synonyms along with a summary of the important aspects of the plant’s life cycle, size, growth form, impact, method of introduction, and toxicity. You'll also find a description of the seedling, mature plant, roots and underground structures, flowers, fruits and seeds, spikelets and florets, spore-bearing structures, and post senescence characteristics for each entry. Also includes a description of the habitat where each is typically found and distribution in California, other states, and worldwide, along with maximum elevation at which the species is found. Rounding out each entry is a description of the methods of reproduction, seed dispersal, germination requirements and conditions, seed survival and longevity, early establishment characteristics and requirements, cultural practices and management options that have proven effective or ineffective in controlling infestations, and a notation of the species' inclusion on federal or state noxious weed lists.

The impact of invasive species on native vegetation is a major threat to biodiversity all over the world - a threat ranked second only to habitat destruction. Other negative effects of weed invasions include reduced ecosystem services, loss to agricultural production and impacts on human health. This work covers the discipline of risk assessment as applied to the invasion ecology of plants. Taking a global context, it synthesizes theories on plant invasions, introduces a variety of models for weed risk assessment, and addresses procedures for ranking invasive species on a range of scales to determine weeds of national significance. It shows how the application of risk assessment to weed invasion may help reduce weed impact and thereby improve living conditions for people throughout the world. This text is aimed at invasions ecologists, botanists, quarantine officers, policy-makers and community groups wanting to know more about this developing discipline.

Non-indigenous species (NIS) are common in the United States landscape. While some are beneficial, others are harmful and can cause significant economic, environmental, and health damage. This study, requested by the U.S. House Merchant Marine and Fisheries Committee, examined State and Federal policies related to these harmful NIS. The report is presented in 10 chapters. Chapter 1 identifies the issues and options related to the topic and a summary of the findings from the individual chapters that follow. Chapters 2 "The Consequences of NIS" and 3 "The Changing Numbers, Causes, and Rates of Introductions" examine basic aspects of NIS, their effects, how many there are, and how they get here. Technologies to deal with harmful NIS, including decision-making methods and techniques for preventing and managing problem species, are covered in chapters 4 "The Application of Decisionmaking Methods" and 5 "Technologies for Preventing and Managing Problems." Chapters 6, "A Primer on Federal Policy," 7 "State and Local Approaches from a National Perspective," and 8 "Two Case Studies: Non-Indigenous Species in Hawaii and Florida" assess what various institutions at the Federal, State, and local levels do, or fail to do, about NIS. Chapters 9 and 10 place NIS in a broader context by examining their relationships to genetically engineered organisms, to international law to other prominent environmental issues, and to choices regarding the future of the nation's biological resources. Appendixes include: lists of boxes, figures, and tables in the document; list of authors, workshop participants, reviewers, and survey respondents for the study; and list of references by chapter. Additional sections contain an index to common and scientific names of species, and a general index. (MDH)
