The book provides comprehensive information on a wide range of topics from biology, physiology, genetics to the use of genomic tools in weed science. The book covers information at a more advanced level than the previously published books in weed science. It covers not only weed genetics and genomics research, but also weed management from an ecological perspective. Furthermore, the book also gives a broad coverage of novel mechanisms of weed resistance to herbicides. More importantly, it includes next generation sequencing techniques and bioinformatics of herbicide resistant genes in weeds.

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.

Weeds are the main biological constraint to crop production throughout the year. Uncontrolled weeds could cause 100% yield loss. In Australia, the overall cost of weeds to Australian grain growers was estimated at AU$ 3.3 billion annually. In terms of yield losses, weeds amounted to 2.7 million tonnes of grains at a national level. In the USA, weeds cost US$ 33 billion in lost crop production annually. In India, these costs were estimated to be much higher (US$ 11 billion). These studies from different economies suggest that weeds cause substantial yield and economic loss. Biology and Management of Problematic Weed Species details the biology of key weed species, providing vital information on seed germination and production, as well as factors affecting weed growth. These species include Chenopodium album, Chloris truncata and C. virgate, Conyza bonariensis and C. canadensis, Cyperus rotundus, and many more. This information is crucial for researchers and growers to develop integrated weed management (IWM) strategies. Written by leading experts across the globe, this book is an essential read to plant biologists and ecologists, crop scientists, and students and researchers interested in weed science. - Provides detailed information on the biology of different key weed species - Covers weed seed germination and emergence - Presents the factors affecting weed growth and seed production

Weed Biology and Climate Change will provide a synthesis of what is known regarding the probable impact of environmental change on weed biology. Chapters will look at impacts of weed biology on agriculture, invasive species that limit ecological diversity and weeds that serve as health risks. In addition it looks at current weed management strategies and how they will be affected by global climate change. The book covers an increasingly important area in plant science, crop science and ecological research, and will be essential reading for anyone exploring the biological impacts of a changing environment.

Weeds hold an enigmatic and sometimes-controversial place in agriculture, where they are generally reviled, grudgingly tolerated, and occasionally admired. In most cases, growers make considerable effort to reduce the negative economic impact of weeds because they compete with crops for resources and hinder field operations, thereby affecting crop productivity and quality, and ultimately the sustainability of agriculture. Weed control in production agriculture is commonly achieved through the integration of chemical, biological, and mechanical management methods. Chemicals (herbicides) usually inhibit the growth and establishment of weed plants by interfering with various physiological and biochemical pathways. Biological methods include crop competition, smother crops, rotation crops, and allelopathy, as well as specific insect predators and plant pathogens. Mechanical methods encompass an array of tools from short handled hoes to sophisticated video-guided robotic machines. Integrating these technologies, in order to relieve the negative impacts of weeds on crop production in a way that allows growers to optimize profits and preserve human health and the environment, is the science of weed management.

Offering much new information on the subject, this volume discusses the problems of weed control in sugarcane against the background of world-wide cultivation, with emphasis on Taiwan's intensive pattern of crop farming. After a brief botanical description of sugarcane and its cultivation in relation to weed control, the weeds themselves are studied. Chemical control of weeds, problems of crop tolerance and responses of weed species to chemicals are examined. Techniques for evaluating new herbicides, research and practices of chemical weed control in the leading industries of the world, and the application of techniques and equipment are all described in detail. The author has served the Taiwan sugar industry for more than 30 years and many of his techniques and approaches have been adopted by industries in other countries. To his own extensive experience, he has added a large amount of information published in recent years to compile this treatise which is both a contribution to the field of weed science, and a valuable practical manual for agronomists in general.

Weeds are successful plants, but on their own terms. Looking at weeds from an ecological viewpoint, emphasising the way in which one species interacts with others, the authors show that weeds are questionable mainly in that they are out-of-place.

"Weeds are rarely considered a priority despite the fact that all active farmers know that the majority of their variable costs and time are devoted to eradicating them. Even most crop losses due to pests can be traced directly back to weeds, which harbor the pests as secondary hosts. In the Molecular Biology of Weed Control, Jonathan Gressel focuses attention upon the tools of molecular biology that can be used effectively in the science of weed control. Always keeping his perspective congruent with that of the working farmer, Gressel explains how weed biologists and ecologists are beginning to use recently developed tools to control intransigent weed species in modern as well as less developed areas of the world. With his usual candor, Gressel evaluates past efforts, while also exploring future prospects for replacing chemical herbicides with genetic engineering, to improve a crop's ability to compete against its feral cousins for light, nutrients, and water. Like much of Gressel's work, this book should be mandatory reading for all agriculturists and plant scientists, so that they employ and encourage what is truly effective and efficient in meeting one of this century's most critical challenges: maximizing agricultural productivity.

Lives of Weeds explores the tangled history of weeds and their relationship to humans. Through eight interwoven stories, John Cardina offers a fresh perspective on how these tenacious plants came about, why they are both inevitable and essential, and how their ecological success is ensured by determined efforts to eradicate them. Linking botany, history, ecology, and evolutionary biology to the social dimensions of humanity's ancient struggle with feral flora, Cardina shows how weeds have shaped—and are shaped by—the way we live in the natural world. Weeds and attempts to control them drove nomads toward settled communities, encouraged social stratification, caused environmental disruptions, and have motivated the development of GMO crops. They have snared us in social inequality and economic instability, infested social norms of suburbia, caused rage in the American heartland, and played a part in perpetuating pesticide use worldwide. Lives of Weeds reveals how the technologies directed against weeds underlie ethical questions about agriculture and the environment, and leaves readers with a deeper understanding of how the weeds around us are entangled in our daily choices.
