Book Description
The abundant weed growth in the humid and sub-humid tropics is one of the most serious constraints in producing crops, establishing pastures and maintaining water resources. This book presents historic and recent data on the biology of weeds and their control, within the general context of the husbandry of crops and the management of pastures and aquatic situations. The first seven chapters cover the nature of negative values of weeds, principles of weed ecology, weed control and establishment of farming and cropping systems in tropical regions, performance of crops in the tropical ecosystems, main weeds in the forest regions, and main weeds in the savannah regions. Chapter 8 deals with weed control methods in general and chapters 9 to 14 with weed control in various crops. Chapter 15 covers weeds and their control in pastures, and chapter 16 aquatic weed management.

Book Description
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.

Book Description
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
