DOWNLOAD EBOOKThis 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. - 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 - Instructor resources can be found at http://textbooks.elsevier.com/web/Login.aspx, and it is password protected.

DOWNLOAD EBOOKProvides a comprehensive overview of the role of cotton in the economy and cotton production around the world This book offers a complete look at the world’s largest fiber crop: cotton. It examines its effect on the global economy—its uses and products, harvesting and processing, as well as the major challenges and their solutions, recent trends, and modern technologies involved in worldwide production of cotton. Cotton Production presents recent developments achieved by major cotton producing regions around the world, including China, India, USA, Pakistan, Turkey and Europe, South America, Central Asia, and Australia. In addition to origin and history, it discusses the recent advances in management practices, as well as the agronomic challenges and the solutions in the major cotton producing areas of the world. Keeping a focus on global context, the book provides sufficient details regarding the management of cotton crops. These details are not limited to the choice of cultivar, soil management, fertilizer and water management, pest control, cotton harvesting, and processing. The first book to cover all aspects of cotton production in a global context Details the role of cotton in the economy, the uses and products of cotton, and its harvesting and processing Discusses the current state of cotton management practices and issues within and around the world’s cotton producing areas Provides insight into the ways to improve cotton productivity in order to keep pace with the growing needs of an increasing population Cotton Production is an essential book for students taking courses in agronomy and cropping systems as well as a reference for agricultural advisors, extension specialists, and professionals throughout the industry.

DOWNLOAD EBOOKGenetically engineered (GE) crops were first introduced commercially in the 1990s. After two decades of production, some groups and individuals remain critical of the technology based on their concerns about possible adverse effects on human health, the environment, and ethical considerations. At the same time, others are concerned that the technology is not reaching its potential to improve human health and the environment because of stringent regulations and reduced public funding to develop products offering more benefits to society. While the debate about these and other questions related to the genetic engineering techniques of the first 20 years goes on, emerging genetic-engineering technologies are adding new complexities to the conversation. Genetically Engineered Crops builds on previous related Academies reports published between 1987 and 2010 by undertaking a retrospective examination of the purported positive and adverse effects of GE crops and to anticipate what emerging genetic-engineering technologies hold for the future. This report indicates where there are uncertainties about the economic, agronomic, health, safety, or other impacts of GE crops and food, and makes recommendations to fill gaps in safety assessments, increase regulatory clarity, and improve innovations in and access to GE technology.
