Available in PDF, EPUB and Kindle. Book excerpt: This 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 or read book Exotic Brome Grasses in Arid and Semiarid Ecosystems of the Western US written by Matthew J. Germino and published by Springer. This book was released on 2016-01-22 with total page 475 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasions by exotic grasses, particularly annuals, rank among the most extensive and intensive ways that humans are contributing to the transformation of the earth’s surface. The problem is particularly notable with a suite of exotic grasses in the Bromus genus in the arid and semiarid regions that dominate the western United States, which extend from the dry basins near the Sierra and Cascade Ranges across the Intermountain Region and Rockies to about 105° longitude. This genus includes approximately 150 species that have a wide range of invasive and non-invasive tendencies in their home ranges and in North America. Bromus species that became invasive upon introduction to North America in the late 1800’s, such as Bromus tectorum and B. rubens, have since became the dominant cover on millions of hectares. Here, millenia of ecosystem development led to landscapes that would otherwise be dominated by perennial shrubs, herbs, and biotic soil crusts that were able to persist in spite of variable and scarce precipitation. This native ecosystem resilience is increasingly coveted by land owners and managers as more hectares lose their resistance to Bromus grasses and similar exotics and as climate, land use, and disturbance-regime changes are also superimposed. Managers are increasingly challenged to glean basic services from these ecosystems as they become invaded. Exotic annual grasses reduce wildlife and livestock carrying capacity and increase the frequency and extent of wildfi res and associated soil erosion. This book uses a unique ecoregional and multidisciplinary approach to evaluate the invasiveness, impacts, and management of the large Bromus genus. Students, researchers, and practitioners interested in Bromus specifically and invasive exotics in general will benefit from the depth of knowledge summarized in the book.

Book excerpt: This book represents a current look at what we know about organic farming practices and systems, primarily from the U.S. and Canadian perspectives. the discussion begins with history and certification, ecological knowledge as the foundation for sustaining food systems, and biodiversity. The next chapters address crop-animal systems; forages, grain, oil seed, and specialty crops; organic cropping and soil nutrient needs; and vegetation and pest management. Readers will next learn about marketing organics, organic foods and food security, and education and research. The book concludes with a survey of the future of organic farming and a perspective on the agricultural industry and the future of the rural sector.--COVER.
Download or read book A Novel Method for Removing Downy Brome from Reclamation Seed written by William Rose and published by . This book was released on 2015 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Disturbance increases infestation potential for weeds such as downy brome (Bromus tectorum ). Downy brome often contaminates seed used in reclamation efforts. Because downy brome germinates more rapidly and at colder temperatures than many native grasses, it may be possible to remove downy brome from desirable seed lots by exploiting germination differences. We initiated a sequence of experiments where native grass and downy brome seeds underwent a wet germination treatment followed by a drying period. During the first experiment, we evaluated three different germination temperatures (3, 6, and 12°C) for 20-days. Downy brome germinated earlier and more rapidly than native species at all temperatures. No downy brome survived the 6°C and 12°C treatments. Survival was lower for all treated seeds compared to nontreated seeds except blue grama at 3°C. We held temperature constant (6°C) in the second experiment and compared four germination treatment durations (8, 10, 12, and 14 days). Blue grama germinability was unaffected by treatment duration in the second experiment, and thickspike wheatgrass was only reduced by the 14-day treatment. Downy brome mortality was limited in the second experiment and ranged from 4.5 to 51% depending on treatment duration. In the third experiment, we compared six drying treatments after a constant germination temperature (6°C) and duration (12 days). Blue grama and thickspike wheatgrass had the highest survival compared to downy brome. Drying seeds in commercial dryers at 30°C and 60°C severely reduced downy brome survival while maintaining high blue grama survival. Results were similar for thickspike wheatgrass in the 30°C dryer.

Download or read book Ecologically Based Weed Management written by Nicholas E. Korres and published by John Wiley & Sons. This book was released on 2023-12-06 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecologically Based Weed Management Protect crop yields and strengthen ecosystems with this essential guide Research into weed management is an increasingly critical component of both environmental stewardship and food production. The potential cost of weed propagation can be measured in crop yield reductions, under-nourished populations, stymied economies, and more. The propagation of herbicide-resistant weed populations means that purely chemical weed management is no longer viable; food production can now be secured only with an ecological approach to weed control. Ecologically Based Weed Management details such approaches and their potential to manage weeds across a range of agricultural and environmental contexts. It emphasizes the deployment of ecological principles to prevent weed infestations, reduce crop losses, and strengthen ecosystems. In a time when growing population and changing climates are placing enormous pressure on global food production, this approach to weed management has never been more vital. Ecologically Based Weed Management readers will also find: A global team of expert contributors to a multidisciplinary approach Detailed discussion of topics like herbicide limitation, integrated weed management, and more Insights pertinent to agriculture, academia, government, industry, and more Ecologically Based Weed Management is ideal for researchers in agriculture chemistry, weed science, agronomy, ecology, and related fields, as well as for regulators and advanced students.
