Book Description
Widespread adoption of genetically-engineered, herbicide-resistant (HR) crops have simplified crop rotation diversity and the use of single-tactic, herbicide-based weed management programs. These practices have resulted in an HR weed epidemic, where glyphosate-resistant weeds are especially problematic. Glyphosate-resistant weeds like horseweed [Conyza canadensis (L.)] and pigweeds (Amaranthus spp.) threaten grower productivity and long-term efficacy of common agronomic herbicides. Thus, integrated weed management (IWM) programs that implement both ecological- and herbicide-based tactics are needed in no-till annual grain systems to (1) manage current HR weeds, (2) reduce HR selection pressure for evolution of resistance to other herbicides, (3) preserve effective herbicide technology, (4) enhance environmental stewardship, (5) safeguard soil conservation gains, and (6) maintain farm profits and productivity. To address these goals, we established three field studies at two sites in the Mid-Atlantic and identified combinations of cover crop and herbicide tactics that achieve effective season-long annual weed management, minimize HR selection pressure, and increase sustainability by reducing herbicide inputs. The first two studies assessed the complementarity of cover crops treatments and herbicide programs in corn and soybean, where integrating a cover crop treatment combined with applying a spring, pre-plant burndown herbicide application as well as a POST-emergent application provided the most effective season-long annual weed control. The third study assessed cover crop treatments and varied management practices, such as planting and termination dates, on HR selection pressure reduction at the time of herbicide applications. While cover crops intercepted a portion of the burndown herbicide application from reaching the soil surface, weeds were effectively controlled by the cover crops before the application, thus reducing the HR selection pressure.

Book Description
Worldwide, soybean seed proteins represent a major source of amino acids for human and animal nutrition. Soybean seeds are an important and economical source of protein in the diet of many developed and developing countries. Soy is a complete protein and soyfoods are rich in vitamins and minerals.Soybean protein provides all the essential amino acids in the amounts needed for human health. Recent research suggests that soy may also lower risk of prostate, colon and breast cancers as well as osteoporosis and other bone health problems and alleviate hot flashes associated with menopause. This volume is expected to be useful for student, researchers and public who are interested in soybean.
Recent Advances in Weed Management
Author: Bhagirath S. ChauhanPublisher: Springer
ISBN: 1493910191
Category : Science
Languages : en
Pages : 414
Book Description
This volume addresses recent developments in weed science. These developments include conservation agriculture and conservation tillage, climate change, environmental concerns about the runoff of agrochemicals, resistance of weeds and crops to herbicides, and the need for a vastly improved understanding of weed ecology and herbicide use. The book provides details on harnessing knowledge of weed ecology to improve weed management in different crops and presents information on opportunities in weed management in different crops. Current management practices are also covered, along with guidance for selecting herbicides and using them effectively. Written by experts in the field and supplemented with instructive illustrations and tables, Recent Advances in Weed Management is an essential reference for agricultural specialists and researchers, government agents, extension specialists, and professionals throughout the agrochemical industry, as well as a foundation for advanced students taking courses in weed science.
Ecologically Based Weed Management

Book Description
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.
