Download or read book Comparison of the Eco efficiency of Conventional and Glyphosate resistant Sugarbeet Herbicide Treatments written by Carl W. Coburn and published by . This book was released on 2013 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: The introduction of glyphosate-resistant sugarbeet has greatly altered sugarbeet production practices. Compared to conventional sugarbeet herbicides, glyphosate allows for flexible and effective weed control without the need for additional tillage and hand labor. Eco-efficiency analysis is a method to compare production methods by quantifying the output produced per unit of environmental impact of the inputs used. Eco-efficiency analysis was used to compare the sustainability of conventional and glyphosate-resistant sugarbeet production. Risk quotients were calculated based on herbicide exposure and toxicity to various environmental compartments to provide an estimate of environmental impact. Yield was divided by treatment risk quotient to determine treatment eco-efficiency. Risk from the use of all herbicides was below EPA established limits. Eco-efficiency for glyphosate treatments was equal to, or greater than, all conventional treatments for all indicators with the exception of micro rate treatments for the mammalian indicator. Overall, the transfer from conventional sugarbeet herbicides to glyphosate in glyphosate-resistant sugarbeet results in a net benefit for herbicide environmental impact and sugar yield.
Download or read book Genetically Engineered Crops written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2017-01-28 with total page 607 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetically 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.

Download or read book Weed and Crop Resistance to Herbicides written by Rafael de Prado and published by Springer Science & Business Media. This book was released on 1997-05-31 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent decades, repeated use of herbicides in the same field has imposed selection for resistance in species that were formerly susceptible. On the other hand, considerable research in the private and public sectors has been directed towards introducing herbicide tolerance into susceptible crop species. The evolution of herbicide resistance, understanding its mechanisms, characterisation of resistant weed biotypes, development of herbicide-tolerant crops and management of resistant weeds are described throughout the 36 chapters of this book. It has been written by leading researchers based on the contributions made at the International Symposium on Weed and Crop Resistance to Herbicides held at Córdoba, Spain. This book will be a good reference source for research scientists and advanced students.
