Transgenic glyphosate-resistant crops (GRCs) have been commercialized and grown extensively in the Western Hemisphere and, to a lesser extent, elsewhere. GRCs have generally become dominant in those countries where they have been approved for growing. Potential effects of glyphosate on soil and water are minimal, compared the effects of the herbicides that are replaced when GRCs are adopted. Perhaps the most important indirect effect is that GRCs crops promote the adoption of reduced- or no…

Abstract Glyphosate is the most used herbicide worldwide, which has contributed to concerns about its environmental impact. Compared with most other herbicides, glyphosate has a half-life in soil and
Agriculture and Environmental Impacts of Glyphosate-Tolerant Soybean Cultivation in Romania
Glyphosate-resistant soybeans (GRS) were grown commercially in Romania beginning with1999 and accounted for 68 % (or 137,000 ha) of the entire soybean area planted in 2006. Since 2007, after its
Glyphosate Effects on Plant Mineral Nutrition, Crop Rhizosphere Microbiota, and Plant Disease in Glyphosate-Resistant Crops
Most of the available data support the view that neither the GR transgenes nor glyphosate use in GR crops increases crop disease and yield data on GR crops do not support the hypotheses that there are substantive mineral nutrition or disease problems that are specific to GR crops.
Farming without Glyphosate?
Model predictions suggest that the authors can farm profitably without glyphosate by consistently utilizing key non-herbicidal weed management practices combined with robust pre-emergence soil residual herbicide treatments, however, maintaining low weed seed banks will be challenging.
Terrestrial Non-Parasitic Nematode Assemblages associated With Glyphosate-tolerant and Conventional Soybean-Based Cropping Systems
Bacterivores had the greatest diversity in soils of all three ecosystems during both seasons, while fungivores tended to be more abundant in glyphosate-tolerant soybean fields especially during the second season.
Role of transgenic plants in agriculture and biopharming.
Integrated weed management systems with herbicide-tolerant crops in the European Union: lessons learnt from home and abroad
Based on the experience gained in countries where CHT or GMHT crops are widely grown and the increased familiarity with their management, five actions are proposed to facilitate the integration of HT crops in IWM systems within the European Union.
The challenge of herbicide resistance around the world: a current summary.
This review endeavors to provide a current overview of herbicide resistance challenges in the major crop production areas of the world and discusses some research initiatives designed to address portions of the problem.


Potential environmental impacts of herbicide-resistant crops.
Transgenic bromoxynil-, glufosinate-, and glyphosate-resistant crops have been commercialized and grown extensively in the Western Hemisphere and, to a lesser extent, elsewhere and one weed species has evolved resistance in glyphosate- resistant crops.
The current status and environmental impacts of glyphosate-resistant crops: a review.
Glyphosate-resistant crops have promoted the adoption of reduced- or no-tillage agriculture in the USA and Argentina, providing a substantial environmental benefit and the development and use of failsafe introgression barriers in crops with such linked genes is needed.
Comparison of herbicide regimes and the associated potential environmental effects of glyphosate-resistant crops versus what they replace in Europe.
Favourable environmental effects of the glyphosate-containing herbicide regimes on GR crops appear feasible, provided appropriate measures for maintaining biodiversity and prevention of volunteers and gene flow are applied.
Review of potential environmental impacts of transgenic glyphosate-resistant soybean in Brazil
Transgenic glyphosate-resistant soybeans have been commercialized and grown extensively in the Western Hemisphere, including Brazil, and four weed species have evolved resistance to glyphosate in GRS in Brazil and have great potential to become problems.

On the basis of recent adoption rates by growers around the world, it appears that glyphosate-resistant crops will continue to grow in number and in hectares planted, however, global public acceptance of biotechnology-derived products willcontinue to impact the rate of adoption of this and other new innovations derived from transformation technology.
Herbicides, glyphosate resistance and acute mammalian toxicity: simulating an environmental effect of glyphosate-resistant weeds in the USA.
It has been found that GR crops have a positive environmental effect, and that alternatives to GR technology increase toxicity.
Glyphosate-resistant crops: adoption, use and future considerations.
GRCs represent one of the more rapidly adopted weed management technologies in recent history and current use patterns would indicate that GRCs will likely continue to be a popular weed management choice that may also include the use of other herbicides to complement glyphosate.

The economic effects of the widespread planting of glyphosate-resistant crops have included reductions in herbicide expenses, increases in seed costs, increased yield and changes in the relative profitability of crops that has resulted in changes in which crops are planted.
Integrating soil conservation practices and glyphosate-resistant crops: impacts on soil.
Glyphosate use may result in minor effects on soil biological/chemical properties, however, enhanced organic carbon and plant residues in surface soils under conservation practices may buffer potential effects of glyphosate.
Glyphosate: a once-in-a-century herbicide.
The use of this virtually ideal herbicide is now being threatened by the evolution of glyphosate-resistant weeds, and adoption of resistance management practices will be required to maintain the benefits of glyphosate technologies for future generations.
