Sustainability of Glyphosate-based Weed Management: The Benchmark Study
Micheal Owen, Philip Dixon, David Shaw, Stephen Weller, Bryan Young, Robert Wilson, and David Jordan
The benefits and risks of the widespread adoption of genetically engineered glyphosate resistant (GE GR) crops on agroecosystems and for society has been a contentious topic of debate in scientific journals and the popular media. The complexity of assessing benefits and risks of GE GR crops is great, and often there is considerable variability, depending on the specific GE under assessment. Risks attributed to the adoption of GE GR crops include the alleged displacement of small-farmers, food safety apprehensiveness, GE pollen movement to wild species, volunteer GE GR crops, and other issues. One risk that is significant is the evolved resistance to glyphosate in weeds.
