Yield Environment Affects Glyphosate‐Resistant Hybrid Response to Glyphosate
Crop Science, 2007The yield response of glyphosate‐resistant corn (Zea mays L.) to glyphosate across a broad range of temporal yield environments is not well understood. Field experiments were conducted at three Michigan locations over a five year period (2002–2006) comparing corn grain yield of glyphosate‐resistant hybrids as affected by a glyphosate‐based or ...

Sustainability and Stewardship of Glyphosate and Glyphosate-resistant Crops
Weed Technology, 2007The significance of glyphosate and the appearance of glyphosate-resistant weeds have raised concerns about glyphosate sustainability. Resistance-prevention strategies, however, should first consider the mechanisms for resistance. For example, target-site resistance can provide virtual immunity, ensuring that every herbicide application successfully ...

Glyphosate and glyphosate-resistant crop interactions with rhizosphere microorganisms
European Journal of Agronomy, 2009Current crop production relies heavily on transgenic, glyphosate-resistant (GR) cultivars. Widespread cultivation of transgenic crops has received considerable attention. Impacts of glyphosate on rhizosphere microorganisms and activities are reviewed based on published and new data from long-term field projects documenting effects of glyphosate applied

The rise and future of glyphosate and glyphosate‐resistant crops
Pest Management Science, 2016AbstractGlyphosate and glyphosate‐resistant crops had a revolutionary impact on weed management practices, but the epidemic of glyphosate‐resistant (GR) weeds is rapidly decreasing the value of these technologies. In areas that fully adopted glyphosate and GR crops, GR weeds evolved and glyphosate and glyphosate traits now must be combined with other ...

Glyphosate Degradation in Glyphosate-Resistant and -Susceptible Crops and Weeds
Journal of Agricultural and Food Chemistry, 2010High levels of aminomethylphosphonic acid (AMPA), the main glyphosate metabolite, have been found in glyphosate-treated, glyphosate-resistant (GR) soybean, apparently due to plant glyphosate oxidoreductase (GOX)-like activity. AMPA is mildly phytotoxic, and under some conditions the AMPA accumulating in GR soybean correlates with glyphosate-caused ...

The control of Asian rust by glyphosate in glyphosate‐resistant soybeans
Pest Management Science, 2007AbstractBACKGROUND: Glyphosate is a widely used broad‐spectrum herbicide. Recent studies in glyphosate‐resistant (GR) crops have shown that, in addition to its herbicidal activity, glyphosate exhibits activity against fungi, thereby providing disease control benefits.

Evolution of Glyphosate-Resistant Johnsongrass (Sorghum halepense) in Glyphosate-Resistant Soybean
Weed Science, 2007In Argentinean crop fields, weed control is mainly achieved by intense use of glyphosate as a nonselective and/or selective herbicide. Glyphosate use is very high as more than 95% of the 16 million ha soybean crop consists of glyphosate-resistant cultivars, always treated with this herbicide.

Economic impacts of glyphosate‐resistant crops
Pest Management Science, 2008AbstractGlyphosate‐resistant crops have been widely planted since their introduction in 1996. Growers have numerous choices for herbicide treatments and have chosen to plant glyphosate‐resistant crops on the basis of economic factors. The economic effects of the widespread planting of glyphosate‐resistant crops have included reductions in herbicide ...

Impact of glyphosate‐resistant sugar beet
Pest Management Science, 2017AbstractGlyphosate‐resistant (GR) sugar beet became commercially available to US sugar beet growers in 2008 and was rapidly adopted. Prior to the availability of GR sugar beet, growers would commonly make 3–5 herbicide applications. This often resulted in some crop injury, but was accepted to reduce the impact of weeds.

Resistance to the herbicide glyphosate
Nature, 1998The News and Views article by Gray and Raybould1 paints a rosy picture of the future of agricultural crops engineered with resistance to the herbicide glyphosate. It is true that the presence of the glyphosate resistance transgene (the EPSPS gene) in the chloroplast genome of crop plants would ...
