Roundup Ready

[1] Current Roundup Ready crops include soy, corn (maize), canola,[2] sugar beets,[3] cotton, and alfalfa,[4] with wheat[5] still under development.

[citation needed] An injunction in the case of Center for Food Safety v. USDA in September, 2010 prevented farmers from planting Roundup Ready sugar beets across the United States until a remedial environmental impact report could be filed, prompting some fear of a sugar shortage.

[10] The USDA completed an environmental impact study of Roundup Ready sugar beets in 2012 and concluded that they are safe, at which time they were deregulated.

[11] In 2016, Monsanto introduced Roundup Ready Xtend soybeans, modified to tolerate both dicamba and glyphosate.

The version used in genetically modified crops was isolated from Agrobacterium strain CP4 (CP4 EPSPS) that was resistant to glyphosate.

In 1999, a review of Roundup Ready soybean crops found that, compared to the top conventional varieties, they had a 6.7% lower yield.
