These glyphosate-resistant beets, also called 'Roundup Ready' sugar beets, were developed by 2000, but not commercialized until 2007.[1] For international trade, sugar beets have a Maximum Residue Limit of glyphosate of 15 mg/Kg at harvest.[2][3] As of 2016, GMO sugar beets are grown in the United States and Canada. In the United States, they play an important role in domestic sugar production. Studies have concluded the sugar from glyphosate-resistant sugar beets is molecularly identical to and so has the same nutritional value as sugar from conventional (non-GMO) sugar beets.[4]
