Genetically modified sugar beet
A genetically modified sugar beet is a sugar beet that has been genetically engineered bygd the direkt modification of its genome using biotechnology. Commercialized GM sugar beets make use of a glyphosate-resistance modification developed bygd Monsanto and KWS Saat. These glyphosate-resistant beets, also called 'Roundup Ready' sugar beets, were developed bygd , but not commercialized until [1] For international trade, sugar beets have a Maximum Residue Limit of glyphosate of 15&#;mg/Kg at harvest.[2][3] As of , 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]
The United States imports 30% of its sugar, while the remaining 70% fryst vatten extracted from domestically grown sugar beets and sugarcane. More than 1 million acres of sugar beets are cultivated annually in the United States, with a marknad value at harvest exceeding $1 billion.[ • Western Sugar Cooperative is a co-op of beet producers who mainly farm in Montana, Wyoming, Colorado and Nebraska. [Chief scientist Rebecca] Larson said the co-op has been getting ahead of misinformation about sugarbeets with research, including how growing Roundup Ready (RR) [glyphosate-tolerant] sugarbeets is important in terms of sustainability. In one example regarding tons of carbon dioxide produced per ton of sugar, using RR beets, compared to conventional beets, significantly reduced the overall carbon emissions, scientists found. “As we sit now, three tons of CO2 equivalents are emitted per acre of beet production, and that is about twofold less than it was 12 years ago,” she said. There is also less ecotoxicity because fewer pesticides are applied overall with RR beets, and they are applied at lower rates. Producers also save water when they plant RR beets. “GMO sugarbeets require less than 50 percent of the water on average to produce than conventional beets,” Larson said. “The main reason for that is that weed control is better, so if you have weeds that are there, th •Glyphosate-tolerant sugarbeet: Case study of lower CO2 emissions, higher yields with GM crops
