text: For America's sugar beet growers, whose crop accounts for about half of the refined sugar consumed in the United States, the outcome was far worse. In August 2010, Judge Jeffrey White revoked the USDA's approval of Roundup Ready sugar beets on similar grounds. Although Judge White permitted Roundup Ready beets then in the ground to be grown to maturity and harvested, his decision has sown monumental confusion because an estimated 95 percent of the sugar beets currently grown in the United States are of the Roundup Ready variety. With such intense demand for the genetically engineered variety, sugar beet breeders have cut back substantially on their production of conventional seeds, meaning that beet growers cannot easily switch back to conventional varieties because supplies of seed are inadequate. The commodity price of sugar shot up by 55 percent between August and November 2010, largely as a result of the court's decision.
