During the two years that GE alfalfa was permitted to be grown commercially, approximately 200,000 acres of Roundup Ready alfalfa were planted — amounting to less than 1 % of the total alfalfa acres in the U.S. Cal / West Seeds, a major
alfalfa seed exporter, reported that 12 % of 200 + lots and all 6 of its research lots had tested positive for GE alfalfa in 2008 and that preliminary data indicated that 30 % of 10 seed stock lots had tested positive in 2009.
