text: Roughly 5,500 farmers across the country had planted more than a quarter million acres of Roundup Ready alfalfa when, in 2007, Judge Charles Breyer revoked its approval over concerns about Roundup-resistant weeds and potential effects on organic farmers concerns that USDA scientists and regulators had already considered and rejected. Fortunately, Roundup Ready alfalfa had not yet been widely adopted, and Judge Breyer's decision permitted farmers to continue to grow and then harvest the alfalfa crop they had already planted. The court's injunction only prohibited the sale of new seed until the USDA could complete the EIS and then re-approve the variety.
