A lawsuit filed in California is challenging the federal government's deregulation of alfalfa that is genetically altered to withstand the popular weed killer Roundup.

The U.S. Department of Agriculture announced Thursday that it has decided to allow unrestricted commercial planting of Monsanto’s Roundup Ready alfalfa.

The alfalfa has been genetically-engineered to tolerate the herbicide glyphosate, known commercially as Roundup.
