Monsanto's key brands include Roundup, DeKalb, Acceleron, Asgrow, Seminis and Deltapine. Its Roundup product — introduced in the 1970s — is the world's top-selling herbicide.
"It's not a surprise Bayer is dropping the Monsanto name since the brand has so many issues and there was international rejection of GMOs," said Andrew Kimbrell, executive director of the Center for Food Safety, a group that has filed several legal cases against Monsanto.
