After about 20 years of RoundUp use and 15 years of widespread planting of Monsanto's RoundUp-Ready GE crops, the efficacy of this herbicide is declining. Farmers are facing "superweeds" that can no longer be tamed by glyphosate, RoundUp's active ingredient. So now what?
Unfortunately, a new generation of crops engineered to resist mixtures of herbicide are waiting in the wings. As you've heard from my colleague Dr. Marcia Ishii-Eiteman, these new GE crops are completely the wrong response to this self-inflicted crisis. Meanwhile, researchers are raising new questions about the health and environmental effects of glyphosate itself.
