Higher yields with less pesticides was the sales pitch for genetically modified seeds. But that has not proved to be the outcome in the United States.
No advantage in yields but much higher pesticide use. And the same company that sells the pesticides also genetically modified the crops. Hmmm. Perhaps the whole argument for GMOs saving the world is false?
