I was a member of the FDA Food Advisory Committee when the agency approved production of genetically modified foods in the early 1990s.
At the time, critics repeatedly warned that widespread planting of GM crops modified to resist Monsanto’s weed-killer, Roundup, were highly likely to select for “superweeds” that could withstand treatment with Roundup….
Today, the idea that planting of GM crops is “widespread” is an understatement.
So, according to Reuters, is Roundup resistance.
“Weed resistance has spread to more than 12 million U.S. acres and primarily afflicts key agricultural areas in the U.S. Southeast and the corn and soybean growing areas of the Midwest.
“Many of the worst weeds, some of which grow more than six feet and can sharply reduce crop yields, have become resistant to the popular glyphosate-based weed-killer Roundup, as well as other common herbicides.”
This is not a trivial problem….How is the chemical industry responding to this threat? Zap it harder!
The industry is pressing the U.S. and Canadian governments to approve GM corn engineered to resist 2,4-D.
Remember 2,4-D? It was the principal ingredient in Agent Orange, the defoliant used during the Vietnam War.
Some people never learn, do they?
