The fields and back roads of eastern Arkansas were a crime scene this past summer. State inspectors stopped alongside fields to pick up dying weeds. They tested the liquids in farmers' pesticide sprayers. In many cases, they found evidence that farmers were using a banned pesticide. Dozens of farmers could face thousands of dollars in fines.
The roots of the confrontation go back to a farming fiasco that took place last year. That's when the company Monsanto — now owned by Bayer — rolled out a new way to kill weeds. The company had created some special new varieties of soybeans and cotton that can tolerate a weedkiller called dicamba. Farmers could spray dicamba to kill their weeds, yet these new crops would survive. (It's a weed-killing strategy that Monsanto pioneered with "Roundup Ready" crops 20 years ago, but Roundup isn't working so well anymore. Weeds have become resistant to it.)
