In order to slow down or prevent the spread of resistance, the scientists are calling for big changes in the way that biotech companies, seed dealers and farmers fight this insect. The scientists urge the agency to act "with a sense of some urgency."
The rethinking that's laid out in this letter, in fact, goes beyond what the EPA is able to do under current law. For instance, the researchers want seed companies to stop routinely inserting anti-rootworm genes into their most productive hybrid seed lines. According to the letter, this practice means that farmers "often have few options" apart from rootworm-protected seeds — even in some areas where rootworms don't pose a serious problem.
