No farmer in their right mind wants to poison pollinators. When I spoke with one Iowa corn farmer in January and told him about the upcoming release of a Purdue study confirming corn as a major pesticide exposure route for bees, his face dropped with worn exasperation. He looked down for a moment, sighed and said, "You know, I held out for years on buying them GE [genetically modified or engineered] seeds, but now I can't get conventional seeds anymore. They just don't carry 'em."
This leaves us with two questions: 1) What do GE seeds have to do with neonicotinoids and bees? and 2) How can an Iowa corn farmer find himself feeling unable to farm without poisoning pollinators? In other words, where did U.S. corn cultivation go wrong?
Over the last 15 years, U.S. corn cultivation has gone from a crop requiring little-to-no insecticides and negligible amounts of fungicides, to a crop where the average acre is grown from seeds treated or genetically engineered to express three different insecticides (as well as a fungicide or two) before being sprayed prophylactically with RoundUp (an herbicide) and a new class of fungicides that farmers didn't know they "needed" before the mid-2000s.
A series of marketing ploys by the pesticide industry undergird this story. It's about time to start telling it, if for no other reason than to give lie to the oft-repeated notion that there is no alternative to farming corn in a way that poisons pollinators. We were once -- not so long ago -- on a very different path.
