Neonicotinoids"neonics" for short"[are] now the most common chemicals used to kill bugs in American agriculture. Farmers can spray them on fields, but these insecticides are also attached to seeds as an outer coating, called a seed treatment. As the seeds germinate and grow, the plant's tissues become toxic. Research shows neonics threaten pollinators, birds, aquatic organisms, and mammals, and pose risks to humans. Data from 2015 to 2016 showed about half of Americans over three years old were recently exposed to a neonic. Nearly all commodity corn farmers receive seed coated with neonics at the start of each season; many cannot identify the chemical that's in the coating and don't even know if another option exists. In corn and soy fields, new research ... suggest that widespread use of neonic-treated seeds provide minimal benefit to farmers. One study from Quebec helped convince the Canadian province to change its laws to restrict the use of neonic seed treatments. After five years and a 95 percent drop in the use of neonic-coated seeds, there have been no reported impacts on crop yields. For agronomist Louis Robert, the success of the Quebec government's decision to move away from neonics on corn and soy seeds is apparent ... in the silence. "The most reliable proof is that it's not even a matter of discussion anymore," Robert said. "Today, as we speak in 2024 in Quebec, over half of the corn and soy acreage doesn't carry any insecticide, and we're going to have a fantastic year in terms of yield. So, the demonstration is right there in front of you."
