Two Scientists, Two Different Approaches To Saving Bees From Poison Dust
"That pipe is close to the ground. When a tractor pulls this planter across a field, dust will get sucked into this opening, along with air. Inside the planting mechanism, "the air is rushing past that seed, it's laden with dirt, and it's acting like a sandblaster," Schaafsma says. That dirt grinds a little bit of the neonicotinoid coating from the seed, and then carries the pesticide dust with it as it exhausts from the planter, straight up into the air.
That's normally how the planter works. But Schaafsma has made some changes on this one, outfitting it with special dust traps, similar to high-quality vacuum cleaner filters. "We're probably filtering 99 percent of what comes out of the exhaust," he says.
Schaafsma thinks that this equipment, if installed on all seed planters, would eliminate most of the risk to bees from neonicotinoid-treated seeds."
