Iowa state Sen. Bill Dotzler has traveled across Iowa’s country roads on his bicycle while training and riding for RAGBRAI. On these rides, he pays attention to farmers spraying pesticides in fields along his routes. “I’ve been out on the roads where you can see sprayers in high winds situations. You know you kind of pedal as fast as you can so you don’t get hit with it,” Dotzler, a Waterloo Democrat, said. But any efforts to add regulations to pesticide spraying in recent years at the Iowa Legislature have not gone anywhere.
