This is the text of a Letter to the Editor that I’ve just submitted.
Heather Hanes is wrong about the research project being initiated at the University of Regina (SP, June 16, 2014 “U of R begins pesticide research study”). They don’t have a hypothesis. They have an agenda. Tanya Dahms admits that the goal is to eliminate pesticides. Her tone implies that they are simply going through the motions to gather evidence of what they already assume to be true. A real scientific inquiry would ask “How does pesticide use affect plant populations in a grass lawn?” It is possible that killing dandelions and other noxious weeds allows non-weed species to flourish. No one can know until the study is complete and even then they might have no useful answer since two test plots is a tiny trial and the researchers are obviously biased.
