Report: A labeling loophole means the world’s most common herbicide is even more toxic than originally believed.
By Leah Zerbe
researchers who recently tested the product’s active ingredient in combination with certain inert ones found the combo makes this weed killer much more toxic than previously disclosed. “It’s not as benign as people are led to believe,”
