roundup

Mark Twain supposedly once said, "Never let the truth get in the way of a good story," but there is a difference between a good story told in fun and a story (supposedly backed by independent scientific research) that people are led to believe because, well, science is supposed to be true. And so we come to the story of Roundup, the herbicide developed by Monsanto that swept the world because it worked and was the “safe” alternative to widely used weedkillers like Dicamba and 2,4-D,—it was said to be safer than table salt!

Roundup was developed in the 1970s as a non-selective herbicide, meaning it would kill almost any growing plant it touched. It was an effective burn-down herbicide farmers could apply prior to planting, and it assured an almost weed-free field at the beginning of the growing season. Roundup could be used in non-agricultural situations as well, to kill weeds and grass growing in sidewalk and patio cracks, around buildings, etc, but care was needed because, as noted, it was non-target and could kill whatever plant it touched.
