Salt, Vinegar, and Glyphosate

I’ve been asked quite a few times over the last several years about a “homemade” herbicide recipe that is floating around the web. Many of you have probably seen it posted to Facebook or Twitter or Pinterest, or on your favourite home gardening site. One of my favourite descriptions calls it a “magical, natural, weed killing potion.” The recipe is largely the same regardless of the source. There are a pretty wide variety of claims about its safety, effectiveness, and “naturalness” depending on the website. One site even says it is “an alternative to chemical weed killers.” [Spoiler: it contains chemicals.]

6 of 17 – Is Glyphosate an especially dangerous pesticide?

The pesticides in use today are significantly less toxic than those used even a few decades ago, and despite what many might think, glyphosate is actually among the safest of the bunch. If you look at the doses that have proven lethal to half of the laboratory animals tested, the so called Lethal Dose 50 (LD50), you find that some of the most common organic herbicides, such as clove oil, acetic acid, and cinnamon oil, are also more toxic than glyphosate. In fact, when it comes to the lethal dose, even table salt is more toxic than glyphosate
