While there is substantial evidence that many herbicides harm humans, considerable controversy regarding the use of Roundup continues to percolate within our gardening community. I hope that this article helps stimulate an informed dialogue.
Roundup, manufactured and sold by Monsanto since 1973, is the most widely-used herbicide in the U.S, with about 100 million pounds applied yearly. Past safety research has examined the effects of glyphosate, the identified active ingredient. Roundup also contains a set of ingredients portrayed by Monsanto as biologically “inert” that have, until recently, been far less examined.
Courts have found Monsanto guilty of falsely and misleadingly advertising Roundup as safe and biodegradable. In 1996, Monsanto agreed to discontinue false and misleading advertising after being sued by the Attorney General of the State of New York (NYAG). In the agreement, the NYAG described how Monsanto’s claims (that Roundup is “biodegradable,” “won’t build up in the soil,” “stays where you put it,” “can be used where kids and pets’ll play and breaks down into natural material” are: 1) not accurate because soil particles with glyphosate bound to them have been shown to ‘wash’ through or over soils, and 2) contradict EPA labeling requirements that, among other things, caution use of extreme care and avoid drift during application and inform that minute quantities can cause severe damage or destruction to the crop, plants, or other areas for which treatment was not intended.
Recent research has shown that herbicides have harmful affects on plant and amphibian life. One study, published in 2005, examined the impact of several herbicides on biodiversity of aquatic communities. Among other findings, application of Roundup resulted in a 22% reduction of overall species richness and a 70% decline in the species richness of tadpoles.
Most strikingly, in an experimental study published earlier this year, a French team of biologists found that:
