USDA downplays own scientist’s research on ill effects of Monsanto herbicide

By Tom Laskawy

Prior to Andrés Carrasco’s September 2010 report (GM Soy: Sustainable? Responsible?) exposing that glyphosate causes birth defects and cancer, in April of this year, Reuters uncovered evidence by USDA scientist, Robert Kremer, who showed that the herbicide destroys the soil. Kremer told Grist writer Tom Laskawy that it also lowers plant productivity and increases its vulnerability to destructive soil microbes, among other deleterious effects.


What would happen if a USDA scientist discovered that one of the most commonly used pesticides on the planet with a reputation for having saved millions of tons of US soil from erosion was — rather than a soil savior — a soil killer?

That, to quote a certain paranormal expert, would be bad. And yet, it’s true.

This news came to the fore thanks to a recently published must-read article [reproduced below] from Reuters on how government regulators are “dropping the ball” on agricultural biotechnology. It begins with the story of USDA scientist Dr. Robert Kremer. Kremer has spent the last fifteen years looking at Monsanto’s blockbuster broad-spectrum herbicide glyphosate (aka RoundUp), the most commonly used pesticide in the world and the companion to Monsanto’s possibly monopolistic RoundupReady lines of genetically engineered seeds.

While exact figures are a closely guarded secret thanks to the USDA’s refusal to update its pesticide use database after 2007, estimates suggest upwards of 200 million pounds of glyphosate were dumped on fields and farms in the US in 2008 alone. That’s almost double the amount used in 2005.

Glyphosate has a reputation as the “safest” of all the agricultural herbicides and has become the primary means of weed control in industrial agriculture. While being the best of an extremely nasty bunch may be the faintest of praise, the USDA relies on this perception, which has been fueled by industry and government research indicating that the chemical dissipates quickly and shows low toxicity (as poisons go, that is) to humans.

The claim of “millions of tons of soil saved” relates to the soil that would have otherwise been lost to erosion without glyphosate’s central role in chemical no-till farming techniques. Indeed, experts such as Dr. Michael Shannon, a program director at the USDA’s Agricultural Research Service, as well as other USDA scientists, make this anti-erosion claim the core argument in favor of the widespread use of the chemical.

Even so, glyphosate has been under attack from several quarters of late. Research indicates that, while glyphosate on its own may be relatively “safe,” it is actually quite toxic in combination with the other (supposedly “inert”) ingredients in commercial preparations of the herbicide, i.e. the stuff that farmers actually spray on their fields.

And of course, there is the frightening spread of superweeds that glyphosate can no longer kill. It’s to the point that thousands of acres in the South have been abandoned to resistant strains of giant pigweed.

Enter Dr. Kremer. His work, published in the peer-reviewed Journal of European Agronomy, further tarnishes glyphosate’s golden status. He has found that glyphosate’s side-effects in the ground are far more severe than previously thought. As he described it to me, the use of glyphosate causes:

  1. I find it so discouraging that the FDA treats Monsanto-generated studies as objective research. This all stems back to the control the corporations have over our government.
    As long as we’re letting corporations become so instrumental in policy setting, we’ll always have compromised policies.

  2. Corporate Government=Bad for the People. The chain MUST be broken!!! Grow your own, eat local, buy local, and give the big Finger to the corporations!
