Why Is Damning New Evidence About Monsanto's Most Widely Used Herbicide Being Silenced?

Huber says these facts about glyphosate are very well known scientifically but rarely cited. When asked why, he replied that it would be harder for a company to get glyphosate approved for widespread use if it were known that the product could increase the severity of diseases on normal crop plants as well as the weeds it was intended to kill. Here in the U.S., many academic journals are not even interested in publishing studies that suggest this about glyphosate; a large number of the studies Huber cites were published in the European Journal of Agronomy.
If Huber's claims are true, then it follows that there must be problems with disease in crops where glyphosate is used. Huber's second letter verifies this, saying, "we are experiencing a large number of problems in production agriculture in the U.S. that appear to be intensified and sometimes directly related to genetically engineered (GMO) crops, and/or the products they were engineered to tolerate -- especially those related to glyphosate (the active chemical in Roundup® herbicide and generic versions of this herbicide)."
He continues, saying, "We have witnessed a deterioration in the plant health of corn, soybean, wheat and other crops recently with unexplained epidemics of sudden death syndrome of soybean (SDS), Goss' wilt of corn, and take-all of small grain crops the last two years. At the same time, there has been an increasing frequency of previously unexplained animal (cattle, pig, horse, poultry) infertility and [miscarriages]. These situations are threatening the economic viability of both crop and animal producers."
Some of the crops Huber named, corn and soy, are genetically engineered to survive being sprayed with glyphosate. Others, like wheat and barley, are not. In those cases, a farmer would apply glyphosate to kill weeds about a week before planting his or her crop, but would not spray the crop itself. In the case of corn, as Huber points out, most corn varieties in the U.S. are bred using conventional breeding techniques to resist the disease Goss' wilt. However, recent preliminary research showed that when GE corn is sprayed with glyphosate, the corn becomes susceptible to Goss' wilt. Huber says in his letter that "This disease was commonly observed in many Midwestern U.S. fields planted to [Roundup Ready] corn in 2009 and 2010, while adjacent non-GMO corn had very light to no infections." In 2010, Goss' wilt was a "major contributor" to an estimated one billion bushels of corn lost in the U.S. "in spite of generally good harvest conditions," says Huber.
The subject of Huber's initial letter is a newly identified organism that appears to be the cause of infertility and miscarriages in animals. Scientists have a process to verify whether an organism is the cause of a disease: they isolate the organism, culture it, and reintroduce it to the animal to verify that it reproduces the symptoms of the disease, and then re-isolate the organism from the animal's tissue. This has already been completed for the organism in question. The organism appears in high concentrations in Roundup Ready crops. However, more research is needed to understand what this organism is and what its relationship is to glyphosate and/or Roundup Ready crops.
In order to secure the additional research needed, Huber wrote to Secretary Vilsack. Huber says he wrote his initial letter to Secretary Vilsack with the expectation that it would be forwarded to the appropriate agency within the USDA for follow-up, which it was. When the USDA contacted Huber for more information, he provided it, but he does not know how they have followed up on that information. The letter was "a private letter appealing for [the USDA's] personnel and funding," says Huber. Given recent problems with plant disease and livestock infertility and miscarriages, he says that "many producers can't wait an additional three to 10 years for someone to find the funds and neutral environment" to complete the research on this organism.
