The Environmental Protection Agency has approved the use of a 2,4-D weed killer called Enlist Duo to be used with the genetically modified product engineered to be resistant.
Enlist includes a combination of both the new version of 2,4-D and glyphosate and is designed to combat the escalating resistance to glyphosate which has produced super weeds.
The product was approved despite the concern expressed by scientists, medical professionals, farmers, consumer advocacy groups and the U.S. congress who petitioned the EPA to withdraw the product from the market.
Medical experts had previously advised Congress that the herbicide and the corresponding herbicide genetically resistant engineered crops would constitute a pubic health risk and cause an environmental catastrophe.
Dow AgroSciences, a subsidiary of Dow Chemical Co, has submitted application for both the 2,4-D and glyphosate herbicide and genetically engineered corn and soybean seeds genetically engineered to be resistant to the 2,4-D/glyphosate combination.
The following excerpts are briefings made to the U.S. congress by prominent scientific and medical experts.
“Exposures to herbicides in early life can lead to disease in childhood or disease later on in adult life or even old age,” said Dr. Landrigan, dean for global health at Mount Sinai School of Medicine. “Herbicide chemicals can also cross from mother to child during pregnancy and prenatal exposures that occur during the nine months of pregnancy are especially dangerous.”
“Physicians are very concerned about exposure to the combination of 2,4-D and glyphosate because of the potential lifelong and irreversible effects on the health of vulnerable populations, including children, pregnant women and farm workers,” said Dr. Thomasson, executive director of Physicians for Social Responsibility. “Policy decisions should take into account the costs that can result from failure to act on the available data on toxic herbicides.”
“2,4-D already is permitted by EPA to remain as residues on over 300 different forms of food,” said John P. Wargo, Ph.D., professor of environmental health and politics at Yale University. “Spraying millions of additional acres with these chemicals will increase their contamination of soils, surface and groundwater and foods bearing their residues. If applied by aircraft, sprays will drift to adjacent lands, potentially endangering those who reside, go to school or work nearby.”
“The biotech industry is about to repeat the same mistakes that got us into this predicament,” said Doug Gurian Sherman, Ph.D, senior scientist with Center for Food Safety. “The public must demand policies and research that help farmers adopt proven, ecologically-based farming systems with minimal pesticide use that are productive, profitable and better for society.”
“The toxic herbicide mix is being proposed because glyphosate alone is no longer working, since its overuse has led to the development of herbicide-resistant ‘superweeds’,” said Gary Hirshberg, chairman of Stonyfield Farm and Just Label It. “This ‘chemical treadmill’ benefits the GE patent holders at the expense of farmers, human health and the environment.”
In June, 35 doctors, scientists and researchers, including Dr. Chensheng (Alex) Lu of Harvard School of Public Health and Dr. Raymond Richard Neutra, a retired division chief of the California Department of Public Health, sent a letter to EPA Administrator Gina McCarthy urging her to deny Dow’s application.
“The risks of approving a new 2,4-D mixture are clear,” said Mary Ellen Kustin, senior policy analyst at the Environmental Working Group. “If approved, the use of 2,4-D would increase three-to-sevenfold by 2020, according to the USDA. The risks are too great and benefits too few to jeopardize public health and the environment.”

The EPA, as part of the approval process, is requiring a 30-foot buffer zone where the herbicide can’t be sprayed. The agency is also requiring farmers to stop spraying if wind speed is over 15 miles an hour. The approval announced Wednesday only allows the use of the weed killer in six states: Illinois, Indiana, Iowa, Ohio, South Dakota and Wisconsin.
Environmentalists and advocacy groups have suggested that the weeds will eventually become resistant to the herbicide, as they have glyphosate. The EPA responded by stating that it is requiring better surveying and reporting of weeds to try and get ahead of that problem, and the approval will expire in six years, allowing EPA to revisit the issue of resistance.
