Scientists and organizations have protested the development of 2,4-D and its use in crops and pesticides. The genetically modified cotton joins the current list of unregulated GE crops which includes 2,4-D resistant corn and soybeans and is one of the unlabelled GE products on the market.
Dow’s GE cotton, part of the Enlist Weed Control System, is resistant to 2,4-D choline, glufosinate, and glyphosate. Glyphosate has been classified as a human carcinogen and is a phosphanoglycine herbicide that inhibits an enzyme essential to plant growth. The application of glyphosate has been associated with increased weed resistance and the increased application of herbicides/pesticides.
Environmental organizations and scientists had petitioned the U.S. congress not to approve the new 2,4-D tolerant combination in any capacity, citing environmental and public health concerns.
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 toxic treadmill has to stop,” said Jay Feldman, executive director of Beyond Pesticides. “EPA and USDA cannot continue to ignore the history, science, and public opinion surrounding these dangerous chemicals so that a failed and unnecessary system of chemically-dependent agriculture can continue to destroy our health and environment.”
