GMO Corn’s Looming Disaster
Responding to a study released last week highlighting the increased resistance of weeds to glyphosate, and the potential introduction of new corn varieties genetically engineered (GE) to be used with more highly toxic weedkillers, farmers are calling on the U.S. Department of Agriculture (USDA) to take action to protect rural economies.
If USDA deregulates 2,4 D resistant corn, farmers will once again shoulder the cost of the failed promise of GE crops.
“Widespread planting of 2,4-D corn will inevitably lead to a surge in the herbicide’s use,” said George Naylor, an Iowa corn and soybean farmer. “This will not only have adverse effects on public health from air and water pollution, but will also pose another economic risk to Midwest farmers whose non-2,4-D resistant crops will take the brunt of more herbicide drift."
The study in last week’s edition of Bioscience projects greatly increased herbicide use and collateral damage to nearby, non-resistant crops and wild habitat. 2,4-D is well understood to drift, both directly after it is applied and through volatilization, drift that takes place long after an application. As a result, farmers growing their products within miles of cornfields where 2,4-D is applied could face crop losses and serious financial hardship. In addition, organic farmers could lose their certification for years if their fields are contaminated.
Authors of the article, relying in part on industry analysis, note that use of 2,4-D and dicamba herbicides, first used during World War II, are expected to increase ten fold over the next decade. Dow AgroSciences is the driving force behind 2,4-D-resistant seeds, while Monsanto, the dominant manufacturer of glyphosate-resistant seeds, is collaborating with the European industry giant BASF (soon moving to the U.S.) in engineering dicamba-resistant seeds. And other pesticide and biotech firms have similar products in the pipeline. For years, Dow, Monsanto, and the rest of the “Big 6”, have argued that genetically engineered crops result in reduced pesticide use or can even “resist” drought, though with little to no documented success, according to independent scientists.
“Genetically engineered, herbicide-resistant seeds are the growth engines of the pesticide industry’s market strategy,” said Dr. Marcia Ishii-Eiteman, PhD, senior scientist at Pesticide Action Network. “Repackaging antiquated pesticides as new solutions for Midwest economies is a disaster waiting to happen.”
The study also ties the increase in herbicide use to the decline of sustainable weed management. The authors note that USDA has increased funding at major universities for chemically-intensive methods while at the same time decreasing funding for agroecological methods—such as cover cropping, crop rotation and limited tillage—that are successful at improving weed control and reducing weed pressures.
At the same time, weed scientists have been raising red flags around the impending problems of resistance, the reliance on the “pesticide treadmill” and the need to invest in sustainable weed control, or Integrated Weed Management.
"It is only going to get worse," said Lee Van Wychen, director of science policy at the Weed Science Society of America in a Reuter’s interview.
The Weed Society of America just announced it will focus its May 2012 meeting on finding solutions to herbicide resistance. However, concerns remain about Monsanto’s efforts to undermine science and promote the next wave of GE technology, including 2,4-D and dicamba.
"I'm convinced that this is a big problem," said Dave Mortensen, professor of weed and applied plant ecology at Penn State University. "Most of the public doesn't know because the industry is calling the shots on how this should be spun."

Get ready to toast bees, butterflies and hummingbirds. National Pollinator Week is June 17-23 and it's a perfect time to celebrate the birds, bugs and lizards that are so essential to the crops we grow, the flowers we smell, and the plants that produce the air we breathe.
The U.S Forest Service unveiled a new plan to skirt a major environmental law that requires extensive review for new logging, road building, and mining projects on its nearly 200 million acres of public land. The proposal set off alarm bells for environmental groups, according to Reuters.

In the summer of 1969 a banner hung over a set of condemned homes in what was then the predominantly black and brown Brookland neighborhood in Washington, DC. It read, "White man's roads through black men's homes."
Earlier in the year, the District attempted to condemn the houses to make space for a proposed freeway. The plans proposed a 10-lane freeway, a behemoth of a project that would divide the nation's capital end-to-end and sever iconic Black neighborhoods like Shaw and the U Street Corridor from the rest of the city.
Michigan prosecutors dropped all criminal charges against government officials involved in the Flint water crisis Thursday, citing concerns about the investigation they had inherited from the Office of Special Counsel (OSC) appointed by former Attorney General Bill Schuette, CNN reported.
