These new data remind us that–notwithstanding the marketing tactics of Monsanto, DuPont and Dow–our farmers and agroecosystems remain tethered to the pesticide treadmill in ways that we all pay for in one way or another.

At least two-dozen types of weeds are now resistant to glyphosate, the main ingredient in Monsanto’s Roundup. Farmers throughout the southeast and, increasingly, the Midwest, are abandoning entire fields to these ‘superweeds.’ In California, the most agriculturally productive and diverse state in the nation, weeds have developed resistance to both glyphosate and paraquat, infesting up to an estimated million acres, with the area and type of resistant weeds continuing to rise. As weeds become increasingly resistant to RoundUp, farmers use greater quantities of the product and eventually resort to older, even more dangerous pesticides. And as the Benbrook study notes, farmers are on the hook for these less effective, increasingly hazardous and expensive products.

The next cycle of the treadmill is especially frightening. 2,4-D-resistant corn is the first in a new flood of industry products currently under consideration by USDA. If the agency approves it and other 2,4-D crops, use of this hazardous pesticide in corn is expect to surge 25-fold over the next seven years, putting farms, farmers and rural communities in harm’s way. The chemical has been linked to birth defects, neurological damage and cancer, and children are especially susceptible to its effects. For these reasons, 70 medical doctors and health professionals joined Pesticide Action Network this summer in urging EPA to reject Dow AgroScience’s application for new uses of 2,4-D.

What now?

Monsanto, Dow and other major pesticide companies stand to benefit the most from the continued use of glyphosate and surge in 2,4-D and other chemical sales that will accompany the next round of herbicide-based GE crops. So it should come as no surprise that the largest opponents of California’s ‘Right to Know’ ballot initiative to label GE foods are the pesticide companies, together spending nearly $20 million to blanket the airwaves with false and misleading ads about the initiative. I am heartened, however, by recent polls showing Californians resolute in their demand that GE food be labeled.

Of even greater importance, perhaps, is the fact that people are asking serious questions about this technology, and its place in our food and farming systems. Finally we are having a genuine public conversation about genetic engineering, pesticides, our health, our rights and who should control what we eat and how we grow our food: corporations or communities. True, we should have had this conversation sixteen years ago, before the first GE seeds were ushered to market by our public agencies, without adequate safety or efficacy testing. But here and now is still a very good place to start.

Pesticide Action Network North America (PAN North America, or PANNA) works to replace the use of hazardous pesticides with ecologically sound and socially just alternatives. As one of five PAN Regional Centers worldwide, we link local and international consumer, labor, health, environment and agriculture groups into an international citizens’ action network. This network challenges the global proliferation of pesticides, defends basic rights to health and environmental quality, and works to ensure the transition to a just and viable society.
