Dow agrees to safeguards for new crops, 2,4-D weed killer combo

Reuters / A U.S. farmer group said Sept. 11 it is dropping its opposition to efforts by Dow AgroSciences to roll out a new biotech crop system in exchange for a series of commitments by Dow, including help investigating any accidental crop damage.

The deal calls for “several new safeguards” from Dow AgroSciences related to use of a reformulated herbicide and biotech crops that Dow has engineered to be used with the herbicide, and could help speed regulatory approval for the unit of Dow Chemical.

The farmer group, called Save Our Crops, represents more than 2,000 U.S. farmers and had filed legal petitions with the U.S. Department of Agriculture and the Environmental Protection Agency opposing Dow’s new crops and herbicide, together dubbed “Enlist.”

The group is one of many organizations that have protested the proposed new crop system, citing feared damage and contamination of other crops and harm to the environment and human health.

Opposition remains

Strong opposition remains. But Dow officials hope to have regulatory approval in hand quickly so they can start selling Dow’s new biotech seeds in the next few months, Dow spokesman Garry Hamlin said. U.S. farmers generally start buying seed in the fall for planting in the spring, and the selling season is just kicking off this month.

“We’ve been signalling all along that we thought differences like these could be resolved,” said Hamlin. “We think we’ve reached a favourable resolution. We want to be able to provide this to growers for 2013.”

U.S. agricultural and environmental groups have been in an uproar over Dow’s intentions to commercialize new genetically altered corn, soybeans and cotton that will withstand dousings of the new Enlist herbicide.

The herbicide combines glyphosate with a reformulated herbicide known as 2,4-D that — while long proven as an effective weed killer — is controversial for its volatile nature and toxic effects, and tangential ties as one of the elements in the “Agent Orange” defoliant used in Vietnam.

Many farmers have protested Dow’s move because they fear rising use of 2,4-D will increase the damage already done when 2,4-D drifts on the wind into fields and gardens where it kills not just weeds, but other plants and crops. Dow said it has reduced the volatility and risk of drift with the new formulation.

Amended labels

As well, Dow has agreed to amend its labelling instructions for farmers to specify for applications near sensitive crops. And Dow AgroSciences has committed to assist in investigating any damage claims on non-targeted crops, and in educating growers and applicators in proper application to reduce off-target movement, especially in areas with sensitive crops.

“With this agreement… we are no longer opposing the Enlist program,” said Steve Smith, director of agriculture at Indiana-based Red Gold, the world’s largest processor of canned tomatoes, and a leader of Save Our Crops, the coalition that had been battling Dow.

“We think Dow has done a good job understanding the necessity to put several new safeguards in place,” Smith said.

Enlist is the first in a planned series of new herbicide-tolerant crops aimed at addressing a surge in weeds that have developed resistance to Monsanto Co.’s popular Roundup herbicide.

Chemical giant BASF and Monsanto plan to unveil by the middle of this decade crops tolerant to a mix of the chemicals dicamba and glyphosate. Smith said his group remains opposed to the dicamba product.

Many critics remain opposed to 2,4-D-tolerant crops. Among other things, they are concerned that greater use of 2,4-D, will add to increased weed resistance. And several medical and public health professionals have expressed concerns that increased use of 2,4-D could be harmful to humans.

Critics have cited studies that report an association between exposure to 2,4-D and non-Hodgkin’s lymphoma, a cancer of the white blood cells that can be fatal. 2,4-D has also been linked to birth defects, neurological damage in offspring, and interference with reproductive function, according to critics.

“Opposition remains. This deal is a real disservice to those of us who are trying to get responsible regulation on this,” said Andrew Kimbrell, executive director of the Center for Food Safety, which has threatened to sue the government if it approves the new Enlist crops. “We will sue.”
