USDA extends reviews on Enlist corn, dicamaba-tolerant soy

The U.S. Department of Agriculture said Friday it will extend its scrutiny of proposed biotech crops developed by Dow AgroSciences and Monsanto after receiving an onslaught of opposition to the companies’ plans.

The news frustrated Dow officials who’d hoped to have secured regulatory approval and have their new herbicide-tolerant Enlist corn brand on the market by 2014 at the latest. But 2015 is now likely the best hope for commercialization, said Dow AgroSciences spokeswoman Kenda Resler Friend.

Farmers need the new technology to better manage weeds, she said.

“They (regulators) have had a long time to look at the information,” said Friend. “This is something that farmers are going to lose from.”

USDA said it will conduct two separate environmental impact statements “to better inform decision-making” on the approvals sought by Dow and Monsanto.

Critics applauded the move. Many have warned that both the new crops planned by Dow and Monsanto, and the new herbicide use tied to the crops, will cause a range of problems for farmers and rural communities.

“USDA is taking the issue… seriously,” said Paul Towers, a spokesman for the Pesticide Action Network. “We’re hoping that a thorough review… will ultimately result in denials.”

Monsanto issued a statement calling the development “unexpected,” and saying it would co-operate with the government in the assessment. The company said farmers need its new technology to maximize crop production.

Dow AgroSciences is hit the hardest by the USDA decision as it had hoped to have approval by now, while Monsanto has been aiming for “the middle of the decade.”

Dow wants to roll out Enlist corn, and then soybeans and cotton to be used in combination with its new Enlist herbicide that combines 2,4-D and glyphosate.

The Enlist crops are genetically altered to tolerate treatments of the Enlist herbicide mixture. Dow says Enlist will help combat an explosion of crop-choking weeds around the U.S. that have become resistant to glyphosate, the broad-spectrum herbicide best known as the active ingredient in Monsanto’s Roundup.

On hold in Canada

Enlist corn and soybeans have both already picked up federal approval for release in Canada, but Dow has said it plans to wait on a Canadian release of Enlist corn pending U.S. approval, given the level of grain movement between the two countries.

Dow had already planned to hold off on releasing Enlist soybeans in Canada until 2015, to make sure approvals are first secured to export the beans to markets such as China.

Monsanto, in conjunction with BASF, wants regulatory approval for new genetically altered soybeans and cotton that resist a new dicamba-based herbicide.

Both the Enlist system and the dicamba system are seen as replacements for the combination of Roundup herbicide used on Roundup-resistant crops that now dominates U.S. agriculture.

USDA has received thousands of comments on both of the new cropping systems that laid out a variety of concerns. In addition to increasing weed resistance, many farmers fear increased use of the new herbicides that would come with the new crops would cause damage to fruits, vegetables and other crops as dicamba and 2,4-D have been known to travel on the wind far from the fields where they are sprayed.

Many also worry that the new biotech crops’ genetics will contaminate conventional and organic crops.

And Dow’s Enlist herbicide is also controversial because 2,4-D was one of the ingredients in Agent Orange, a Vietnam War-era defoliant blamed for numerous health problems suffered during and after the war.

Although the main health effects of Agent Orange are blamed on the other component of the mixture (2,4,5-T) and dioxin contamination, critics say 2,4-D has significant health risks of its own.

The Center for Food Safety had threatened to sue the government if it approved Enlist.

Center for Food Safety attorney Andrew Kimbrell said he thought the USDA had little choice but to conduct environmental impact assessments, given USDA has lost court challenges to its approvals for biotech sugarbeets and alfalfa for failing to conduct such assessments for those crops.

“I think they were between a rock and a hard place,” Kimbrell said of USDA. “They were going to be forced to do this anyway. The rush to judgment here has been halted.”

Monsanto’s dicamba-tolerant cropping system is of particular concern to farmers, said Steve Smith, chairman of the Save Our Crops farming interest coalition.

The group petitioned USDA last month to prepare just such an EIS because of the concerns about dicamba’s potential to drift and do damage to other crops.

But Cathleen Enright, executive vice-president at the Biotechnology Industry Organization (BIO), said USDA’s action sets a “bad precedent for future consideration of safe and beneficial genetically engineered plant products.”

“The U.S. regulatory system for biotech products remains unnecessarily burdensome and unpredictable, and American farmers are paying the price,” Enright said.
