Enlist Seed Launch Hinges on Not-Yet-Granted Chinese Approval

China is the sticking point when it comes to Dow AgroSciences’ Enlist Weed Control System. 

So far, China has not granted approval of the system’s soybean varieties and corn hybrids that include tolerance to glyphosate and 2,4-D choline. 

That’s put the full-scale launch for Enlist corn for 2016 in a holding pattern. Meanwhile, Enlist soybeans will be grown just for seed in 2016. 

Two types of Enlist soybeans will be offered, pending regulatory approval. Both Enlist soybeans and Enlist E3 soybeans will tolerate 2,4-D choline, glyphosate, and glufosinate. 

What’s Up With Enlist Duo

There’s better news for the system’s herbicide component. In late November, the Environmental Protection Agency (EPA) petitioned the Ninth Circuit Court of Appeals to vacate registration for Enlist Duo, the herbicide component of the Enlist system. This herbicide contains glyphosate and 2,4-D choline, a new 2,4-D formulation with lower off-target potential than existing forms. 

EPA officials are concerned that the combination of 2,4-D choline and glyphosate could result in greater toxicity than expected to non-target plants, including those classified as endangered species. EPA stated Dow had not provided this information to it before issuing the Enlist Duo registration. 

In January, though, the Court ruled against EPA motion, keeping the registration intact.

“This is a position we agreed with,” says John Chase, Dow AgroSciences Enlist commercial leader. “We continue to work with the EPA and answer their questions about the potential synergy.”

So far, Enlist Duo is approved for use in the U.S. in 15 states on corn and soybeans. They are Illinois, Indiana, Iowa, Ohio, South Dakota, Wisconsin, Arkansas, Kansas, Louisiana, Minnesota, Missouri, Mississippi, Nebraska, Oklahoma, and North Dakota.
