Dow Chemical Co., the biggest U.S. chemical maker by sales, received preliminary approval to sell a new version of its 2,4-D herbicide aimed at stopping the spread of weeds no longer killed by Monsanto Co. (MON)’s Roundup.
Enlist Duo can be sprayed on corn and soybeans that Midland, Michigan-based Dow has engineered to tolerate the weedkiller, the U.S. Environmental Protection Agency said today in a proposed decision. Public comments will be accepted for 30 days, the EPA said. Enlist Duo contains glyphosate and 2,4-D reformulated to reduce the risk of drifting onto nearby fields.
Dow is counting on Enlist herbicide and related crops to generate $1 billion in earnings as farmers look for ways to control weeds that increasingly survive glyphosate, the active ingredient in Roundup. The EPA said it would require monitoring and a remediation program to ensure weeds don’t also become resistant to 2,4-D.
“If finalized, this action will provide an additional tool to reduce the spread of glyphosate resistant weeds,” the EPA said in an Internet fact sheet on its decision.
