EPA Extends Comment Period on Proposed Decision to Register Dicamba for Use on Genetically-Engineered Crops

For Release:  April 28, 2016

In response to requests, the EPA is extending for an additional 30 days the public comment period on the proposed regulatory decision to register dicamba to control weeds in cotton and soybean genetically engineered (GE) to tolerate dicamba. Public comments on the Agency’s proposed regulatory decision must be submitted no later than May 31, 2016. Comments may be submitted to the EPA docket EPA-HQ-OPP-2016-0187 at

These GE cotton and soybean plants are the first developed to be resistant to dicamba and are intended to allow farmers to use dicamba to control weeds that have developed resistance to glyphosate and other herbicides.

After the comment period closes, EPA will review all of the comments and reach a final decision, which the Agency expects to issue in 2016.

Questions and Answers about this proposal are available.
