The Environmental Protection Agency is proposing to register dicamba to control weeds in cotton and soybean genetically engineered to tolerate the pesticide.
Due to several requests, the comment period has been extended until May 31, to allow sufficient time to review the numerous technical documents contained with the proposal.
Weeds that are becoming increasingly resistant to glyphosate-based herbicides are posing a problem for farmers. If finalized, EPA's action will provide an additional tool to reduce the spread of glyphosate resistant weeds.
To ensure that dicamba successfully manages weed resistance problems, the proposed decision outlines a Herbicide Resistance Management Plan which includes robust monitoring and reporting any suspected resistance to EPA, grower education and remediation.
Additionally, EPA is proposing to limit the registration to five years, which would further provide protections if resistance to dicamba develops.
Comments may be submitted to the EPA docketEPA-HQ-OPP-2016-0187atwww.regulations.gov. After the comment period closes, EPA will review all of the comments and reach a final decision, which the Agency expects to issue in late summer or early fall 2016.
