There are no alternative selective postemergence herbicides other than organic arsenicals available for control of mature crabgrass and tropical signalgrass weeds.


The MAA Research Task Force has announced that it disagrees with a proposed Re-registration Eligibility Decision document issued by the U.S. EPA regarding the organic arsenicals MSMA, DSMA, CAMA and cacodylic acid.

Members of the task force include Drexel Chemical Co. (APC Holdings), KMG-Bernuth Inc. and Luxembourg-Pamol Inc. These companies are global providers of products to the turf care industry.

The Task Force believes that crop and turf uses of these products meet both the Food Quality Protection Act standard for dietary risk and the Federal Insecticide, Fungicide, and Rodenticide Act risk-benefit standards, and thus warrant continued registration

MSMA/DSMA/CAMA control certain weed problems in cotton and turf like no other herbicides. For example, there are no alternative selective postemergence herbicides available for control of mature crabgrass and tropical signalgrass weeds.

Based on a large body of scientific data, the MAATF believes that the organic arsenicals do not pose an unreasonable risk to workers, farmers, the public or the environment when used according to label directions.

Because the Re-registration Eligibility Decision is not a final decision, farmers, turf managers, and home owners may continue to use organic arsenicals on all currently registered crops and uses.
