MSMA users give feedback now to EPA

It is extremely important that users of MSMA speak up and make the U.S. Environmental


Protection Agency (EPA) aware of the critical role MSMA plays in responsible and effective


weed management programs.


As part of its ongoing review of MSMA, EPA has agreed to consider input on the benefits of


MSMA and its importance for use on golf courses, sod farms, and highway rights-of-way, as


well as on health effects associated with its use, before the currently scheduled phase out of


MSMA for these use applications, which will take effect on December 31, 2012. Therefore,


your input may be instrumental in EPA’s final decision on this important herbicide. This is


particularly important due to the expanding problem of weed resistance to herbicides other than


MSMA, especially in the Southeastern U.S.


The MSMA registrants believe that there is sufficient scientific information to convince the


reviewers that there is no health concern at the doses of exposure resulting from the relevant


uses, and we believe EPA will extend the registration of MSMA for turf uses beyond 2013


pending sufficient pressure from users.


Concerted pressure from the cotton industry persuaded EPA to re-register MSMA for use on


cotton in 2009. It will take that kind of pressure from users of MSMA on turf — golf courses,


sod farms, and highway rights-of-way — for the product to be retained beyond 2012.


Input to EPA must be received no later than December 31, 2011.
