MSMA is an old herbicide that was sold for both the professional market for postemergence broadleaf and some grasses control in turf. It was also available in the home use market primarily for crabgrass management. However, because one component of the herbicide is arsenic the use of MSMA has been greatly restricted, primarily due to groundwater concerns. It is currently only allowed for use in cotton and limited use on golf courses, sod farms and highway rights of way.
