How to kill St. Augustine Grass

jk – posted 15 August 2011 09:12

My husband threw some St. Augustine seed in the middle of our yard about 3 years ago and it has now taken over about a third of our front yard. How can we kill it without killing our bluegrass? We live in the St. Louis, Missouri area.

MSMA is probably the only such herbicide.

The registration of MSMA was cancelled by the EPA on September 30, 2009, and while all uses were terminated in most counties in Florida, however, “After December 31, 2010, existing stocks of products containing MSMA labeled for all uses, except cotton, sod farms, golf courses, and highway rights-of-way and products containing DSMA, CAMA, cacodylic acid and its sodium salt, already in the hands of users can be used legally until they are exhausted, provided that such use complies with the EPA-approved label and labeling of the affected product.”
