Is there a substitute for "MSMA"?

I'm trying to kill st. augustine which is invading my emerald zoisia.

Answer:

Two products we carry that have an active ingredient closest to MSMA are Quali Pro MSM 25 OD Liquid Herbicide and AmTide MSM 60 DF Herbicide. St. Augustine grass is labeled as a tolerant to both of these products though, as well as Emeral Zoysia. Your best option though, will be to spot treat with Roundup. St. Augustine and Zoysia are closely related so whatever is safe for Zoysia will likely be safe for St. Augustine as well.
