How to kill Bahia grass and not St. Augustine

Hi All, I'm new to the site. I am glad I found it. My problem is, I have a prospective client that looks to have Bahaia grass growing all over his St. Augustine lawn. I am pretty sure it is Bahaia because he used to have Bahaia killed it, and planted St. Augustine. He wants the "weed" out of his lawn. The question is can I get rid of the Bahaia without killing the St. Augustine? How?

I forgot to mention I do home, lawn, and ornamental pest control. I also do Fertilizer and weed control.

Here is a quote from the Texas Turfgrass Association on this topic.

"There is a product called Manor that is supposed to kill bahiagrass. While it shouldn't kill your St. Augustinegrass, it most likely will HURT it and discolor it for a while, and treatment may have to be repeated in 4 to 6 weeks. Unfortunately, bahiagrass is hard to kill. Good luck. "

Image. You can pick it up at your local Lesco. If it were bermuda, you could do a combo Image & MSMA but MSMA isn't one for St. Augustine. You'll probably need to do 3-4 apps, for total control. Plus bahia seeds can last for 5 years, so make sure that you've got a good fert + pre-m program in place. Good luck!

If you are in Coastal Florida check your soil pH. Bahia does not do well or reproduce in high pH. Native soils in the center of the state are low pH.

St Augustine will crowd out Bahia by its self regardless of pH. If you kill Bahia this time of the year you will open it up to winter weeds. If you have plugged a Bahia lawn with St Augustine just be patient. Next summer it will fill in.

Good point Ric. I know that the client has seen and increase in bahaia not a decrease. Could it be that the lawn is being cut too short, and allowing the bahaia to expand? Could it be something other than bahaia? I don't know of any other grass or weed that looks like individual thin blades popping up evenly around the lawn. What I might do, is take a chunk of the lawn down to my local Lesco for inspection.

First what part of Florida Are You? North , South, Inland or Coastal? Soils made a big difference.

Second is this a plug grow in?

Third Yes by all means cut in High High High.

Forth Can this thin blade grass in fact be Sedge?

Fifth Are you licensed as a CPO L&O in the state of Florida??? Fines Start at $ 5000. and go up. You can not throw soap on a Lawn with out a license. No I don't make the laws. Chapter 482 Fla. Law and 5E-1.
