Bahia Grass (aka-Highway Grass) Infestation this year!

I've always fought against it but it seems like this year it's taking over. I've heard it thrives in dry or drought-like conditions which explains one part of my yard, but it's completely taken over there and I'm tired of fighting it.

I've got a mix of grasses thanks to neighbors going with different types so I need to be careful with how I control it. From the research I've done, it looks like I need to mix:

Metsulfuron - Which controls Bahia but is friendly for St. Aug, Bermuda, centipede and zoysia as well.

Herbicidal Surfactant - To help the herbicide stick to the treated area better.

Post-Control Marking Locator - A safe blue-coloring that will help me determine where I've applied the herbicide.

Is this overkill? Am I overlooking a simpler method with no mixing/spraying required? Something I can perhaps use my mixer for?

Obviously I don't want to use Round-Up as this is gonna destroy my grass in several spots, and even though the weed is crowding it out it'd still come back in a hurry if I got control of the weeds.

Tell me what y'all think.
