Pam from Sebring, Fl writes

Is Southern Ag Atrazine Weed Killer for St Augustine Grass effective to remove carpet grass growing in St Augustine Grass?

Answer:

Southern Ag Atrazine Weed Killer for St Augustine Grass is not labeled to treat carpetgrass. Unfortunately, we do not have a selective herbicide to kill carpetgrass in another turfgrass. You can use a non-selective herbicide such as RoundUp QuikPro to spot treat the carpetgrass and then reseed or resod as needed in any bare spots.
