Poast is the AG label version of Sethoxydim. What you want is Segment, the Turf label version. That has a label for application of 2.25 pint per acre to centipede grass with a limit of 2 treatments per year. Celsius by itself will yellow and damage dallisgrass. However, for commercially acceptable control, either Monument or Revolver herbicides need to be tank mixed with the Celsius and neither of those products are safe on centipede.
They who can give up essential liberty to obtain a little temporary safety, deserve neither liberty nor safety.
Benjamin Franklin 1775
Sell not virtue to purchase wealth, nor Liberty to purchase power.
