Yes the pre emergents discussed by large in here are applicable to Centipede. Spray in the fall right before soil temps hit 55. Use Greencast website to determine this. I use half of the yearly rate during this app. Then in the spring, as the soil temp is approaching 55 again (on the uptick), spray again with half of the yearly rate.

jimbeam did you mean to say 70 F for soil temp in the fall - the temp at which Poa seeds germinate?
