I don't use prodiamine on centipedegrass for a couple of reasons:
1) Prodiamine is a root inhibitor and hangs around in the soil a long time. So, it keeps the roots from spreading stolons from tacking down and creates stolon hoops or wickets.
I've seen competitors sued b/c some old lady got her foot caught in a centipedegrass stolon that didn't root down b/c of prodiamine app. Most of the cases I've heard about were dismissed, but that's a battle I'd rather not fight.
2) I always see at least some winterkill on centipedegrass every year, even in the southern coastal parts of SC and GA. B/c prodiamine hangs around so long and inhibits root activity so much, you can't repair those areas if something doesn't come back from the winter cold.
Prodiamine is a great product -- it does a great job of keeping weeds from establishing. Centipedegrass is a finicky animal and, while prodiamine keeps the weeds away, it also makes it difficult to repair any damage that can come from cold winters.
