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.
As he said centipede is sensitive and prodiamine is one of the harshest root pruners. Not sure about your timing of simazine but I am going to put mine down if Nov. I'm located in south Arkansas if that helps.
