re: Poa annua in Bermuda

I wouldn’t use prodiamine as your fall pre em. You need to rotate pre ems and prodiamine isn’t super effective on poa. Try a split app of simazine or a single app of specticle. Atrazine will control poa unless it’s resistant. Then you’ll need atrazine and certainty. If your Bermuda is greening up you’d need monument which is really expensive.
