I'm thinking of spraying simazine on bermuda grass in GA for Poa. I sprayed this past Oct but I think because of the rain we had here there was some Poa break thru. I don't normally spray simazine now. But just wondering if I did, Would this delay spring green-up in my bermuda grass this year? I just need to spot spray some areas that had some break thru. Really not many yards. Any opinions..
