The old TFC or Corsair...I don't think it is still available. Have had good success with Sapphire (sorry don't have A.I. at my fingertips). I would caution though that some biotypes of poa are not tolerant...on my L-93 and A1/A4 Bentgrass, have not seen any damage after spring treatments. Will be starting again soon this fall.
