    I only got two rounds down at two week intervals using 4oz/a rate, it has really supressed the pt. I wished I could have gotten the third round down though. Rained for two weeks when third app was due. I am going to continue with two more rounds this fall with turflon added. My last spay was May 8th. I would estimate it has reduced the population of pt to 20% of what it was prior to spraying. My lawn looks much better. I have been seen some fine grass coming back which I suspect is pt but it shouldnt do well during this warmer and dryer weather. I think over a period of time tenacity my eliminate most of the PT.
