| I have a heavy infestation of poa trivialis (as best I can determine) I plan to kill off in prep for redoing lawn this fall.
Any recommendations for what's best to use? |

| RoundUp is very effective but any product with the same active ingredient (glyphosate) will work. |

| Round up is going to cost you 50% + or more than other brands. As Grass1950 said, any of the glyphosates at 41% or higher are the same thing but cheaper. You also want to look for stuff with a surfactant, if not adding a little dish soap works. I use Pronto Big N Tuff and get it at TSC for $49 for 2.5 gallons. Prior to knowing any better, I use to use round up at $21 a quart. |

| One point, glyphosate is non selective and will kill anything that gets sprayed. There is a product called Tenacity? that supposedly will kill triv and not other grasses but results are varied and it is extemely expensive. |

Thanks for the tip on surfactant. I had forgotten that little gem. I have used other brands of glyphosates before and always buy the concentrates.
Not being patient (a big downfall of mine), I was hoping there was something I hadn't tried that worked overnight... |

| Something super fast like that is not beneficial. It often happens by just burning the foliage so fast, but does not penetrate to the root system resulting in re-grow. A regular does of glyphosate makes its way slowly through the entire plant, killing it off for good. (until other seedlings sprout) |
