    Bentgrass leaves are mostly less than an inch long. Slender, long rhizomes. Raking pulls out big clumps.
    I think Kerb is right.

    Sorry I should have had a scale, these leaves are longer, this plant does not have that signature 'puff ball' of leaves at the end, which is why I did not think bentgrass this time. I will get a better picture

    There is some chance that it could be Agrostis gigantea (Redtop). Control is the same as creeping bentgrass according to Turfgrass Weed Control for Professionals published by Purdue Extension, a publication I purchased.

    Now that I’ve looked it up, I think I may have some of that in my lawn. I used to think it was just creeping bentgrass.

    There isn't very much information available on line, but here is one link:

    Yours may not be redtop after all, redtop spreads by rhizomes and yours looks to be stoloniferous, though field differentiation of stolons and rhizomes can be difficult.

    Check and see if it has tall ligules, that may indicate that it is in the Agrostis family and can be treated like Agrostis.

    excellent, thanks for the good info, I will work on trying to confirm if it is indeed redtop.

    Looks like nimblewill. If it is only Tenacity herbicide will take it out.
