    This is pretty prevalent in one yard this year. It tends to grow in groups or clumps like above. Cant say Ive seen it before. Any ideas? Thanks in advance!

    Your pics are a little lacking due to no view of the roots, but it looks like barnyardgrass. Most any quinclorac-based herbicide (Drive XL8R etc) should smoke that in no time, unless you have a resistant strain -- in which case napalm should take care of it.

    Agree, and it doesn't matter what it is specifically, because it is a clearly a grassy weed. Needs treatment by quinclorac if there is too much to dig/pull/out manually.

    Just wondering
    Did the homeowner by chance set out bales of wheat straw in the lawn last fall and set pumpkins and stuff on them for Halloween and Thanksgiving?

    Wouldn't barnyard grass apear in fall and go to seed the same time as crabgrass?
    A grain due to straw that was used is a possibility.

    What do you use for Cheatgrass? Saw it on simazine label, what other products would you use?

    Not only does it appear at homesites, it also is used along ditchbanks, right of ways and mostly (around here) on newly prepped overpass easements. I visited 5 newly developed subdivisions yesterday. All of which is in old pasture land......low flat plains, wide open vista's. All weedy material that is closely related in appearance to the weed in question.
    I will repeat, if this stuff is in a new home site, it is because the site was seeded at the time of pre construction to keep down erosion, then the homebuilder or developer decides to sod the mottled ground for better sales. With the expense at stake and less prep work involved, the sod is laid right over existing weeds. Eventually the weed wins the fight until the new turf grass takes root.
    As far as the weed by name..........can't see much other than seed formation.
