    Red thread fungus in the lower left of the photo, LOL! Also henbit in lower center, LOL! Too early for nutsedge--which needs temps of about 85. Orchard grass is a possibility--grows in clumps--has flat stems, check that.

    Notice that "Segment" is listed for "Orchard grass, seedling"--which essentially means it does not work on orchardgrass.
    Annual ryegrass has red coloration at the soil line, and leaves are glossy. Check that in second photo.

    I'm thinking that its annual ryegrass. It seems to have the pale color and coarse texture of annual ryegrass and the annual rye would be growing pretty tall at this time of year. Perennial ryegrass is usually finer textured and doesn't seem to grow as quickly in late winter.

    It will die with the warmer temps after it sets seed. Or, you can take it out with just about any SU labeled for ryegrasses (Revolver, etc).

    Ted nailed it....Orchardgrass. Leaf blades have a slight curl to them and the weed has a blue/green color to it. Matt

    We have had a real mild winter again this year up to today! Ice on the ground now and still coming down and 27 degrees out.

    The 2nd picture is a good one / this is annual rye grass the reddish sheath gives its 1st characteristic away, the waxy leaf underside, semi clasping auricle, bud vernation is rolled and its bunch type habit (short stolons & rhizomes) are the identifiers.
    The summer heat will bring its end but you won't want to wait that long, roundup then seed in the desired type of turf. No selective science exists yet.
