    starting to spread through one of my lawns. rhizomes, hairs, blades look almost like tall fescue but isn't. doesn't grow in bunches and is taller than blue/rye lawn.

    Rhizome in the right picture looks like quackgrass. Tough situation--no selective control product. Prominent in early spring--less noticable later on. Prefers thin lawns.

    I agree with Riggle - quackgrass. Very nasty stuff to get rid of. If you've got large patches hit it with Roundup, rake out the dead remains and reseed. For small patches let it get tall and wipe on the Roundup. Quack grass thrives in thin turf. Getting the turf healthy and thick will prevent
    it from coming back.

    Good luck... I dread quack grass.

    Uh huh...wick applicator or a sponge (& rubber gloves) with Roundup. Check the Rup label for the higher "wick applicator" rates.

    Look for clasping auricles. Definitely Quackgrass if it has clasping auricles. Hopefully Tenacity will labeled soon for home lawns.

    I don't see Quackgrass on the Tenacity label.

    I was my understanding it does control Quackgrass. I have not read the label, just something I heard.

    I hope your right. From the label Tenacity looks like a good product for cool season turf. And if it controls Quack Syngenta hit a home run.
