    "Certainty" by Monsanto claims to kill it without killing Kentucky bluegrass.

    I started this new post because quackgrass is a huge problem with no good solution, and it seems nobody else on this site is aware of it.

    (if you try & it works, you owe me a six-pack)

    Check Monsanto's website for how & when to use it. LESCO sells it.

    It came on the market late last fall, so little is known in field trials.

    Basically -- spray the quackgrass when it's actively growing (spring or fall).

    Follow-up treatments may be needed. It may also yellow out the bluegrass for a short time.

    It comes as a granular product similar to "Manage" in a small plastic bottles.

    Mix it with water as well as a spreader/sticker.

    I'm thinking the quackgrass must be tall, then use a fine mist when you spray it (just like nutsedge).

    Call your local LESCO dealer, and also see Monsanto's website.

    I'm gunna try it soon.

    It might be hard for you to believe Americanlawn, but there are more than a couple people on this site that already knew about it. I'm one of those people. Not bad for a "Senior Member" huh?
    I've already put a bug in my supplier's ear to get some in for me as soon as he can.

    The stuff is not that expensive, about 51.00/acre. You only use .75 oz to .5 oz/acre. After talking to the Monsanto rep I am going to start at the .5 oz rate. and recommend double application plus fertilizing.

    It has been sold in my area for at least the past year.

    Even though it is pushed for the ability to control nutsedge, it is also labeled for controlling Poa and other grassy weeds in warm season turf. We also use it mixed with MSMA for Dallisgrass supression. Versatility is one of the reasons I like the product. There may be better solutions for nutsedge control, but none quite so versatile.

    Since it cannot be used on Fescue, I doubt it will be extremely popular in the transition zone.

    While searching for Certainty I found this link by OSU regarding all new products for turf

    Not on the label.

    And also to the originator of this thread.....the label indicates that it controls bluegrass. The only cool season grass it is labeled for is bentgrass.
