    Q
    Need to control weeds in my Floratam lawn. Nutsedge, Virginia buttonweed, and crabgrass are the worst. Can I use Certainty?
    A

    Certainty Herbicide would not control crabgrass.  Blindside would be a better option for the listed weeds and is safe on Floratam.  Image Kills Nutsedge is another option for smaller lawns.

    Q
    Question about Certainty herbicide. Can it be mixed with Pendulum 3.3 without compatibility issues?
    I've done this with Prodiamine before but not with an EC.
    A

    Certainty Herbicide - 1.25 oz. can be tank mixed with Pendulum 3.3 EC following each labeled instructions and rates.  Certainty would be added first than the liquid herbicide.  Before tank mixing, a simple jar test is recommended to insure compatibility of herbicides as directed on the label.

    Q
    can certainty kill annual poa in a tall fescue lawn
    A
    While Certainty Herbicide is labeled to treat Poa Annua, it will also kill your Fescue lawn. Instead, you could use Bensumec 4LF on Fescue turf. Bensumec 4LF is a pre-emergent broadleaf herbicide that provides season-long control of broadleaf weeds in all major turf grasses, including Fescue.

    Q
    Can Certainty be tank mixed with prodiamine?
    I applied an application of prodiamine in early march (NC) on my zoysia. I had some poa come through in some spots and would like to kill it and further prevent anything else coming up. If they can be tank mixed, how long should i wait to water in the prodiamine?
    A

    While Certainty and Prodiamine can be mixed together with no issue, Prodiamin is only going to prevent spring germinating weeds from coming up and only if you are getting it down prior to soil temperatures reaching 50-55 degrees as that is when seeds germinate. Also, poa annua is a fall germinating weed so a spring application will not prevent anymore of it coming up. You would need to use something like the Prodiamine in the fall around Sept-Oct 15th to effectively prevent it the next year.

    A

    Certainty is only labeled to be used in woody ornamental plantings and perennial groundcovers.  It may harm flowers if they are sprayed or drift contacts them.  Care should be taken to avoid this and only use as a spot spray directly to the nutsedge in this area.  It is not labeled to treat plantain.

    Q
    Will Certainty kill Poa Trivialis present on my primarily Bluegrass lawn?
    Without killing the grass. If not any suggestions
    A

    Certainty Herbicide - 1.25 oz. cannot be used in cool season grasses and will harm them.  We are not aware of any product labeled to control poa trivialis in a bluegrass lawn.  In your case it would be best to spot treat the poa with a glyphosate based product such as GlyPhoSel Pro and reseed the area.
