    Q
    Do you know if Dismiss is rainproof and if so, how soon after I apply?
    I've read the label and can't find any information about whether Dismiss is rainproof and how much time is needed before watering my grass again. I'm also not sure if I should water this treatment into my grass to help. Any ideas?
    A
    You do not have to water in Dismiss after application since you are applying it with water already.  If you can go 24 hours before watering then that would be ideal. Dismiss will be rainfast 4 hours after application.

    Q
    What time of year can we apply Dismiss Turf Herbicide? Is it a pre emergent and a post emergent?
    Can this be used as both pre emergent and post emergent product?
    A
    Dismiss Turf Herbicide is a selective post only emergent product that is meant to be used on sedge and kyllinga weeds.  It is labeled for most warm and cool season turf grasses.  Since this is a post emergent product, you should apply it whenever you see signs of sedge or other weeds as permitted on the label.  You should always read the label first to make sure it is ok to use on your type of grass. Here is a link to the Dismiss Turf Herbicide product label.

    Q
    How do I mix Dismiss for a tank sprayer or a hose end sprayer? What is the dilution per gallon?
    I have 1 acre of fescue for home residence.
    A
    The reason that herbicides do no list a specific amount per gallon of water is because the dilution rate is different for everybody.  It depends on what equipment you are using.  The more important thing is how much of the product is placed out over 1000 square feet. 

    When applying herbicides, we always recommend using calibrated equipment, rather than hose-end sprayers, to avoid uneven application or damage to desirable plants. Most herbicide labels will list how much active ingredient should be used per 1,000 square feet. To calibrate your equipment, for example, a 1 gallon sprayer, mark off an area of 1,000 square feet, and cover that area at your normal pace as evenly as possible. If you used the entire gallon, you would use the recommended amount in 1 gallon of water. If you only use ½ gallon to cover the 1000 square feet then you mix the recommended amount on the product label in a 1/2 gallon of water.  So if an acre is basically 44,000 square feet and the product label calls for 5 ounces per acre for fescue, and you used 1 gallon to cover 1000 square feet, then you would mix 5 ounces of Dismiss in 44 gallons of water.  Ultimately, correct timing and application rates are more important than how much water is used to apply your herbicides.

    Q
    How soon after applying Dismiss is it safe to let my dog on grass
    A
    You would need to keep your dog out of the treated area until it has a chance to fully dry. Once it has dried complete, maybe a couple of hours, then it is safe for your dog to re-enter the treated area.

    If you only need a small amount of product to control purple or yellow nutsedge, then you may want to consider Sedgehammer Herbicide, which comes in individual packets that can be diluted in 1 gallon of water at a time.

    Q
    Can you spray Dismiss Turf Herbicide before you lay sod?
    can you use this before you lay sod? using this on flortam sod
    A

    Dismiss Turf Herbicide should only be applied to established sod, generally at least 3 months after installation and not within 3 months of harvesting new sod, per the product label. Keep in mind that Dismiss may cause temporary discoloration on sensitive grasses such as Floratam. Since this is just a post-emergent herbicide, it would not be applied to bare ground before sod is installed.
