Dismiss Turf Herbicide is made to control nutsedge and other listed weeds in turfgrass but it is not labeled for use on landscape ornamentals. When treating for nutsedge around ornamentals, most of the time you will have to spot treat where the sedge is coming up with a glyphosate product like RoundUp QuikPro.
According to the product label, Dismiss Turf Herbicide can be safely used to control weeds in the following types of turf grasses:
Bentgrass, creeping (Agrostis sp.), Bahiagrass 2 (Paspalum notatum), Bermudagrass (Cynodon dactylon), Buffalograss (Buchloe dactyloides), Carpetgrass (Axonopus affinis), Centipedegrass (Eremochloa ophuiroides), Kikuyugrass (Pennisetum clandestinum), Seashore Paspalum (Paspalum vaginatum), St.Augustinegrass (Stenotaphrum secundatum), Zoysiagrass (Zoysia japonica), Bluegrass, Kentucky (Poa pratensis), Bluegrass, Rough (Poa trivialis), Fescue, fine (Festuca rubra), Fescue, tall (Festuca arundinacea), Ryegrass, perennial (Lolium perenne)
Please consult the product label for the application rates and timing for your specific type of grass.
Dismiss Herbicide is a very good product that is labeled to kill clover in bahiagrass. The mixing ratio is 0.25-0.375 fl. oz. per 1000 square feet. This will generally mix in a gallon of water. This product is also labeled for various types of other broadleaf weeds, including nutsedge, ground ivy, etc.
There is a disclaimer on the label regarding this product and bahiagrass. There may be a temporary discoloration to exposed leaf surfaces. Treated turf grass will recover with new growth. To reduce the potential for discoloration, do not apply Dismiss to turf grass that is already weak from weather, mechanical, chemical, disease or other related stress. Maintain proper culture practices such as adequate moisture and fertility levels to promote healthy turf growth.
To use the measuring device on Dismiss Turf Herbicide, you would need to unscrew the lid from the product, and insert the measuring tube down into the bottle and screw it securely to the top of the bottle. Once secure, you will gently squeeze the bottle and the product should flow out of the top and collect in the measuring reservoir. Once you have the desired amount, pour into your pump sprayer and remove measuring tube, rinse thoroughly and replace lid. If you are unable to get the product to dispense after following these instructions, please contact us at 1-866-581-7378.
The mixing ratio for Dismiss Herbicide depends on the type of grass you are treating on. For cool season grasses, the rate is 0.092-0.18 fl. oz. of product per gallon of water. For warm season grasses, you will use 0.18-0.275 fl. oz. of product per gallon of water. See the product label for complete application instructions. 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.
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.
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.
