Dismiss Turf Herbicide controls difficult weeds such as yellow nutsedge, purple nutsedge and green kyllinga in as little as 24 to 48 hours! No other nutsedge killer on the market gives you visible results in as little time as Dismiss Turf Herbicide from FMC. Dismiss Herbicide is faster than Image, Certainty or Monument Herbicides. Dismiss herbicide can be absorbed into foliage, but most of the product is delivered to the plant through the root system. Dismiss is gentle and well tolerated on most warm and cool season turf grasses.
It is NOT recommended to use a surfactant with this product.
This selective post-emergent herbicide controls nutsedge and weeds in turf sites including residential and commercial lawns, athletic field, commercial sod farms, golf course fairways and roughs.
Post-Emergent Control of Annual, Biennial & Perennial Broadleaf Weeds
Dismiss Turf Herbicide will control or suppress the weeds listed on the label when applied alone shortly after weeds have emerged. Apply Dismiss Turf Herbicide at rates from 4 to 12 fl. oz/acre (0.092 to 0.275 fl. oz./1,000 sq. ft.). Do not exceed the application rate specified for the turfgrass species on the label. To broaden the weed spectrum and increase effectiveness for certain weeds listed on the label, Dismiss Turf Herbicide may be tank mixed with other EPA registered post-emergent herbicides. Read and follow the Tank Mixtures Compatibility section of this label to determine compatibility of tank mixtures. Read the label recommendations of the tank mix partner to determine turfgrass species safety, use rate and application procedures. Follow all label restrictions, use directions and precautionary statements before using these tank mixtures. Control of emerged annual grass weeds may be improved by combining Dismiss Turf Herbicide with other registered post emergence herbicides.
Post-Emergent Control of Annual and Perennial Sedges
Dismiss Turf Herbicide will control or suppress sedges listed on the label when applied at a rate of 4 to 12 fl. oz./acre (0.092 to 0.275 fl. oz./1,000 sq. ft.). Apply the highest rate consistent with the rate needed for turfgrass safety on the label. Rates lower than 12 fl. oz./acre (0.275 fl. oz./1,000 sq. ft.) will generally control sedges for at least 60 days. A rate of 12 fl. oz./acre (0.275 fl. oz./1,000 sq. ft.) will provide approximately 75% control for at least 60 days.
Purple Nutsedge; For optimum control of purple nutsedge, split applications are recommended. Apply 4-8 ounces per acre as an initial application followed by a second application when evidence of actively growing purple nutsedgeis visible. Do not exceed the maximum rate per acre based on turfgrass variety listed on the label - Tolerant grasses.
Post-Emergent Control of Grassy Weeds
Dismiss Turf Herbicide will control or suppress specific annual grasses listed on the label when applied at a rate of 4 to 12 fl. oz./acre (0.092 to 0.275 fl. oz./1,000 sq. ft.). Apply the highest rate consistent with the rate needed for turfgrass tolerance listed on the label. Rates lower than 12 fl. oz./acre (0.275 fl. oz./1,000 sq. ft.) will generally control grasses for at least 60 days. Dismiss Turf Herbicide works best if applied when the annual grasses are small (pre tiller stage) and actively growing.
Good spray coverage is needed for optimum control of grasses. Temporary discoloration of some turfgrass species may result from use of surfactant. Use of surfactants is not recommended.
Selective Weed Control in Container and Field Grown Ornamentals
Apply as a directed spray toward the base of the plant. Do not spray over-the-top. Dismiss Turf Herbicide is most effective when applied to soil free of clods and debris such as leaves or mulch. When applied as a pre-emergent, the treated area should receive at least 0.25 inches of irrigation or rainfall after application for the greatest efficacy.
The addition of liquid fertilizers can increase the probability of superficial damage to green plant tissue inadvertently treated if applied with Dismiss Turf Herbicide.
Dismiss worked great using a portable sprayer. I mixed the solution at a rate of .275 oz per gallon. This mixture was applied to many sections of my yard where weeds were growing mixed in with grass. The treatment was applied around a temperature of 90F degrees. I do not recommend applying at temperatures above 90F.
Some weeds got weak in 24 hours and most showed signs of damage by 48 hours. For some weeds it took 1 week for the real effect to show up. My St. Augustine grass showed no signs it had been treated at all. The weeds died but the grass was unaffected. After treatment the grass has really started to take off.
The product comes with a add on filler tube, similar to pest control mixtures, where you can accurately and safely measure the amount of product being added to your mixer. Be sure to shake up your sprayer every 10 minutes to ensure the mixture stays consistent.
I applied the mixture to the yard in more of a spot treatment process than covering the whole yard. Why spray weed free grasses that are not the target? The treated section should just get wet. There is NO need to soak the ground. This product is a contact product so the roots are not the target, it is the plant above ground.
Best effect was on nutsedge. Showed significant yellowing and weakness quickly. Worst effect was some form of clover. It took 2-3 weeks to show signs it was dying. We have about 15 varieties of weeds in our yard and this product killed them all. It did take a second treatment on the crab grass to fully kill it.
The cost of this product seems high, but it will save you hundreds versus yard spraying service people. I decided to use my pest control experience on my yard after some clown showed up and killed most of our yard with improperly applied chemicals. Do yourself a favor and fire your yard service before they kill your lawn and leave you with just weeds. Do it yourself when you want to, how you want to, and save money in the process!
Went to my local flower seller. They sold me "Sedge Hammer." Required a product to help it stick to the plant. Between the two products: $35.00.
Did an experiment: while not scientific, it told me what I needed to know. I sprayed one side of my driveway with "Dismiss," and the other side with the local product.
It was amazing! Following the instructions to a 'T' on both products, the Dismiss side was dead and withered within 4 days. The local product showed no change. After two weeks, the local product made the sedge plants look sick-yet still green and present in my yard.
I am sold on Dismiss for a rapid removal of this pest. I have been trying to rid the lawn in these areas for years. I now think I have the answer: Dismiss. Worth every penny.
Had been using Sedgehammer on Yellow Nutsedge for couple of years (with surfactant); was generally successful but took several weeks to show effect. Sometimes did not work; perhaps because I occasionally held unused quantities over for several days, then using the remaining portion?; or maybe not. Blogs note Sedgehammer must be used within 4 hrs of mixing or it loses effectiveness. Seeking more responsive control, tried Dismiss, using only as a spot spray at .0275 per 1.5 gallon water. Killing effect seen in 48 hrs. Discoloration of grass seen in sprayed area(s), but this disappeared within 7-10 days. I will reduce dose in future to see if discoloration persists.
I hate nutsedge and have tried everything to get rid of it, even using RoundUp which killed my entire back yard. I have been on hand and knees with a water color brush painting it with Roundup. I have used Sedge Hammer which was fair. Now I am delighted to report that Dismiss actually works! I am thrilled. Nutsedge loves this dry hot weather and I have practically eliminated it (I missed some with my spraying). I am telling all my friends and neighbors. Expensive, but well worth it.
Our lawn guy recommended this product. He charges almost $200 for one application. I purchased the product myself, and he told me the mix ratio and I applied to my lawn myself in a 1 gallon pump sprayer. The stuff works...just make sure you apply enough on the areas. I missed some spots, so I need to re-apply. But where I did do a good job of applying...no more nut sedge weeds. I recommended your site to a co-worker so he could purchase some for his lawn.
How much Dismiss is recommended per gallon (tank sprayer) for spot treatment?
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.
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?
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.
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?
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.
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.
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.
