Product Overview

Only for use in these states: AL, AR, FL, GA, KS, LA, MO, MS, NC, NM, OK, SC, TN, TX and VA.

Dismiss South Herbicide is a selective post-emergent that controls annual grasses, broad-leaf weeds and sedges. Like the original Dismiss Herbicide, Dismiss South kills green kyllinga, purple nutsedge and yellow nutsedge (as well as other common broadleaf weeds) faster than the competition. However, the main difference between Dismiss and Dismiss South Herbicide is that the latter has an enhanced efficacy against purple nutsedge in warm-season grasses. The product goes beyond just attacking the weed on the surface, by penetrating the soil and controlling the sedge tubers. This prevents future outbreaks, reducing the need for re-treats and helping to reduce chemical and labor costs.

Note: NOT for use on St. Augustinegrass
Also, Do Not use Dismiss with a surfactant

    Terrific product.

    By Cwz on 06/20/2016

    Was a little spendy but very effective. After several attempts to get rid of the Texas Sedge that was quickly taking over my tif419 with other products, I went ahead and tried, was brown by end of day, completely dead 3days after. Tif uneffected, no sign of stress.

    Questionable effect

    By Charles on 07/08/2017

    I spot sprayed 2 days after a rain event and there was a brief rain several days after spraying. Air temperature did not exceed 90 degrees for 3 days after spraying. It is now the 5th day after spraying and my centipede grass is severely damaged. It is difficult to assess the effectiveness to the product on the target species (yellow nutsedge) due to the damage to the centipede. I sprayed some purple nutsedge, also. At present the purple nutsedge is still green and alive.

    nutsedge in Phoenix, AZ

    By Molly on 06/06/2019

    This product was very effective in controlling the nutgrass which had been present for years. One spray accomplished most of the control. Total control was accomplished with a second spraying. This was last summer and the nutgrass has not returned.

    Nutgrass and Crabgrass

    By Tracy on 09/27/2019

    Purchased this to get rid of nutgrass and crabgrass since I had a problem with both in my yard. I applied at the minimum rate (10 oz/acre) for application on Bermuda grass. Seemed to work great on the nutgrass. Was turning brown in a week. But not so good on the crabgrass. Crabgrass was my biggest problem. If I had applied at maximum rate (14 oz/acre), it may have done better, but I have 1.5 acres and this stuff is super expensive. One bottle was barely enough to treat my yard one time. Seems to be a good product, but super expensive for the results I got on the crabgrass. I used a 20 gallon pull behind sprayer for application.

Questions & Answers

Have a question about this product?
  
Q
Can I use Dismiss to control Wild Onion growing in a rather large rose garden?

This rose garden is well established and about 1/2 acre in size. Wild onion has infested about 1/4 of the rose garden. If Dismiss will not work, what other alternative is there to get rid of the wild onion short of digging up the roses?

A
Dismiss is only meant to be used on turf and is not labeled for ornamental areas. It may kill the roses.  When treating a weed like wild onions it is best to usually spot treat the onions with a glyphosate or RoundUp type product.  This is the best option.  If that is not an issue, you can use Image 70 DG which is labeled for ornamental areas, but you should try to keep the spray directed at the bed areas and not on the roses.

Q
How much water to add per ounce of Dismiss South?
A
You will need to take a look at the product label as you will not be mixing by the ounce or by the gallon. Dismiss South is a very specific herbicide and the label states when using it on the tolerant species of turf for weed control, you use 9.5-14 ounces per acre, which breaks down to roughly 0.220-0.331 per 1000 sq/ft. When using herbicides the amount of water you use is not what is key, only that you get the correct amount of product over the correct amount of area so as to not harm your lawn by using to much, or not see results by not using enough. The best way to measure out amount per a set gallon of water is to mark off 1000 sq/ft, walk it with just water and see how many gallons of water it takes you to cover that area. Whether its 1 or 5 gallons of water both are correct and you will mix whatever you come up with for coverage with either of the above stated rates. Please let us know if you have any other questions.

Q
Will Dismiss South Herbicide work on Nutsedge, Crabgrass and Buttonweed in 50-70 degree weather?
A

Dismiss South Herbicide will effectively treat actively growing nutsedge and crabgrass when temperatures are between 60-70 degrees, but is not labeled to treat for Virginia Buttonweed.  Blindside would be a better option to treat for all three weeds.
