Dismiss Herbicide
Dismiss Herbicide
Dismiss Turf Herbicide, manufactured by FMC Professional Solutions, is a selective post-emergent herbicide for control of a variety of broadleaf weeds and sedges in healthy turf areas.
This product is a flowable (suspension concentrate) containing 4 lbs of active ingredient per gallon. The mode of action of Dismiss herbicide involves uptake by both weed roots and shoots.
Not only does Dismiss Herbicide attack the surface of the weeds but it goes even further, getting into the soil to penetrate the sedge tubers. This penetrating soil action helps to prevent future outbreaks of sedges.
Tools Needed
To use Dismiss Herbicide, you will need either a handheld pump sprayer, backpack sprayer, or spray rig. For small lawn jobs, we recommend a handheld 1-gallon pump sprayer or a 4-gallon backpack sprayer.
How to Use
- Step 1: Determine how much Dismiss Herbicide you need by calculating the square footage of the treatment area. To do this, measure and multiply your lawn's length x width to get the total square footage to be treated. Dismiss should be mixed at a rate of 0.18 to 0.275 oz. per 1,000 square feet in 0.5 to 4 gallons of water on warm-season grass or at a rate of 0.092 to 0.18 oz. per 1,000 square feet in 0.5 to 4 gallons of water for warm-season grass.
- Step 2: Fill your selected spray tank a 1/4th of the way with water and then add the appropriate amount of Dismiss Herbicide. Fill the sprayer the rest of the way with water and shake well and you are ready to spray.
- Step 3: Spray target weeds until wet but not to the point of runoff. A good technique to put into practice is to avoid side-to-side movement of the nozzle when spraying as it is best to spray the nozzle directly with no movement close to the weeds to ensure proper application.
Where to Use
Dismiss Herbicide is for use in and around commercial and residential turf including golf courses, lawns, sports fields, cemeteries, parks, campgrounds, recreational areas, roadsides, school grounds and sod farms.
When to Use
Apply Dismiss Herbicide on mild days when wind speeds are low to minimize drift. It is best to apply Dismiss when turfgrasses are under minimal stress and not weakened by weather, mechanical, chemical, disease or other related stress. For most effective results against most weed species, time your application when the weeds are young and actively growing. For longer residual control or heavier sedge populations, a second application 30 days following the first may be needed for optimum control.
Safety Information
Dismiss Herbicide is safe to use around children and pets when applied according to the product label instructions. Always wear the appropriate personal protective equipment (PPE) when handling and applying this product.
Do not allow people and pets to enter treatment area until spray has dried.
Special Considerations
The use of surfactants is not recommended with Dismiss Herbicide.

Q:Spray with dismiss kills it but it comes back in same spots the following year?10/1/23A:Dismiss Herbicide is a post-emergent herbicide meaning it will only kill weeds that are above the ground for up to 60 days. You will need a pre-emergent herbicide to kill any weed seeds growing under the soil, which is why you are seeing in the same spots the following year.

Q:How does dismiss work?6/1/20A:Short answer? You mix it according to the label, spray it on the weeds you want gone, and the Sulfentrazone kills the weeds. Easy. Long answer? Dismiss active ingredient is Sulfentrazone. It controls weeds by disrupting membranes and inhibits photosynthesis in plants commonly known as PPO (Protoporphyrinogen oxidase) Inhibition. Sulfentrazone is received in the plants through the roots of the plants. As the plants come out of the soil , they die after exposure to light. It also works as a foliar contact causing rapid desiccation or removal of moisture from the plant, in essence - "burning" the plant.

Q:how long after application can I reseed with fescue?8/21/18A:Application to reseeded, overseeded or sprigged areas: Reseeding, overseeding or sprigging of treated areas within one (1) month after application of this product could inhibit the establishment of desirable turfgrasses. Overseeding of bermudagrass with perennial ryegrass at two (2) to four (4) weeks after an application can be done if slight injury to perennial ryegrass can be tolerated. Best results are obtained for reseeding or overseeding when mechanical or power seeding equipment (slit seeders) are used to give good seed to soil contact and proper soil cultivation, irrigation and fertilization practices are followed
