Dismiss Turf Herbicide - Questions & Answers

Dismiss Turf Herbicide comes in a bottle that contains 6.0 ounces of concentrate, which will cover 0.5 to 1.25 acres, depending on the weeds you are treating and the turf. Many professional herbicides will come in a size that will cover an average of one Acre (43,560 sq ft). It is important to keep in mind that your water is just a carrier, and how much water is needed to get uniform coverage will vary with your equipment and the speed at which it is moving. Therefore, it is hard to estimate exactly how many gallons of water will be used when you are covering a large area. You can break down the rate of 4-12 ounces per Acre to 0.092 to 0.275 ounces per 1,000 square feet, using adequate water to get thorough coverage of the area using your equipment.

Dismiss Herbicide will control more weed species than the Prosedge, however it may be easier to use a product like Prosedge if you only have a small area to cover.

When used as directed, Dismiss Turf will not harm established shrubs or trees if they are accidentally sprayed during application. Since this is a broadleaf weed herbicide, you should not apply Dismiss directly to ornamentals or ornamental beds.

The product label for Dismiss Turf Herbicide does not list liriope, monkey grass, or mondo grass as tolerant to Dismiss applications. Because the label specifically indicates that applications should not be made to ornamentals, we believe that the Dismiss could harm the liriope. We do sell many herbicides that are labeled for weeds around ornamentals or to kill the liriope, but we would need more information about your situation to give an educated recommendation.

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.

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.

Dismiss will not control Bahiagrass in St. Augustine. St. Augustine is very fragile so it is very difficult to control Bahiagrass in it.  Blade is labeled for use in St. Augustine but there are some conditions for this application.  The grass needs to be well established and healthy and you cannot spray when it is over 85 degrees.  You should use a ½ ounce rate per acre of Dyneamic Surfactant with the Blade, and a second application 4 weeks later if the Bahia is still growing.  Blade can stunt St. Augustine if the grass is not strong, so adding a good foliar fertilizer with the application is good to do.  Coron 28-0-0 + Turf Nectar well help the St. Augustine grass overcome this.

Tolerant cool seasons grasses are : Creeping Bentgrass, Kentucky Bluegrass, Rough Bluegrass, Fine & Tall Fescue, Perrenial Ryegrass. No product should be stored in an area where it can freeze or get too hot. Insecticides and herbicides need to be stored in a temperature stable environment out of direct sunlight to sustain the longest shelf life and strongest potency of the product. A product that is safe on several cool season grasses and will cover broad leaf weeds as well as grassy weeds and Poa Annua would be the Echelon 4SC. Echelon 4SC is a selective/post emergent product like the Dismiss but better suited to your needs. You can review the product label for dilution rates for your type of yard.

Hi Dan,

Yes, I would do at least one mowing before applying Dismiss.  Then wait about 3 days before spraying and allow at least 3 days after spraying before mowing again.  This will make sure the grass and weeds are actively growing for the most weed control absorption.  Please let me know if you have any questions.  

Thanks,
