Children can return to the yard as soon as all areas where Tenacity Herbicide was applied have fully dried.
Tenacity Herbicide calls for 5 to 8 oz of per acre, unless treating St. Augustine turf grown from sod, you would use 4 oz per acre. If you plan to use Tenacity at low rates of 5 oz per acre then you would use 0.11 oz per 1000 sq/ft or 0.45 oz per 4k sq/ft. If you want to use the high rate of 8 oz per acre then you would use 0.18 oz per 1000 sq/ft or 0.72 oz per 4k sq/ft. Be sure to use at least 1 gallon of water per 1000 sq/ft that you treat, and mix your non-ionic surfactant into the tank at the rate of 2 teaspoons per gallon of water. Spray foliage of target weeds until wet but not until the point of runoff. If a reapplication of Tenacity is needed, you can reapply after 2-3 weeks from your initial application.
Tenacity Herbicide is safe to use in a yard where pets and children will frequent as long as they are out of the area during the application. They can safely return after the area has dried, typically at least 4-6 hours after application.
As long as you are not applying over the well and keeping applications at least 15 feet away from the well, Tenacity Herbicide can be used if you have well water.
You can view the full list of weeds controlled by Tenacity Herbicide on page 3 of the product label here. There are separate colums for pre-emergent and post-emergent control.
We do always recommend that only mix the amount of Tenacity Herbicide you can use at a time. To dispose of any remaining you would not pour down any drain, but can use to go over some of the areas you were treating or you can pour into the dirt right next to the foundation of the home to prevent any run off to the nearby creek.
Pre-Emergents typically should be applied in the spring before ground temperatures reach 55 degrees and again in late summer/early fall. For more specific recommendations based on the current climate of your region we would recommend contacting your loacal Master Gardener.

Tenacity is an effective herbicide for weed control prior to or during seeding of certain turfgrasses during turf renovation. Please see section on use in New Seedings in the Product Label for complete instructions and limitations for your specific turf type.
Tenacity Herbicide? would be a great option for you to control crabgrass, along with many other common weeds, without harming your Centipede lawn. Tenacity needs to be tank mixed with a non ionic surfactant? or the best results and stick to the leaf surface of the weeds, and its advised to use a dye like Turf Mark Blue? with it so you can make sure to not overlap if you plan to do a broadcast application on the property. According to the Tenacity product label you will need to mix 1/2 tsp of product + 1 1/2 tsp surfactant with 1 gallon of water for spot treatments. After spraying with Tenacity Herbicide, the foliage of treated weeds cease growth after application, then turn white (loss of chlorophyll), and death may take up to three weeks. A repeat application is required after two to three weeks for improved postemergence weed control.

Per the label of Tenacity Herbicide, the lawn can be reseeded at any time unless the grass type is fine fescue. You will not need to remove the dead weeds from the area first.
Mowing before applying Tenacity Herbicide is not required but if you are going to do so be sure to mow 2 days before applying or wait 2 days after.
According to the Tenacity product label for smaller applications, you will need to mix 1 tsp of Tenacity and 3 tsp of surfactant to 2 gallon of water, using 1 gallon each to cover 1,000 sq ft. Be sure to check the product label to ensure proper rates for your turf type and target weeds are being used to get the best results.
In general, we would recommend killing the undesirable plants and clearing out the dead plant debris before dethatching and then reseeding the lawn. Dethatching will be easier and you will get better germination with your new seed when the ground is better prepared for it. You can learn more about these treatments in our Do My Own Lawncare Video Series, too. You can find them on the bottom of our Lawn Care Guides page here.
You can mow 2 days prior to application and 2 days following application of Tenacity Herbicide.
As you probably know, Centipedegrass is a very sensitive species of turf so many products that eliminate the crabgrass and other weeds can also cause damage to your lawn. Tenacity is a great pre- and post-emergent herbicide that will control crabgrass along with many other types of weeds without harming your centipede lawn. Make sure to read the Tenacity label very carefully and mix exactly what is recommended as this is a strong product and mis-using it can cause temporary turf injury. When applying Tenacity it is highly recommended to use a temporary turf colorant like Turf Mark Blue to allow you to see where you are spraying. Overlapping your application of Tenacity can cause temporary whitening of the lawn as well, but the color will return in 3-4 weeks at most. Please let us know if you have any other questions.
According to the Tenacity product label you will need to mix 1 tsp of product + 3 tsp surfactant with 2 gallons of water for spot treatments. You will not apply more than 5-8 ounces of Tenacity per acre as a broadcast application. Please click on the product label link for mixing and applications according to the type of turfgrass you have.
You should wait until the newly germinated turf has been mowed two times, or four weeks after emergence (whichever is longer) before making a postemergence application with Tenacity if it was not applied at the time of seeding.
Wiregrass is a form of bermudagrass. The product label states that bermuda grass is sensitive to Tenacity but it would not be recommended as a product specifically used to kill it. Fusilade II can be used to get rid of bermuda grass in tall fescue. Please be advised that bermuda grass is extremely difficult to control and you will likely need to make several applications.
