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.
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.
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.
Tenacity Herbicide should be used when the temperatures are consistently above freezing on a daily basis. Your target temperature range will depend on whether you are using Tenacity for pre-emergent or post-emergent applications. Please consult the product label for complete application instructions.
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.

Tenacity Herbicide may be applied when soil temperatures are around 55 degrees or higher. Do not apply when air temperature exceeds 85 degrees.
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.
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. Please click on the link below and select the region in which you reside to find the contact information for your local Cooperative Extension Program office.

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.
You can mow 2 days prior to application and 2 days following application of Tenacity Herbicide.
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.
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.
Tenacity will keep for 3-5 years from the date of purchase if stored away from extreme temperatures. If yours was purchased in 2013 it may still be good. You may wish to contact the manufacturer directly to see what they recommend. You can reach Syngenta by calling 800-334-9481.
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.
Yes, when using Tenacity Herbicide as a post-emergent herbicide you would add a non-ionic surfactant to the water mix.
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.
Tenacity Herbicide could pose a discoloration if it gets on the bark. You want to try and make the application on a day that is not very windy. 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. Tenacity will also act as a pre emergent for listed weeds.
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.
Tenacity Herbicide will not kill poison oak. Please see Bonide Poison Oak and Ivy Killer, which is designed just for poison oak and ivy.
