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.
To control nimblewill, you should start applying Tenacity Herbicide in the spring (late-April). You will need to make two or three applications to get complete control. You can also apply Tenacity in late summer and fall, but you should initiate treatments by August for best results.
If you are spot treating, you will need to use 1 tsp. of Tenacity along with 3 tsp. Non Ionic Surfactant in 2 gallons of water per 1,000 sq. ft. Otherwise apply Tenacity at 5 fl. oz. per acre in at least 30 gallons of water per acre.

Tenacity Herbicide is best applied right at the time of seeding or close to for best results. It can be applied later if needed for the turfgrasses listed on the label with the following precaution: Avoid spraying on newly germinated turfgrass plants. Wait until the newly germinated turf has been mowed two times or four weeks after emergence (whichever is longer) before making a postemergence application.
Tenacity has been tested in tank mixtures with Barricade 65WG Herbicide (prodiamine) so yes, it would be okay to use. You would use the labeled rates for the Prodiamine, which when mixed correctly should not clog a tank sprayer.
When using Tenacity, 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 may be required depending on what weeds you are treating.
Yes, you can see some whitening of new grass after applying Tenacity. Unless renovating and/or re-seeding the home lawn, avoid broadcast applications of Tenacity for pre and post-emergence weed control because undesirable whitening of some turf grasses may occur.
If you are applying Tenacity as a pre-emergent herbicide at all, then you would want to do any work that would disrupt the soil (such as aeration) before putting down your pre-emergent. For post-emergent control, we recommend waiting a minimum of 2 days – but ideally at least a week – after applying the herbicide before aerating. You can apply Tenacity before or at the same time that you put down seed; just do not apply Tenacity to the new seedlings until the new turf is established.
Tenacity Herbicide would be best applied in temperatures below 80 degrees.
Yes, you can fertilize at the time (first application) when using Tenacity Herbicide. Please let us know if we can be of any further assistance.
SInce you can use Tenacity Herbicide either prior to or during seeding of certain turfgrasses you could either aerate before or after using the product and it would still work. There is nothing on the product label stating that there is a certain time to do aerating.
Tenacity Herbicide is not labeled for bahiagrass. However, you could use a product like ProSedge Herbicide. It is labeled for bahiagrass and is safe for use on various types of lawns, including St. Augustine, as long as it is not Floratam.
Once the application of Tenacity Herbicide has had time to dry it is safe for pets and children to reenter the treated area. Typically after 4-6 hours. The small amount of active left is not enough to injure a dog that may eat the rass.
If you have multiple sprayers, then the best thing for you to do is to calibrate your equipment using just water over a small area. For example, you can mark off an area that is 1000 sq ft (20 x 50 feet), fill your tank with 1-2 gallons of water, and then walk at your normal pace and see how much water you used to cover that area. It is most important that you use the correct amount of herbicide for the size area you are treating and think of the water as the carrier, rather than insisting on a specific amount of product per gallon of water. If you take this time to calibrate your sprayer once, then you will know how much water you use for the area going forward. Using a spray indicator dye is also a great tool so that you apply herbicides evenly over your yard.
You can apply Tenacity anytime before seeding up to the same time that you seed. If you are applying Tenacity as a post-emergent herbicide, then it is usually best to do that application first and wait for the treated plants to die so you can remove any excess dead plant matter before you overseed the lawn. Tenacity will not interfere with seed germination of turfgrasses listed as tolerant on the product label.
Yes, Tenacity Herbicide is labeled for use on Buffalograss.
Tenacity Herbicide cannot be applied around edible vegetation. When applying the product to your lawn, you would want to be sure to avoid over-spray or drift of spray applications onto the fruit trees, and avoid spraying within the drip line of any edible trees.
