No, Tenacity Herbicide is not labeled for use on Zoysia and could potentially cause damage or injure the lawn. Unfortuanately, there is not a pre emergent currently on the market for creeping charlie and nutsege therefore the best method of control will be to use a post emergent when the weeds are actively growing. Dimension 2EW is a great choice for pre-emergent control for over 200 broadleaf and grassy weeds.
Blindside Herbicide is a post emergent labeled to contol activily growing weeds such as creeping charlie (ground ivy) purple and yellow nutsege, crabgrass, dandelion, etc. The mix rate for Zoysia is 0.15 - 0.23 oz per 1000 sq ft (6.5 - 10 oz / per acre) .
The rate for Tenacity Herbicide is 4 fl to 8 fl oz / acre depending on the type of turfgrass you have. Please refer to the chart on page 8 of the produt label for your turfgrass and the recommended rate.
Spot Applications of Tenacity are applied at 1 tsp Tenacity + 3 tsp Non Ionic Surfactant per 2 gallons of water (apply at 1 gallon per 1000 sq. ft.)
Tenacity is not labeled for Bindweed Vine/Morning Glory. Glyphosate looks like the best option to use.
When applying Tenacity Herbicide for pre emergent contol of the listed weeds, temperatures should be around 55 – 65 degrees consecutively for 4-5 days. For Kentucky Bluegrass and Tall Fescue, Tenacity is able to be applied before, at the same time or directly after seeding and will not inhibit grass seeds from germinating.
Also, refer to the Weeds Controlled Chart on page 9 of the product label for the specific weeds you are targeting to see if they are marked as Supppressed, Controlled or Both when using Tenacity. It is possible that the weeds you are targeting are not suppressed with pre emergent applications and only controlled as a post emergent.
If applying as a post emergent with a Non Ionic Surfactant when weeds are actively growing, you would need to wait at least four weeks or until the new grass has been mowed twice, whichever is longer.
The key time to avoid spraying Tenacity on new seedings, either as a pre-emergent or a post-emergent, would be when the new seedlings have started to come up but are not yet established. Please refer to page 12 of the label for complete application instructions around seeding.
There may not be any options for reviving the turf that was damaged by Tenacity Herbicide. You can apply a lot of water to the treated areas but you may need to reseed or resod the injured areas eventually that died out from the application (this can take weeks depending on the date of application).
Battleship III is only for controlling broadleaf weeds and will not effect crabgrass or other grassy weeds at all. The label does not mention tank mixing with herbicides like Tenacity only fertilizers so we would not recommend doing so.
Unfortunately Tenacity Herbicide is only sold in the 8 oz size and is not labeled to be used on pastures at all so not recommended.
Tenacity Herbicide is not listed to control any type of vines not can it be used over juniper. We would recommend carefully treating using a non selective such as Roundup directly to the vine. This is best done if the vine is cut and applied directly using a small paint brush to the fresh cut surface. Or hand pulling is the other option.
Tenacity Herbicide is not labeled to kill Blue Star Creeper but could injure groundcovers if contacted, it would not be recommended to be used to control it though.
Tenacity Herbicide is not labeled for use on edible vegetation, and we would not recommend eating any fruits or vegetables from plants that have been contacted by the product for at least the growing season. You can also contact the manufacturer Syngenta for further clarification and product support by calling 1-800-334-9481, or by visiting their website's contact page here.
Yes you can overseed 2-3 weeks after application of Tenacity Herbicide. You will want to wait until the target plants have died, so you can rake out the dead plant matter. You then can overseed anytime thereafter.
Tenacity Herbicide is not labeled for use on St Augustine home lawns, it is only labeled to be used on St Augustine grown for sod aka commercially grown. Unfortunately, the only way to reduce the effects of an herbicide would be to use an activated charcoal immediately after applying (within hours).

Tenacity Herbicide should be used with a Non Ionic Surfactant and per the product label, better results are achieved in late summer early fall applications just prior to onset on renewed bentgrass growth than spring/summer applications.
Tenacity Herbicide is labeled safe for fescue lawns however can ONLY be applied to bermuda turfgrass when it is dormant without the risk of injury. Tenacity can be used for pre and post emergent (with Non Ionic Surfactant) control of clover but will only suppress poa annua, it will not fully control it.
Since poa annua and cool season grasses are so closely related, there are few products that will kill the poa annua without also harming the lawn. For Poa Annua in cool season turfgrasses, we recommend a spot-treat with a Roundup-type product and then reseed with the desirable grass type in those areas.
Applying a pre emergent like Pendulum 2G or Dimension 2EW in late fall and early spring to prevent weeds like poa annua, clover, crabgrass, and many other grassy and broadleaf weeds from germinating is also helpful.
Please view our Lawn Care Schedule Calendar for more information.
Tenacity should be mixed with a Non Ionic Surfactant for post emergent applications to actively growing weeds. Mowing should be delayed 2 days before or 2 days after the application for best results.
For treatments around the Elm Tree, the product label states to avoid applications over the top of exposed roots of trees and ornamentals. It is best to keep herbicide applications outside the dripline of the trees if possible but if necessary, carefully spot treat the weeds themselves and do not broadcast under the canopy.
Please review the full product label for more information and complete application instructions.
We would need to know more information to better assist you regarding your application. Can you please contact us at 1-866-581-7378 or [email protected] with the following information:
What mix rate did you use of each, the Tennacity, Turf Mark Blue and Non Ionic Surfactant and in how much water?
What model sprayer and spray nozzle were you using?
When did you purchase these and where were the products stored before use?
Did the mix solution sit for any amount of time or used within 24 hours?
There should be no issues applying Tenacity around the same time as a fertilizer as long the label on the fertilizer does not state that it cannot be used with herbicides.
As stated on the product label of Tenacity, this product should be applied when there is no rain in the forecast for at least 48 hours. "If rainfall (0.15 inches) has not occurred within 10 days after preemergence application, activate with 0.15 inches of irrigation." This product can be applied to established, tolerable turf types.
Please be sure to review the product label for more information and complete application instructions.
