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 support@domyown.com 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.
Tenacity Herbicide is only safe to use on Kentucky Bluegrass, Centipedegrass, Buffalograss, Tall Fescue, Perennial Ryegrass, Fine Fescue, St. Augustine Grass (grown for sod only). Applications to other turfgrasses may result in injury or killing the desired turfgrass.
Please view the product label for more information.
Tenacity Herbicide is labeled for post emergent control of actively growing lawn burweed (spurweed, stickerweed, sandbur, sanbur, and sandspur) but will not offer any pre emergent control to prevent sandbur from germinating. When using Tenacity for post emergent control of weeds, a Non Ionic Surfactant is needed.
View the full list of Weeds Controlled (Pre & Post Emergent) on page 9 of the product label.
No, Tenacity is not labeled to treat black medic or quackgrass per the product label. The common recommendation is to kill the quackgrass with a glyphosate product like Roundup QuikPRO and then reseed after 2 weeks.
For Black Medic, if you have cool season turf then we would recommend Hi-Yield Triclopyr Ester, if you have a warm season grass then we would recommend a product such as Surge Broadleaf Herbicide.
Please be sure to review the product labels for your turfgrass and mix rates.
Tenacity Herbicide is only labeled as a post emergent for nutsedge and does not offer any pre emergent qualities for yellow nutsedge. Also, Tenacity can only be safely applied when bermudagrass is fully dormant in late fall and winter and should not be applied in spring or summer to bermudagrass. Unfortunately, there is not a pre emergent labeled for nutsedge and is best controlled using a post emergent when it is first emerging to get control of it.
Dismiss Turf is labeled for yellow and purple nutsedge, kyllinga and many other harder to kill weeds in bermudagrass at the rate of 0.18 - 0.275 fl oz per 1000 sq ft. Please view the full product label for more information.
The product label advises on waiting 7 days after applying Tenacity Herbicide if you will be applying an organophosphate or carbamate insecticide as it could cause potential injury to the turf. Other insecticides not in either of those classes would be fine to apply 24 hours after the application of Tenacity.
For example, Bayer's Dylox 6.2 Granules or Dylox 420 SL both have an active ingredient of Trichlorfon which is considered an organophosphate, therefore you should wait the window of at least 7 days before you apply Dylox 6.2 or Dylox 420 SL to the area that has been treated with Tenacity Herbicide. Other examples of organophosphate or carbamate insectides contain Malathion, Parathion, Diazinon, Fenthion, Dichlorvos, Chlorpyrifos, & Ethion.
Unfortunately, we do not carry a product that will help control crabgrass and broadleaf weeds such as creeping charlie (aka ground ivy) without also injuring the desired clover. We would only recommend spot treating the weeds with a non-selective like Roundup QuickPro and then reseeding after 2 weeks.
You can also check with your local department of agriculture or county extension office for a product you can use that could be selective.
Tenacity Herbicide is applied at 1 tsp of product + 3 tsp Non Ionic Surfactant in 2 gallons of water with using 1 gal of mixed solution per 1000 sq ft of area.
* A Non Ionic Surfactant is required for post emergent applications for the listed weeds controlled. If applying Tenacity for pre emergent control of listed weeds, a Non Ionic Surfactant is not required.
Please view the full list of weeds controlled either as a pre or post emergent on page 9 of the product label.
