You can apply Tenacity herbicide on the day of seeding. Once you have seeded you will need to wait until the grass is mature. You can start applying a month before seeding so you can apply 2-3 applications before seeding.
Tenacity Herbicide is labeled for post-emergent control of Nimbleweed to established cool season turf. Per the product label, you may need a second application after 2 to 3 weeks. Apply to young, actively growing weeds, and be sure to use a surfactant such as Southern Ag Non-Ionic surfactant for post-emergent applications.
Tenacity Herbicide is labeled to control bentgrass but it does need to be applied when it is actively growing and healthy. Per the product label: Apply Tenacity at 5 fl. oz. per acre in at least 30 gallons of water per acre at two to three week interval for up to three applications. Apply with a NIS surfactant. Bentgrass control may be more effective in the late summer/early fall just prior to onset of renewed bentgrass growth, than spring/early summer applications
Tenacity Herbicide will suppress Bentgrass after a few applications but is not labeled to suppress bermuda. Please follow the product label for application. Be sure to apply during cooler times of the day to avoid harming your desired turf grass.
Per the manufacturer, Tenacity Herbicide can be used in a hydroseeding tank as long as you're able to apply at a rate of 5 oz per Acre.Water is just the carrier but you need to make sure you irrigate the herbicide well. If this isn't a possibility then we would recommend making separate applications, hydroseeding first and then applying Tenacity.
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.
Tenacity Herbicide is not labeled for sandspur. We suggest Pastora Herbicide instead. It is labeled to control sandbur aka sandspur when used as directed on the product label for post or pre emergent control
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.
Per the manufacturer, " Tenacity has been tested in tank mixtures with Barricade 65WG Herbicide (prodiamine), Vanquish® (dicamba), Turflon® ester (triclopyr), Spotlight™ (fluroxypyr), Quicksilver™ (carfentrazone), Basagran® (bentazon), Princep® (simazine), and AAtrex® (atrazine) for safety and efficacy on turfgrasses. Tenacity must be applied at reduced rates (4 fl. oz./A or less) if tank mixed with atrazine, bentazon or simazine. Other tank mixture partners may be safe but have not been tested. Turf managers wanting to tank mix Tenacity with other herbicides should test on a small basis for compatibility, safety and efficacy before treating large areas. See product labels for directions and precautions."
Tenacity Herbicide should be used within 24 hours of mixing with water.
Tenacity Herbicide should not be used around or on desirable ornamentals and/or trees or used within 3 feet of trees or ornamentals. Unfortunately, there is not a product that can be used to reverse the effects of the Tenacity sprayed on intolerant plants.
There are no time restrictions when applying Tenacity Herbicide along with insecticides or fertilizers. You can either spot treat or broadcast depending on how much of the target weed you are dealing with.
Tenacity Herbicide would only need a surfactant when using as a post emergent. For pre-emergence control you need to water the product in and apply before the weeds have germinated/emerged so it appears to be too late to benefit from that.
You should cover plants that you do not wish drift of a Tenacity Herbicide application to contact. It should only be applied to established listed lawns as directed. You should avoid vegetables, flowers, groundcovers (junipers), trees etc. Apply on a non-windy day.
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 is required after two to three weeks for improved postemergence weed control.

Yes, Tenacity Herbicide is labeled for wild violets. The rate for 1000 square feet is 1 teaspoon.
Tenacity will help control annual bluegrass (poa annua) from germinating in the Fall, but it will not interfere with new plantings of Kentucky Bluegrass. If you are putting down any new seed, apply Tenacity as close to seeding as possible. If you have new KBG seedlings coming up already, then wait to apply Tenacity until after the new grass is established (2 mowings or four weeks, whichever is longer).
It is not recommended to mix certain insecticides with Tenacity Herbicide. You should wait to apply organophosphate or carbamate insecticides 7 days after treating with Tenacity Herbicide to avoid potential turf injury. Other active ingredients would be fine to use at the same time.
