According to the Tenacity product label for smaller applications, you will need to mix 1 tsp of Tenacity and 3 tsp of surfactant to 2 gallon of water, using 1 gallon each to cover 1,000 sq ft. Be sure to check the product label to ensure proper rates for your turf type and target weeds are being used to get the best results.
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.
Tenacity Herbicide would be best applied in temperatures below 80 degrees.
Tenacity Herbicide would not be the best product for Poison Ivy. BK 32 would be a better option for Bittersweet and Poison IVy. BK32 can be applied to most Residential Turf: Bluegrass, Fesue, Rye, Bent, Bermuda, Bahia and Zoysia Lawns
Avoid application to St. Augustine or Centipede lawns unless injury can be tolerated.
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.
Tenacity Herbicide can be used at the time of seeding for most grass types. Fine fescue is the only grass seed that should not be used at the time of application. It is recommended that you wait 2-4 weeks after an application of Tenacity Herbicide to reseed with fine fescue.
No, the bleached seeds that were treated with Tenacity are no longer viable. It may require more than one application for this.
Tenacity Herbicide and QuinKill Max have different active ingredients and different modes of action. QuinKill contains quinclorac, which is a post-emergent herbicide targeting primarily grassy weeds like crabgrass. Tenacity can be a pre-emergent or a post-emergent, depending on the application and the target weeds. There is a complete list of action on the product label. If you are overseeding with fescue, then you can apply Tenacity at or as close to seeding as possible, except for fine fescue seedings. Avoid applications to newly emerged seedlings until established (4 weeks or after the second mowing, whichever is longer). Please refer to the product label for complete application instructions.
Tenacity Herbicide should be used or discarded within 24 hours once it has been mixed with water.
Yes, Tenacity Herbicide and Triplet can be mixed together. Be sure to do a small tank mixture to ensure there is no clumping in the tank.
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.
If you are planning to add any type of groundcover like mulch or pine straw, it is always best to put down your pre-emergent and water it in before applying the groundcover. In this situation, however, we would not recommend using Tenacity Herbicide next to or under desirable trees or ornamental plants. Per the product label, " Avoid over-spray or drift of spray applications onto ornamentals or flower beds and gardens. Roses and daylilies are sensitive plant species. Avoid applications over the top of exposed roots of trees and ornamentals." Our most popular pre-emergent herbicide for use around established ornamental plants is Snapshot.
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.
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.
It is recommended that you do not mow 2 days before or 2 days after the application of Tenacity Herbicide.
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 should be applied when temperatures are between 65-85 degrees. We suggest making an early morning or late evening application if temperatures in your area exceed 85 degrees during the day.
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.
Post-emergent herbicides like Tenacity Herbicide work best when the plant is young and actively growing. Since that is what you are currently seeing, now would be a good time for the first application.
