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.
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.
Your first application of Tenacity Herbicide in the fall to control bentgrass will be most effective just before the onset of new growth. You can then apply at 2-3 week intervals. You do not want to wait for it to be fully re-established to start treatment.
Tenacity Herbicide is not labeled to treat poa trivialis. Please provide your desired turfgrass for an alternate recommendation. Thank you!
Yes, you can apply Tenacity just before or at the time of seeding for best results. Be sure that you are not using Tenacity at the same time as seeding if the grass is more than 20% hard or fine fescue.
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.
If it takes one gallon of water to cover 1,000 sq ft then use one gallon of water to the appropriate amount of products. If it takes 2 gallons of water, you will still use the same amount of Tenacity and surfactant. The water is the carrier so that amount of product is applied over the full 1,000 sq ft.

Tenacity Herbicide may cause temporary whitening of turfgrass foliage. In general, symptoms appear five to seven days after application and last for several weeks. A repeat application to the same site causes less whitening of the plant tissue.
Tenacity Herbicide is not labeled to control Poa Annua/Annual Bluegrass as a post-emergent application. The label only states that it could cause injury to it if sprayed. It is only labeled to be used to suppress poa annua when used as a pre-emergent. Please provide your desired turf grass for an alternate recommendation. Thank you!
It is not recommended to mix certain insecticides, herbicides, or fungicides with Tenacity Herbicide. You should wait to apply insecticides 7 days after treating with Tenacity Herbicide to avoid potential turf injury. Other ingredients in the fungicides or herbicides would be fine to use at the same time if there are no resttrictions on the product label.
Tenacity Herbicide would be a great option for you to control crabgrass, and yes it is advised to use a dye like Turf Mark Blue with it so you can make sure to not overlap if you plan to do a broadcast application on the property.
Tenacity Herbicide can be used for both nimblewill and wild violet. To control nimblewill, you should start applying Tenacity Herbicide in the spring (late-April). You may 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. For other weeds such as wild violet apply to young, actively growing weeds.
Tenacity Herbicide may be applied when soil temperatures are around 55 degrees or higher. Do not apply when air temperature exceeds 85 degrees.
Tenacity Herbicide is labeled to suppress poa annua when used as a pre-emergent. Please provide your desired turf grass for seeding details. Thank you!
For best results, do not apply Tenacity Herbicide when rainfall is forecasted to occur within 48 hours.
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.
Wiregrass is a form of bermudagrass. The product label states that bermuda grass is sensitive to Tenacity but it would not be recommended as a product specifically used to kill it. Fusilade II can be used to get rid of bermuda grass in tall fescue. Please be advised that bermuda grass is extremely difficult to control and you will likely need to make several applications.
