When using Tenacity Herbicide as a post-emergent, you can apply anytime before seeding, but keep in mind that it may take a couple weeks to kill the target plants, so you would want to wait for those plants to die before aerating and reseeding. It is recommended to rake out the dead plant matter prior to aerating and reseeding the lawn.
Tenacity Herbicide will kill the crabgrass, weeds, and clover eventually. However, if you are seeding you may want to remove the dead weeds to allow the seeds more room to grow. Otherwise, you can just leave it as is.
Tenacity Herbicide is not specifically labeled for Epipactis or Helleborine. There is an article here helps explains how to eliminate it.
Tenacity Herbicide can be applied 30 days apart. Three are the most applications that are recommended depending on the weed you are treating for.
Tenacity Herbicide does not list creeping beliflower on the label as tolerant or a weed controlled. We would suggest contacting the manufacturer Syngenta at 336-632-6000 for more information.
Tenacity Herbicide is only labeled to be used on Bermuda when it is fully dormant, otherwise it can be sensitive to applications and could harm it. It is not recommended for elimination of Bermuda or desired Bermuda turf.
Many wildflowers are considered weeds and Tenacity Herbicide could prevent them from growing or can cause damage to the seeds that do sprout. If you have weeds in the area, we recommend using a roundup type product to kill all of the weeds and you can plant the seeds after two weeks.
We would recommend removing the dead bentgrass before planting your seed after using Tenacity Herbicide.
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.)
Once the application of Tenacity Herbicide has had time to dry it is safe for pets and children to reenter the treated area. Typically after 4-6 hours. The small amount of active left is not enough to injure a dog that may eat the rass.
If the Tenacity Herbicide application had enough time to completely dry before the temperatures spiked to 93 degrres, there shouldn’t be any issues. It is recommended to apply Tenacity when temperatures are between 65 to 85 degrees so early morning or late evening applications may work best if temperatures above 85 degrees during the day are expected. If any yellowing or discoloration occurs, the turf should recover after a couple weeks.
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.
Tenacity Herbicide can last in the soil up to 30 days if used as a broadcast pre emergent treatment, so you would need to wait at least 30 days after an application before putting in any new seeds.
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).
We recommend that you let the Tenacity Herbicide application dry completely and then applying the insecticide.
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.
