If it rained less than 4 hours after applying Tenacity Herbicide, you will need to reapply, but wait until the area has dried. Tenacity Herbicide is labeled for Yellow Nutsedge so it should work if that's what you have, just make sure to follow the label instructions. Sedgehammer Herbicide is definitely a great solution for nutsedge. According to the label you may overseed with annual or perennial ryegrass or bermudagrass, 2 weeks after application. All other seeding can be done 4 weeks after application. If you plan to aerate, you can do it 3-4 weeks after application as well to avoid stressing your grass.
Tenacity Herbicide should be used when the temperatures are above freezing on a daily basis. Your target temperature range will depend on whether you are using Tenacity for pre-emergent or post-emergent applications.
Tenacity Herbicide is our most popular product for eliminating bentgrass from other desirable turfgrasses, but it does typically require multiple applications. Late summer/Fall applications will be more effective than Spring applications.
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 not labeled for post emergent control of burweed.
While Tenacity is labeled to be used on Buffalograss it is not labeled to control wheatgrass. We are not able to find anything that is labeled to do so. The best thing to do for this issue is to spot treat with a glyphosate based product like GlyPhoSel Pro and reseed/sod the treated area.
Tenacity is not labeled for quackgrass elimination. We do carry a similar product called Certainty that is a selective, post-emergent that is labeled to eradicate quackgrass. Please refer to the product label for full mixing and application for the best results.
Tenacity Herbicide if stored in a cool dry area will last up to 3 years. It sounds like you need to purchase fresh product. The mix rate you are using is correct.
No, Tenacity Herbicide is not organic.
Yes, you can use Tenacity to kill nimblewill. 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.
You would not apply Tenacity Herbicide at a rate of more than 16 oz per acre per year or per crop (equivalent to a maximum of 0.50 lb. of mesotrione per acre per year), whichever is shorter.
We would recommend waiting at least four weeks to apply a Weed and Feed after using Tenacity Herbicide.
After further information from the manufacturer they have verified that to making a pre-remergent application with Tenacity you will need to apply a post emergent application once you detect germination of the weed itself. Syngenta recommends to apply no more than 3 application per year.
Tenacity Herbicide is labeled to be applied and safe for Perennial Ryegrass.
Yes, Tenacity Herbicide can be used at the time of seeding when using Jonathon Green Black Beauty Ultra.
It is possible that Tenacity Herbicide will harm daffodils if sprayed. Since flowers can be considered a broadleaf weed, this product can harm it. Tenacity Herbicide is only labeled for use on listed lawns.
Tenacity Herbicide can take multiple applications to be most effective. It does not require irrigation after application for post-emergent weed control. Are you mixing a surfactant like Non Ionic Surfactant? This helps the product to stick and penetrate to the xylem of the plant best. Be sure the target weeds are listed on the Tenacity product label.
According to the Tenacity product label you can apply prior to seeding or post seeding of tolerant turfgrass species listed on the label, except fine fescue. If you are applying Tenacity after seeding, you should wait at least four weeks or two mowings, whichever is longer, before applying Tenacity.
Quackgrass is not on the label to be controlled by the Tenacity, and we cannot recommend you use it for your needs with it not being listed. We do however carry Certainty, which is a selective post emergent herbicide like Tenacity, and does have Quackgrass listed on the label for weeds controlled. You can see the dilutions and what grasses Certainty is safe to be used on, on the product label.
