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.
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.
As long as the initial application of Tenacity Herbicide has had a chance to dry after a post emergent application it will not be washed away with rain after. Best to apply when no rain is expected within 24 hours to be sure.
Tenacity Herbicide, as well as any other herbicide, should not be applied to a lawn that is stressed due to drought conditions as you risk further damage being done to the lawn.
Tenacity Herbicide should be applied at least 15 ft away from any edible vegetation.
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.
Tenacity Herbicide is not labeled for trees so spraying around the trees could possibly harm them. It states on the product label: Avoid applications over the top of exposed roots of trees and ornamentals. Just about all herbicides are going to have the restriction that applications should be kept out of the dripline of desirable trees. The best you could do is carefully spot treat the weeds themselves and not broadcast in these areas.
Tenacity Herbicide can be used as a spot treatment for existing broadleaf weeds once the new lawn is established and has been mowed at least 2-3 times.
Tenacity is not labeled to treat corn speedwell. We would recommend Speedzone EW. Please refer to the label for tolerant turf types and complete application instructions.
No, Tenacity Herbicide is not labeled for application to carpetgrass. It is only labeled for use in Kentucky Bluegrass, Centipedegrass, Buffalograss, Tall Fescue, Perennial Ryegrass, Fine Fescue, St. Augustine Grass (grown for sod only)
Tenacity Herbicide is not labeled for use on pasture land, and a 90 day waiting period is required after an application until it is safe to allow animals to graze on treated areas.
We are not aware of a selective herbicide labeled to treat blue star creeper. You could potentially use a non selective product such as RoundUP Quikpro and reseed/resod in those areas.
Yes, Tenacity Herbicide can be shipped to Washington state.
Tenacity that has been mixed with water and a surfactant should be used within 24 hours of mixing and then discarded. If it is in its original container and stored away from extreme temperatures, it will have a three year shelf life unmixed.
Tenacity Herbicide does not have any insecticidal properties to it there for would not ham any beneficial insects.
Tenacity Herbicide is not labeled safe for use on Floratam species and is only for use on St Augustine grown for sod.
Tenacity is safe for use on Bermudagrass only if the Bermuda is completely dormant. It cannot be applied to grass that is already growing.
Tenacity Herbicide can be used on a lawn that 2,4 d or other herbicides have been applied to safely as long as you follow label instructions and apply it evenly. Tenacity will only last about 30 days as a pre emergent compared to other pre emergents on the market that will last 3-4 months. Tenacity is mostly used as a pre emergent in the spring or fall when customers are over seeding their lawns with a cool season grass to fill in bare spots, as its one of the only products that can be used at this time without harming the seed. If you are not seeding, you may want to consider a longer lasting pre emergent or one that covers a wider range of weeds than the Tenacity does, like the Dimension 2EW or Pendulum 2G for instance. If using Tenacity as a pre for crabgrass, you want to put it down at or just prior to your soil temperatures reaching 55 degrees in order to be effective. If soil temps have already progressed past 55 degrees your pre emergent will not do much to stop the weeds.
Tenacity Herbicide should be appllied after you have leveled your yard so the barrier is not disturbed or covered with other soil where seeds would not be effected by it.
Tenacity Herbicide is not labeled to control or kill ajuga. We currently do not have any products that are labeled to eradicate Ajuga/Bugleweed, you may have to spot treat with something like Roundup QuikPro in the areas that have the weed and then reseed the areas in 2 weeks
