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 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 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 does not have any insecticidal properties to it there for would not ham any beneficial insects.
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.
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.
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 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.
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 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 should be applied at least 15 ft away from any edible vegetation.
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.
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.)
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.
