Tenacity Herbicide is best applied right at the time of seeding or close to for best results. It can be applied later if needed for the turfgrasses listed on the label with the following precaution: Avoid spraying on newly germinated turfgrass plants. Wait until the newly germinated turf has been mowed two times or four weeks after emergence (whichever is longer) before making a postemergence application.
After using Tenacity Herbicide you can triple rinse the sprayer or use a spray tank cleaner to ensure no residual is left.
If you have multiple sprayers, then the best thing for you to do is to calibrate your equipment using just water over a small area. For example, you can mark off an area that is 1000 sq ft (20 x 50 feet), fill your tank with 1-2 gallons of water, and then walk at your normal pace and see how much water you used to cover that area. It is most important that you use the correct amount of herbicide for the size area you are treating and think of the water as the carrier, rather than insisting on a specific amount of product per gallon of water. If you take this time to calibrate your sprayer once, then you will know how much water you use for the area going forward. Using a spray indicator dye is also a great tool so that you apply herbicides evenly over your yard.
You can apply Tenacity anytime before seeding up to the same time that you seed. If you are applying Tenacity as a post-emergent herbicide, then it is usually best to do that application first and wait for the treated plants to die so you can remove any excess dead plant matter before you overseed the lawn. Tenacity will not interfere with seed germination of turfgrasses listed as tolerant on the product label.
Tenacity Herbicide cannot be applied around edible vegetation. When applying the product to your lawn, you would want to be sure to avoid over-spray or drift of spray applications onto the fruit trees, and avoid spraying within the drip line of any edible trees.
Since Tenacity Herbicide can be used only on fully dormant Bermudagrass, there is not a time when you would be overseeding and using Tenacity at the same time. You would overseed with Bermuda when the turf is actively growing in spring or summer, if needed at all. So if you applied Tenacity on dormant Bermuda, then it would be long gone by the time the turf is completely green and any seeding would be fone. If you would like to tell us more about the weeds you are targeting, then we can recommend alternate products for your needs.
Yes, Tenacity Herbicide is labeled for wild violets when used as directed on the label.
The Tenacity product label does state that it can be mixed with pre-emergence products to provide season long control. Dimension's product label does also state that it can be. Please refer to both for complete instructions and you may need to perform a compatibility test before treatment.
If you are trying to apply Tenacity Herbicide to control bentgrass, 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. Bentgrass control may be more effective in the late summer/early fall just prior to onset of renewed bentgrass growth, than spring/early summer applications."

Tenacity Herbicide when applied per label will not harm established Centipede. Bermuda can be sensitive to Tenacity.
The Tenacity product label suggests the product be applied with any non-ionic surfactant.
SInce you can use Tenacity Herbicide either prior to or during seeding of certain turfgrasses you could either aerate before or after using the product and it would still work. There is nothing on the product label stating that there is a certain time to do aerating.
Tenacity Herbicide is a great option for post emergent control of nimblewill. However it is not safe for use in Zoysiagrass and is only for use on St Augustine when used in sod farm. You could use the Tenacity as a spot treatment only for nimblewill as we would not recommend using it as a broadcast spray on your lawn.
No, Tenacity Herbicide is not labeled for application to bahia grass.
Yes, Tenacity Herbicide is labeled to control Pennsylvania Smartweed.
Tenacity Herbicide 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 is only labeled to be applied to dormant bermudagrass, it could harm actively growing bermuda or inhibit seeds from growing. You need to wait at least 18 months to seed the area after an application
