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.
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 Herbicide is best applied 2 weeks before planting/seeding a lawn or wait at least 2-3 weeks after seeding to apply. When pre-germinating and planting in the area we would recommend waiting at least 4 weeks to apply so it is established.
Tenacity is not labeled for use around anything edible so we cannot recommend it be used in an orchard. We apologize but we do not currently have a product labeled for control of nimblewill in orchards. However, you can click here and contact your local cooperative extension office to speak with a Master Gardner to find the name of a product and then contact us to see if we have access to that product.
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.
Tenacity Herbicide can be used as both a spot treatment in your lawn or as a broadcast spray. It can be applied with any hand pump sprayer. Many of our customers like the Chapin Premier 1-Gallon Sprayer.
We see no reason why you cannot apply Weed Be Gone now. It has been 3 weeks after Tenacity Herbicide, which is plenty of time. Please take a look at the Tenacity product label to be sure that it is safe to apply to your particular grass species.
No, Tenacity Herbicide is not labeled for Horse's Tail (Equisetum arvense), so we would not recommend using this product for it.
It may be fine to mix both Tenacity and Gordon's Trimec together but has not been tested by the manufacturer. We recommend that you perform a jar test to an inconspicuous area first prior to a full application to confirm if you wish to use them both together.
Tenacity Herbicide has been tested on both ine fescue (creeping red, chewings and hard) and tall fescue and found to be safe under trial conditions.
There is no wait time after applying Tenacity Herbicide to re-seed unless you are re-seeding with fine fescue. For fine fescue, it is recommended that you wait at least 30 days after application to re-seed.
Tenacity Herbicide will damage poa annua turfgrass. Be sure to check your grass type to ensure that the product can be used on your lawn safely.
There are no restrictions on the label for Tenacity Herbicide regarding timing around application of beneficial nematodes. Unfortuunately, not too much is known about the possible effects of using herbicides when applying beneficial insects. We would not recommend mixing or applying Tenacity immediately after appying the nematodes. We recommend contacting the manufacturer of the nematodes you are using for their recommendation on how long to wait between these applications and which is best done first.
Tenacity Herbicide is only labeled to suppress Poa Annua as pre-emergent. Tenacity Herbicide DOES NOT have any post emergent control when the poa is actively growing.
You should cover plants that you do not wish drift of a Tenacity Herbicide application to contact. It should only be applied to established listed lawns as directed. You should avoid vegetables, flowers, groundcovers (junipers), trees etc. Apply on a non-windy day.
