Tenacity is not labeled to be used on bahiagrass. The most effective product to control Nimblewill pre-emergently has been removed from the market (MSMA). We have had a lot of folks report that Dimension does a pretty good job pre-emergently but since the product is not technically labeled for Nimblewill we cannot legally recommend it for this use. The usual recommendation since the ban of MSMA is to use a non-selective product such as Round Up on the weed, wait 14 days and re-seed or sod the area.
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.
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.
Tenacity Herbicide is not labeled for post emergent control of burweed.
Tenacity Herbicide is only safe to use on dormant Bermudagrass, and it will not offer post-emergent control of poa annua, per the product label. A better choice to control existing poa annua in bermudagrass would be Monument 75WG Herbicide. Be sure to use a non-ionic surfactant with Monument as well. We also recommend using a pre-emergent herbicide such as Dimension 2EW or Prodiamine 65 WDG in late Summer/early Fall for the best control of annual bluegrass. Please see our Poa Annua Lawn Care Guide for more tips and information.
Avoid applications of Tenacity? over the top of exposed roots of trees and ornamentals. Please refer to the product label for full detailed usage instructions.
Tenacity Herbicide is not labeled to treat poa trivialis. Please provide your desired turfgrass for an alternate recommendation. Thank you!
Per the manufacturer, Tenacity Herbicide can be used in a hydroseeding tank as long as you're able to apply at a rate of 5 oz per Acre.Water is just the carrier but you need to make sure you irrigate the herbicide well. If this isn't a possibility then we would recommend making separate applications, hydroseeding first and then applying Tenacity.

Yes, you can apply Tenacity just before or at the time of seeding for best results. Be sure that you are not using Tenacity at the same time as seeding if the grass is more than 20% hard or fine fescue.
Tenacity Herbicide is labeled to suppress poa annua when used as a pre-emergent. Please provide your desired turf grass for seeding details. Thank you!
Tenacity Herbicide is labeled to be safely applied to fine fescue and is not labeled to kill it so we cannot recommend it for that use. When you are trying to remove another cool season turf type from KGB the best option is to use a product like Roundup Quikpro (or non selective/glyphosate) and then re-seed with your KBG.
There is not a set flow rate for applying the Tenacity Herbicide. You just need to apply at the rates on the label for your turfgrass and application type.
Tenacity Herbicide is a herbicide only and will not work as a fungicide. Clearys 3336F is a great product to use for brown patch as directed on the product label.
Tenacity is only going to suppress poa annua when used as a pre-emergent for it. You would really only use Tenacity as a pre-emergent over the entire lawn if you are needing a pre-emergent to use at the same time as seeding or over-seeding. Otherwise, ProGrass would be a better choice for poa annua control and for use on established perennial ryegrass.
No Tenacity is not labeled for Hippuris Vulgaris (Mares tail). Crossbow Herbicide is labeled for marestail. Please refer to the product label for complete application instructions.
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. If you are able to spot treat with RoundUp QuikPro, that is another option. It would still be ideal to wait at least 10-14 days after applying the Roundup QuikPro before raking out the dead plants and re-seeding those areas.
Tenacity Herbicide is safe to be used only on dormant Bermuda lawns. Please refer to the product label for application instructions and mix rates.
