As advertised, Tenacity Herbicide is an incredibly effective weed killer and provides both pre-and post-emergent control for over 46 broadleaf grass and weed species.
Tenacity works primarily from the active ingredient mesotrione. Mesotrione is derived from a naturally occurring compound produced by Callistemon citrinus, otherwise known as the bottlebrush plant.
In a nutshell, the mesotrione works by inhibiting photosynthesis in certain plant species. This prevents plants from creating enough food, so they are unable to grow or maintain their biomass. This is distinct from other types of herbicides that may only kill certain sections of plants they come into direct contact with.
By contrast, Tenacity is a systemic herbicide. Upon being absorbed by the target plant, the herbicide moves throughout the plant entirely. This kills the target plant completely, making it extremely effective as a long-term herbicide solution.
For instance, this means that any target plants won’t have the roots survive to grow again next season. This permanent eradication is effective, but it can also be a little dangerous if misapplied.
Using Tenacity weed killer is pretty and easy, which is another reason why it’s so popular with homeowners with big lawns they need to take care of.
- To start, you apply Tenacity by mixing it with 30 gallons of water per acre at concentrations of 2 to 4 fluid ounces per acre
- You only increase this concentration to 5 to 8 fluid ounces per acre if applying Tenacity to new seedings
- Reapply your Tenacity every 2 to 3 weeks based on weed growth progress
You may also consider using Tenacity before you see weeds crop up. Since Tenacity can be used as a pre-emergent herbicide agent, you can potentially prevent weeds from impacting your lawn if you regularly use this herbicide every month or so.
It's important to reapply Tenacity weed killer every two to three weeks. You can reapply Tenacity multiple times if you don't get the desired results right away. However, it's important to remember that you shouldn't apply more than 16 ounces of tenacity per acre per year.
1. Tenacity is Selective
One of the biggest benefits of using Tenacity as a weed killer is that it's selective. That means it won’t accidentally destroy your lawn, even if you apply it throughout your grass. So you can easily use Tenacity on both newly seeded turf and already established turf depending on your preferences.
2. Fast Results
Furthermore, Tenacity produces results relatively quickly compared to other herbicides. As soon as your target plants absorb Tenacity, it’ll quickly travel throughout and suppress their growth. In general, it only takes between two and three weeks for weeds to die after applying Tenacity.
3. Easy to Mix With Other Herbicides
Another benefit of using Tenacity weed killer is that you can mix it with other herbicides in tanks. For instance, you can easily combine Tenacity with:
- And more
By mixing all of these into a single tank, it’s easy to quickly and efficiently spray even large sections of turf with a wide variety of weed killers and weed controllers. This, in turn, allows you to complete your lawn care chores that much more quickly. You can protect your lawn from multiple weed species at once by mixing herbicides.
Tenacity Herbicide is a “selective” herbicide agent. This means that it’s incredibly effective if you only want to kill a few certain weeds or plant species that may be mixed in with your regular lawn grass. It does not kill all types of grass that comes into contact with, so it’s relatively safe provided you use it correctly.
As a pre-and post-emergent herbicide, Tenacity allows you to destroy weeds before they even emerge from your lawn’s soil and after they have already appeared. Thus, it’s good both as a preventative measure to stop weeds from spreading in the first place and is a good solution if you find weeds already spreading throughout your yard.
Tenacity is extremely effective at killing crabgrass and other weeds. Here is a list of the weeds Tenacity can kill:
- yellow foxtail
- yellow nutsedge
- ground ivy
- and more
