Crabgrass is a common lawn weed that can quickly spread and take over your lawn if left untreated. While there are many herbicides available on the market that are designed to kill crabgrass, not all herbicides are created equal. One herbicide that has gained popularity in recent years for its ability to control crabgrass is Tenacity.
What is Tenacity Herbicide?
Tenacity herbicide is a selective herbicide that works by inhibiting a key enzyme needed for plant growth. It is a systemic herbicide, meaning it is absorbed by the plant and moves throughout the plant’s leaves, stems, and roots.
One of the unique features of Tenacity herbicide is that it can be used both as a pre-emergent and post-emergent herbicide for a variety of turfgrass species, including Kentucky bluegrass, tall fescue, and perennial ryegrass. It can also be used to control a wide range of broadleaf weeds and grasses, including crabgrass.
How does Tenacity Herbicide Work on Crabgrass?
Crabgrass is notoriously difficult to control, especially once it has established itself in your lawn. Tenacity herbicide works by blocking photosynthesis in the plant, causing it to turn white or bleach out. This is known as whiteout mode. Tenacity also inhibits cell division in the plant, which ultimately leads to the death of the plant.
When used as a pre-emergent herbicide, Tenacity can help prevent crabgrass from germinating in the first place. When used as a post-emergent herbicide, Tenacity can help control crabgrass that has already emerged.
How to Apply Tenacity Herbicide for Crabgrass Control
Before applying Tenacity herbicide, it is important to read and follow the label instructions carefully. The label will provide information on the correct dilution rates, application rates, and application timing for your specific turfgrass species and weed problem.
When using Tenacity as a pre-emergent herbicide for crabgrass control, it should be applied to the soil surface before the crabgrass seeds germinate. This usually occurs in the late spring or early summer when soil temperatures reach 55 degrees Fahrenheit or higher. Tenacity should be applied at a rate of 4-8 fluid ounces per acre, depending on the level of weed pressure in your lawn and the type of turfgrass you have.
When using Tenacity as a post-emergent herbicide for crabgrass control, it should be applied to actively growing crabgrass. The best time to apply Tenacity for post-emergent control is when the crabgrass is in the one- to three-leaf stage. Tenacity should be applied at a rate of 4-8 fluid ounces per acre, depending on the level of weed pressure in your lawn and the type of turfgrass you have.
Benefits of Using Tenacity Herbicide for Crabgrass Control
There are several benefits to using Tenacity herbicide for crabgrass control:
- Effective at controlling both pre and post-emergent crabgrass
- Selective herbicide that will not harm most turfgrass species when used as directed
- Can also control a wide range of broadleaf weeds and grasses
- Low toxicity to humans and pets when used as directed
- Can be used as part of an overall lawn care program for a healthy and weed-free lawn
Precautions to Take When Using Tenacity Herbicide
While Tenacity herbicide is generally safe when used as directed, there are a few precautions you should take when handling and applying the herbicide:
- Wear protective clothing, including gloves, long sleeves, and pants, when handling the herbicide
- Avoid inhaling the herbicide or getting it on your skin or in your eyes
- Keep pets and children away from treated areas until the herbicide has had a chance to dry completely
- Do not apply Tenacity herbicide to stressed turfgrass or during hot, dry weather
- Follow the label instructions carefully for application rates and timing

Yes, Tenacity Herbicide is very effective at getting rid of crabgrass. It works by inhibiting the photosynthesis process in plants, which causes them to turn white and die. Crabgrass is particularly susceptible to Tenacity Herbicide, making it an excellent choice for controlling this weed.
When should I apply Tenacity Herbicide to control crabgrass?
The best time to apply Tenacity Herbicide to control crabgrass is in the spring, once the grass has started to green up and the soil temperature has reached 55 degrees Fahrenheit. This is when crabgrass begins to germinate, so applying the herbicide at this time will prevent it from taking hold.
How do I apply Tenacity Herbicide to control crabgrass?
Tenacity Herbicide can be applied using a sprayer or a watering can. Mix the herbicide with water according to the instructions on the label, and apply it evenly to the affected areas. Be sure to avoid spraying the herbicide onto desirable plants, as it can cause damage.
Is Tenacity Herbicide safe to use around pets and children?
Tenacity Herbicide is generally safe to use around pets and children when used as directed.
