Does Tenacity Kill Bermuda Grass?


Bermuda grass, Tenacity killer? This is a pertinent question that constantly arises in the world of lawn care. One of the most popular questions that lawn care enthusiasts ask when deciding on herbicides or weed killers is whether it kills Bermuda grass.

The truth behind it is that despite being intended to control broadleaf weeds, many people believe that using Tenacity also destroys Bermuda grass.

However, some say that there is no reason to worry when using Tenacity on your Bermuda grass lawns. Although this herbicide may temporarily turn your lawn white or develop bleach-like spots until it wears off after a while, it does not cause permanent harm to the bladed plant since it influences Bermuda differently from other weeds.

The real promise of this herbicide lies in pre-emergent control and post-emergent control of certain weeds like Poa Annua, Crabgrass, and Dandelions while preserving Bermudagrass viability. Besides being effective at knocking out unwanted broadleaf vegetation permanently, Tenacity can also eradicate hard-to-get weeds in 2-3 weeks with its active ingredient mesotrione.

Despite opinions about its efficacy depending on soil type and growing situation for turf management professionals, experience has shown Tenacity to be an essential tool in managing dense carpets of greenery rapidly forming underneath garden plants.

Understanding Tenacity Herbicide

To understand the effectiveness of Tenacity herbicide on Bermuda Grass, you need to have an in-depth comprehension of Tenacity Herbicide. This section explores the solution to your curiosity, with an emphasis on its sub-sections. What is Tenacity Herbicide? How does it work? And, how to effectively use Tenacity Herbicide?

What is Tenacity Herbicide?

Tenacity Herbicide is a powerful product designed to control various weeds in turfgrass and lawns. Its active ingredient is mesotrione, which inhibits photosynthesis and ultimately kills weeds. This herbicide controls both broadleaf and grassy weeds, making it a versatile choice for lawn care professionals and homeowners alike.

In addition to its broad-spectrum weed control capabilities, Tenacity Herbicide has several unique features. It has pre-emergent activity, meaning it can prevent weeds from germinating before they even appear. It also has post-emergent activity, allowing it to control existing weeds in mature lawns. Furthermore, Tenacity Herbicide can be used on newly-seeded or established turfgrass without causing any harm.

Tenacity Herbicide was first introduced in 2008 by Syngenta. Since then, it has become a popular choice among turf managers due to its effectiveness and safety profile. While many herbicides have been known to cause damage to lawns if improperly applied, Tenacity Herbicide is formulated with low toxicity levels and does not pose a threat to surrounding vegetation or wildlife.

When it comes to killing weeds, Tenacity Herbicide is like the Chuck Norris of herbicides – it doesn’t mess around.

How does Tenacity work?

Tenacity Herbicide operates by inhibiting carotenoid biosynthesis, leading to the death of targeted weeds. The active ingredient, mesotrione, disrupts photosynthesis and causes oxidative damage in plants. This action is further enhanced when used alongside adjuvants that help penetrate plant cell walls.

When applied, Tenacity enters weeds through the leaves and roots, where it is then translocated throughout the plant. The inhibition of carotenoid synthesis results in chlorosis and necrosis within 2-3 weeks. Additionally, Tenacity can be absorbed by surrounding tolerant turfgrass without causing harm.

It should be noted that Tenacity is most effective when used as a preemergent herbicide or during early stages of post-emergent weed growth. Late-stage applications may not have an immediate effect due to limited translocation within mature plants.

Mesotrione was initially discovered in the late 1990s by researchers at Syngenta who were screening for new alternatives to existing herbicides. After years of testing and regulatory approval, it was released for public use in 2007 under the brand name Tenacity Herbicide.

Using Tenacity Herbicide is easier than convincing your ex to give your DVD collection back.

How to use Tenacity Herbicide?

Tenacity herbicide is a powerful tool in your lawn care arsenal, but using it incorrectly can have disastrous consequences. To ensure safe and effective use of the product, follow these six simple steps:

  1. Identify target weeds and measure your lawn or garden area.
  2. Mix Tenacity herbicide according to label instructions. Use a sprayer that can accurately apply the solution to the target weeds.
  3. Apply Tenacity herbicide evenly over the entire targeted area at the correct rate using proper safety equipment.
  4. Wait for 24-48 hours after application before watering or mowing to give the herbicide enough time to penetrate into the weed’s system
  5. Avoid contact with pets and other animals until the treated area is completely dry.
  6. Clean all equipment thoroughly after application, including gloves and clothing that came in contact with solution.

In addition to following these guidelines, be aware that Tenacity, while effective on many different types of weeds, may not provide immediate results like some other herbicides. Give it time to work—usually two to three weeks—at which point you can reapply if necessary.

A crucial point for understanding Tenacity’s strength lies in one woman’s experience: She neglected to mix the product as directed and used it around trees without proper safeguarding measures. The result? Her trees died within a year due to root exposure caused by her mistake. Don’t let this happen to you—follow application instructions closely for healthy plants and a successful weed removal experience.

Ironically, Bermuda grass may have its own tenacity, but with the right herbicide, it’s no match for our stubborn human nature.
