Residential Guide to Triclopyr Herbicide

Sick of poison ivy growing on your lawn? Want to be able to wander freely about your property without worrying about blackberry brambles clawing at your legs? Or perhaps your yard is 75% clover and you would like more grass instead. If so, it might be time to apply an herbicide that targets both woody and broadleaf plants.

You’ll have plenty of options to choose from, but when it comes to controlling woody and broadleaf plants, Triclopyr is one of the best products to choose. It works quickly and can get rid of dozens of different kinds of plants.

Here are some tips on how to use it on your property and some of the best products you can choose from – regardless of the type of weed you are trying to control.

What is Triclopyr?

Triclopyr is a unique man-made herbicide that is meant to control woody and broadleaf plants. It’s been around for quite a while, first registered in the late 1970s for use in forestry, agricultural, and non-agricultural settings. 

It can control a wide variety of plants, including docks, brambles, nettles, and other woody plants. Since it is a selective herbicide, it controls only certain types of plants. Most grasses aren’t that sensitive to Triclopyr so in most cases, you can use it on your lawn without damaging your grass.

There are more than 200 different products that contain Triclopyr, with many including other active ingredients in addition to the Triclopyr. You may find these formulated as ready-to-use or concentrated liquids, granules, or even mixable powders. They can be applied in an aerial fashion or by a ground application. 

There are even some Triclopyr products that are meant to be sprayed on plant leaves, injected or painted onto tree trunks or soil, or applied to tree bark.

You may find Triclopyr products with ester, salt, or acid forms, but all are similar in terms of toxicity and how they work. This herbicide is frequently used on pastures and uniquely, on rice paddies. It can also be used for landscaping, lawn care, and turf. 

The most common types of Triclopyr are amine and ester. These vary in terms of the species they can treat as well as the best methods of application. Ester variations tend to be best at penetrating through tough bark, making them ideal for basal bark, cut stem, and foliar applications, while amine variations are ideal for turf settings (they also drift less). 


How Does Triclopyr Work?

Triclopyr works much like other herbicides in that it imitates an essential plant growth hormone known as auxin. It causes the target plant to suffer abnormal growth, making it grow much faster than it should.

Ultimately, this overwhelms the plant and causes it to die. It is a systemic herbicide that is absorbed through a plant’s roots and leaves.

In most cases, Triclopyr takes a few weeks to fully kill a plant. 

Benefits of Triclopyr

There are multiple benefits associated with using Triclopyr on your most stubborn weeds.

For one it is a selective postemergence herbicide, targeting very specific weeds without causing harmful effects to desired vegetation. It works quickly and effectively against brushing, eliminating the need to manually pull, cut, or trim back weeds (techniques that are notorious for being time-consuming and back-killing!). 

Triclopyr works quickly, too. Although it does take a couple of weeks to fully kill a targeted species, this herbicide works faster than a common alternative, glyphosate, in getting rid of problems.

You can use this herbicide on residential and commercial properties, including on industrial sites, around pastures and rangelands, and even on rights-of-way. There are even certain formulations of this product that are designed for use on aquatic weeds! 

Drawbacks of Triclopyr

There aren’t many drawbacks of using Triclopyr on your plants!

However, you do need to be sure to read all instructions for your chosen product carefully. That’s because Tirclopyr is extremely potent and reapplying it is much easier than you might think. Be careful when applying Triclopyr near desired plants and shrubs, since it can often kill them, too.

The only other potential downside of using Triclopyr is that it acts quickly. If you need a faster method of getting rid of unwanted vegetation, you may have to try a different product (or exercise some patience) to get the job done. 

What Weeds Will Triclopyr Kill?

Triclopyr can kill many different kinds of weeds and unwanted plants, however it is mainly used to control invasive woody/vine species and ground clover. While it can kill the more common dandelions, there are better alternatives to combat these including Dithiopyr. With that said, some of the most common weeds targeted by Triclopyr applicators include:

  • Poison ivy
  • Poison oak 
  • Nettles
  • Docks
  • Brambles
  • Wild violet
  • Wild carrot
  • Kikuyu Grass
  • Plantain
  • Ground ivy 
  • Dandelion
  • Clover
  • Bull thistle
  • Black medic
  • Ragweed

…and many more!

How To Apply Triclopyr

Triclopyr is easy to apply and it works quickly and systematically, working through plant tissues and killing the plant by affecting its growth and development.

Follow the instructions on your Triclopyr product when it comes time to apply. In most cases, you will need to apply about one to four quarts of Triclopyr to about five gallons of solution or water per acre. You can apply at any time that you notice weeds actively growing. 

You should see results within two to three weeks, at which time the plant should be completely killed. However, you’ll likely notice a difference long before then, as plants may look weak and deformed before they die back entirely. 

Is Triclopyr Safe?

When used as directed, Triclopyr is perfectly safe to use. Make sure you stay off the treated area until the product has completely dried and don’t use it in areas where pets or small children might be hanging out.

Be careful when mixing or applying Triclopyr that you don’t get it into your eyes or breathe it in. It can cause serious eye damage and irritation in any of its forms. It is low in toxicity on the skin as well as if inhaled, but it can cause problems when ingested. 

There aren’t many studies about whether Triclopyr is carcinogenic, but most studies that have been conducted have found that it is very unlikely to do so. It breaks down quickly in the soil, having a half-life between eight and 46 days. It’s also non-toxic to bees, another benefit of using this product. 

Of course, you should always wear protective equipment before applying this product, too. Protective glasses, gloves, and long sleeves are a must. 


Is Triclopyr safer than glyphosate?

Triclopyr works more quickly than glyphosate and while one is not necessarily safer than the other, there are fewer plants that are resistant to Triclopyr than there are to glyphosate. 

What herbicides contain Triclopyr? 

There are hundreds of herbicides that contain Triclopyr, including Scrubcutter Grazon, Brush Off, Renovate, Victory, Release, Turflon, Pathfinder, Garlon, and more. 

What will Triclopyr kill?

Triclopyr can kill many different kinds of broadleaf plants and woody weeds including ash, alder, maple, sweet gum, sumac, bull thistle, clover, and chicory. 

How long does it take for Triclopyr to work?

Although you will begin to see the effects of Triclopyr shortly after your initial application, it generally takes about two to three weeks to ultimately kill a plant.
