Triclopyr

Invasive weeds like Buckthorn, Honeysuckle, Poison Oak and other types of invasive brush can often spring up where they are not wanted and interfere with the growth of desired vegetation. When this happens, using non-chemical control methods like manual pulling or cutting may not be an effective solution. That is why when you want the brush gone you should consider Triclopyr to clear out those weeds.

More often than not, we recommend them to try Triclopyr-based products to eliminate those hard to control weeds that ruin their gardens, ranges, and pastures.

What is Triclopyr?

Triclopyr is a selective herbicide that works to control broadleaf weeds and brush and can be used in areas where desirable grasses are growing under or around invasive woody plants.

There are two forms of Triclopyr--amine and ester--which vary in terms of the species they can treat and methods of usage. Solutions Pest & Lawn carries the ester variation which is best for penetrating bark and can be used for foliar, cut stem, and basal bark applications. Amine variations are better in turf settings and when drift is a concern. The active ingredient has also been used as an aquatic herbicide for some weeds which grow on ponds and lakes. 

How Does Triclopyr Work?

Mode of Action

Triclopyr’s destroys targeted plants via imitating an essential plant growth hormone (auxin). Triclopyr's auxin imitation makes it so the target plant suffers abnormal growth. The affected plant grows faster than normal which overwhelms it and causes it to die.

Benefits of Triclopyr

Triclopyr is a selective post-emergent active ingredient, meaning it targets specific weeds and largely brings no harmful effects to desired vegetation in close proximity to when applied. Triclopyr is also useful against brush sparing the need to use non-chemical methods to remove brush like manual pulling or cutting which can be labor-heavy and time-consuming. Triclopyr has demonstrated that it works faster than Glyphosate when it comes to killing problem weeds.

Use Triclopyr for weed and control on residential and commercial areas, industrial sites, rights-of-way and around rangelands and pastures. You can also use variations of this active ingredient to treat certain aquatic weeds.

Drawbacks of Triclopyr

Triclopyr is a very potent product so be careful not to overapply and be careful applying near areas where your desired ornamental bushes and plants are. Triclopyr is also slow-acting so those who desire a faster kill of unwanted vegetation will have to be patient or try a different product for their target weed.

Is Triclopyr Safe?

Triclopyr is safe to use when applied carefully according to label directions. Keep off of the treated area until the product has fully dried.

Please use protective equipment (PPE) before applying Triclopyr. Gloves, protective glasses and long sleeve clothing should be the minimum level of protection when handling this chemical. Please refer to the product label for specific safety instructions.

What To Expect

When applied, Triclopyr works systemically, moving throughout the plant tissue and killing the plant by hindering plant growth and development processes. Following treatment, the affected plant will suffer abnormalities and look deformed before slowly dying within two to three weeks after application. 

To improve its killing power and the range of plants it can kill, you can choose to mix Triclopyr with other herbicides such as Glyphosate. Check the label to see which specific herbicides are approved for tank mixing.

For more persistent weeds, follow-up applications may be necessary to get complete control.
