Triclopyr is a man-made herbicide used to control both broadleaf and woody plants. It was first registered in for use in forestry and it is used in both agricultural and non-agricultural settings.
Certain products may have limited use for campsites, roadside applications, and some ornamental lawns. Always read the label for your product's use sites and instructions. Broadleaf weeds often controlled with triclopyr include nettles, docks, brambles, and woody plants.
Triclopyr is a selective herbicide, meaning it only controls certain types of plants. Grasses tend to be less sensitive to triclopyr than other weeds.
There are over products containing triclopyr. Products may be ready-to-use, concentrated liquids, granules, or mixable powders. Products with triclopyr can be applied aerially or by ground application. They may be applied on tree bark, injected into tree trunks or soil, or sprayed on plant leaves. Products with triclopyr may have acid, salt, or ester forms.
These forms tend to behave similarly in terms of toxicity and their movement in the environment. Triclopyr is commonly used on pastures and rice. It is also commonly used for turf, landscaping, and lawn care. Triclopyr is a systemic herbicide. It affects actively growing plants by mimicking a specific type of plant growth hormone, known as an auxin. It causes uncontrolled plant growth and plant death.
If you are in an area during or shortly after application, you could contact it, breathe it in, or get it in your eyes. Most triclopyr incidents that were reported to the US Environmental Protection Agency EPA from to involved homeowners who were mixing or applying products. While accidents can happen, following label instructions and taking steps to minimize exposure can help reduce risks.
If any exposures occur, be sure to follow the First Aid instructions on the product label carefully. For additional treatment advice, contact the Poison Control Center at If you wish to discuss a pesticide problemplease call The salt form of triclopyr can cause permanent eye damage. The ester form of triclopyr may cause eye irritation. All forms of triclopyr were low in toxicity on the skin. Triclopyr is low in toxicity if inhaled. If eaten, triclopyr is low in toxicity.
Triclopyr is not absorbed well through the skin. A study with rabbits measured that 1. Triclopyr residues were measured in fat, ovaries, livers, and kidneys of rats that had eaten triclopyr. Triclopyr mainly leaves the body in urine. More studies may be needed to determine if triclopyr exposures could be linked to human cancer risks.
The EPA has determined triclopyr is "unable to be classified as to human carcinogenicity.Forums New posts Search forums. Media New media New comments Search media. Members Current visitors New profile posts Search profile posts.

The answer is yes, Ric LawnSite Fanatic. Location S W Florida. Runner said:. Ric said:. Last edited: Sep 2, Grandview LawnSite Gold Member. Location WI. I have found Lesco Three Way to be rain fast within minutes for a light rain. A down pour you want an extra 30 minutes. I meant good to go for the application NOT the respray for the op. You mentioned that it was "Anamine" or something like that. Did you mean Amine? This is just the type of formulation it is, But for future reference?
I'm certainly not shy or bashful about sitting down on some boxes at my supplier and peeling the label book back.
Location Indiana. I agree 1 hr. Location Grand Rapids MI. Herbicides work faster at higher temps. Absorption is better at higher humidities. But a lot depends on the type of weed and growth conditions.Hi-Yield Turflon Ester Ultra is labeled to eradicate wild violets.
Please refer to the product label for complete mixing and application instructions. You can apply this product early spring through fall for the most effective results.

Hi, I was wondering how much do I use per gallon in a hand sprayer? I'm not very good in math so oz per acre is foreign to me. For specific application instructions, please refer to the product label. Was this answer helpful to you?Homeowners can learn the correct procedure for controlling woody invasive plants with the cut stump treatment method—a simple way to control woody invasive plants.
An herbicide solution is applied directly to the stump top immediately after cutting down the plant. Cut stump herbicide treatment is a simple way to control woody invasive plants. The herbicide kills the stump and prevents new growth that would normally occur after cutting alone. Cut stump treatments are most useful where the target tree or shrub density is relatively low, manual labor is available, and dead standing trees and shrubs are not desired. This method can be used selectively with no damage to surrounding vegetation.
Cut stump treatment is not recommended where thousands of stems per acre need to be treated or where trees or shrubs cannot be safely felled and piled if needed.
Cut stump treatments are an effective method for woody invasive plant control. The cut stump treatment method is effective on almost any size woody invasive plant including large woody vines. However, small stems less than a half-inch in diameter are not consistently controlled.
Cut stump treatments can be done almost any time of the year with most woody invasive plants. While late summer through fall is often the optimal time, late fall may be the easiest time from an operational standpoint. Temperatures are cooler, herbaceous vegetation is dormant, and undesirable critters are less active. The only time cut stump treatments should not be done is in the early spring when trees are experiencing strong upward sap flow. For larger stems, you typically need a good chainsaw, although a lightweight brush saw is fine for smaller stems.
A handsaw or pruning shears are adequate for smaller stems as well. Cut stump herbicide treatments are most easily applied with backpack sprayers or handheld pressurized spray bottles, but they can also be applied with a paintbrush. The best option is to cut close to the ground, leaving a one- to two-inch stump. It is best to treat immediately after cutting, within a few minutes at most. Delays in treating may reduce effectiveness.
Many stores have two effective herbicide active ingredients available for homeowners. These are glyphosate and triclopyr. Products may vary in the concentration of these active ingredients, so look closely at the label. Ready-to-use glyphosate products with less than 20 percent active ingredient will not consistently work for cut stump treatment.
Glyphosate products with 20 percent active ingredient can be effectively used but should not be diluted. The most cost effective option for larger projects, however, is to use a glyphosate product that has 41 percent or higher active ingredient. For the 41 percent or higher glyphosate products, mix an equal amount of herbicide with water to make a 50 percent solution.
Ready-to-use triclopyr products with less than 8 percent active ingredient will not consistently work for cut stump treatment. Triclopyr products with 8 percent active ingredient can be effectively used but should not be diluted. For either glyphosate or triclopyr, a small amount goes a long way when treating stumps.
It is ideally used to thin out forests, clear grass pastures, rangelands, and public highways. Triclopyr 4 works systemically, absorbing through the leaves and roots of the plants and interfering with their growth. When trees or broadleaf weeds are obstructing the view of roads, slowing down a construction project, or crowding a residential area, applying Triclopyr 4 Brush Killer can be a useful solution. To use Triclopyr 4 Brush Killer, you will need a skid sprayer to cover large areas.
For smaller jobs, you can use a hand-held pump sprayer or backpack sprayer. Triclopyr 4 Brush Killer can be used in forests, on permanent grass pastures, rangelands, conservation reserve programs, manufacturing or storage sites, along paths of power lines, telephone lines, pipelines, railroads roadsides, and fence lines. It can be used to eliminate various types of trees, perennial bluegrass, perennial ryegrass, and tall fescue ornamental turf, such as sod farms, commercial turf property, and golf courses.
Triclopyr can also be used to clear unwanted trees and brush away from building sites and residential properties. Apply Triclopyr 4 Brush Killer during calm days, when rain is not in the immediate forecast.
It is also great to use before building projects begin or when phone lines, power lines or roadways are blocked.

Forest Service forest inventory and analysis data indicate the tree species composition of Pennsylvania's forests is changing. One indication of change is understory composition. Inventory data show that understory tree species are not the same as those found in the overstory. Species such as northern red oak, chestnut oak, white oak, and white pine that occupy the overstory are not well represented in the understory.
By comparison, understory abundance of some species like red maple Acer rubrumAmerican beech Fagus grandifoliablackgum Nyssa sylvaticastriped maple Acer pensylvanicumand black birch Betula lenta is increasing.
When forests are disturbed, either by natural or human-caused events, the existing understory species have the potential to change the composition of the next forest. Recognizing and treating potential species composition changes using properly applied silvicultural practices is critical to forest sustainability. Controlling interfering plants prior to a planned harvest can increase the proportion of desirable species that regenerate successfully.
Depending on ownership objectives, it is often useful to remove or target undesirable tree species, favoring species better suited to the site and future desired conditions.
Timber stand improvement practices, when properly applied, will shift species composition to meet landowner objectives and site conditions. Herbicides are a versatile tool for manipulating tree species composition. Selective herbicide applications offer one of the safest, surest, and most efficient means for controlling unwanted understory tree species. Herbicides can control unwanted seedlings and saplings using directed foliar sprays, tree injection, and basal bark sprays.
Always read and understand the label before using any pesticide. Basal bark herbicide applications are made using a low-pressure backpack sprayer to thoroughly wet the lower inches of the stem using a solid cone or flat fan nozzle. To be effective, it is important to thoroughly wet the entire stem, root collar area, and any exposed roots.
Basal bark herbicides use an oil carrier commercially available basal oil, diesel fuel, no. Trees with thick or rough bark may require increased coverage to be effective.
Numerous products are labeled for use as basal bark applications Table 1. Triclopyr ester is the active ingredient used. It is found in products such as Garlon 4 Ultra and Relegate. Triclopyr ester is a systemic herbicide, absorbed by the plant and translocated to tissues remote from the point of application.DO NOT burn off, cut or clear blackberry or other woody weeds for at least six months after spraying.
