Triclopyr 4 Brush Killer (Garlon 4)

Control Invasive Brush Conveniently and Inexpensively with TriclopyrTriclopyr 4 Brush Killer (Garlon 4)

Here at Solutions Pest and Lawn, we get a lot of customers that contact us who are dealing with tough broadleaf weeds invading their vegetations and crops they are trying to grow. More often than not, we recommend them to try Triclopyr to eliminate those hard to control weeds that ruin their gardens, ranges and pastures. Triclopyr does a fantastic job in tackling woody species and brush while being very economical in price.


What Is Triclopyr?

Triclopyr is a selective herbicide which targets broadleaf plants (like forbs, shrubs and trees) and can be used in grasslands or areas where desirable grasses are growing under or around targeted woody or broad-leaved invasives.


There are two forms of Triclopyr--amine and ester--which vary in terms of the species they can treat and methods of usage. Solutions carries the ester variation which is best for penetrating bark and can be used for foliar, cut stem and basal bark applications. Triclopyr 4 Brush Killer is the same product as the popular Garlon 4 herbicide.


Why Triclopyr is the best brush removal strategy.


Depending on certain conditions and disturbances in the environment, woody species like buckthorn, honeysuckle, poison oak and other types of invasive brush spring up where they aren’t wanted and interfere with the growth of desired vegetation. Sometimes even trees and vines creep up unexpectedly baffling customers and force them to come up with a removal strategy.


Non-Chemical strategies, like manually pulling or cutting down the invading weeds and mechanical removal can usually be hit or miss depending on the type of weed or brush that is growing on a property. It is also usually very labor intensive, expensive and time-consuming. That is why using a chemical control method like Triclopyr is highly recommended for those who want to save time, money and energy over other methods.


Products like Triclopyr are professional grade and are much more effective than what you would find at your local department store or gardening center. Most products sold for brush control at garden stores are a combination of two or three growth regulator herbicides intended for foliar applications. These products also typically contain lower concentrations of active ingredient. Products containing Triclopyr is much more concentrated and is more effective on woody species than those based on 2,4-D, dicamba or other herbicides.


Solutions Step-By-Step Guide for Triclopyr

Before handling Triclopyr, we recommend you wearing protective eyewear and chemical resistant gloves in addition to long-sleeve shirt, long pants, shoes and socks, during mixing and application as Triclopyr is known to cause skin and eye irritation.


For Controlling Brush

1. We recommend using 3.2 oz to 6.4 oz per gallon depending on the size of the brush. One gallon of mixed solution which should cover about 2 acres of land.

2. We would recommend using a surfactant when using Triclopyr as it will help enable the product to stick to the foliage and give you better control.

3. Mix the product and spray evenly onto the brush until it’s fully coated.


For Controlling Trees


1. Mix one part of Triclopyr with four parts of water.

2. For any tree trunk size that is less than two inches in diameter, start applying the Triclopyr beginning at the ground and spraying up three feet up on the trunk of the tree, spraying to the point of run off.

3. For any tree trunk size that is more than two inches in diameter, take a machete and make a cut into the trunk into the tree right into the cambium layer and then peel away at the outer bark and then spray the trunk of the tree with the product.



Following the above steps accurately you will be certain to see results within days as the brush and weed will start drastically wasting away. Now that you see how it’s done, order Triclopyr today to take care of your weeds and trees.

the secret to the perfect lawn is just a click away !

Does Trilopyr 4 kill Autumn Olives ????
I have an uncontrolled growth of this terrible invasive plant from asia on my CRP sites. Do you recommend something mixed with Trilopyr and applied to the bark at the base of the plant ? Need help for this proble
Billy in Indiana on Jun 4, 2017
BEST ANSWER: I'm fighting 10 acre autumn olive jungle. I mix 13oz. triclopyr per gallon of diesel and throw in 4oz MSO (MES 100) for good measure. Spraying trunks up to 4". Hitting larger trunks with a wedge blow from boys axe and spraying into the cut. Works good but slow progress when you're dealing with acres. On big bushes, also spraying smooth bark branches at base helps effectiveness. 4 oz in gallon of water, w/ MSO, as foliar spray works on new sprouts up to three ft. or so.
If I remove a tree do I put garlon4 in the cambeam layer to kill the tree?
A shopper on Sep 15, 2017
BEST ANSWER: If you cut the tree as close to ground as you can, you can either spray garlon on the surface of the stump or brush it on with an old paint brush. It will prevent any shoots from sprouting and eventually (several years) the stump becomes brittle and simply breaks down.
How well does this work on Chinese Privet and at what strength would you recommend ?
William C on Nov 21, 2017
BEST ANSWER: Foliar applications are effective on privet where complete coverage of all leaves is achievable. Glyphosate is recommended as an
effective foliar herbicide for privet. However, higher spray concentrations are needed for privet than for other brush such as multiflora
rose, for example. Based upon a formulation that is at least 41 percent active ingredient, prepare a 3 percent mixture of
glyphosate in water (4 ounces per gallon of water) and apply as a high-volume foliar spray with a hose and handgun sprayer.

Cut stump applications are practical in situations where infestations are of low density,
where damage to grass or other nearby vegetation needs to be prevented, or where bushes
are too tall to achieve complete foliar coverage. Effective options include
Garlon 3A (triclopyr amine), Remedy Ultra (triclopyr ester) and glyphosate. For larger brush, mix 6.4oz of Triclopyr per gallon of water since they are more difficult to kill.
Is this the chemical that controls Oxalis?
Linda L on Jan 19, 2018

Will triclopyr 4 kill rose hedge?
Tommy C on Aug 15, 2017
BEST ANSWER: Rose hedge is not on the label for this but many people do use it for it. Typically they mix with diesel and spray around october (if you are in texas) for best results. We recommend Imazapyr 2SL as it has wild rose on the label. Whatever you do, DO NOT mow it until you have applied a chemical to prevent spread. It will spread if you mow it without stopping growth.

I’ve bush hogged my field in middle Tennessee, it’s almost thanksgiving, can I still use triclopyr?
Jim T on Nov 18, 2017
BEST ANSWER: Don't know about specifics for Tennessee. All I can offer is that here, in Minnesota, creeping charlie took over our entire lawn (we have 4 acres, 1/2 give or take), over the course of winter. We raked in the fall, and in the spring, it was EVERYWHERE! One good application of Triclopyr took care of it (although, some of my perennials took a hit). Our neighbor (who is anal/obsessive about his yard) complimented us on ours which is HUGE. It took all summer, but our lawn is back! I recommend this product for anyone who is fighting the battle of the weeds.
When I mix in a pump sprayer how much MSO/surfactant should I add to the water/ tryclopyr mix?
Joanne G on Oct 17, 2017
BEST ANSWER: We used approximately 3 oz. Tryclopyr per gal of water. This was a strong mix, but we had an aggressive creeping Charlie problem. Adjusted mixture to density of weeds (i.e. areas of all weeds/areas of weeds mixed in grass). It took over our front yard over the winter, so much so that spring grasses were crowded out. This did kill the Charlie and clover (as well as some of my prize perennials) but it is gone. New seed, lots of watering, and our yard is back.
how many ozs is this?
mark a on Dec 19, 2017
BEST ANSWER: It is one gallon. You dilute it with water or diesel fuel. The amount depends on what you're trying to kill.
is this a restricted spray?
A shopper on Dec 5, 2017
BEST ANSWER: No. Tricclopyr is not restricted and does not require any license to purchase.
Once mixed into an oil solution, is the triclopyr stable and effective for say 2-4 weeks if stored mixed?
Nicola M on Nov 7, 2017
BEST ANSWER: I can't say about oil. I blended it with other chemicals in water and found it was not stable. It formed a milky suspension that settled into white granules over time. If I mixed right at time of use, all was well.
What is the lowest temperature at which this product will be effective? Wisconsin land owner--high temp tomorrow 41 degrees.
dave d on Oct 28, 2017
BEST ANSWER: Read the label for manufacturer instructions typically weed control is effective as long as the plant is actively still growing once you've had a frost or two most plants start shutting down and will not actively take in the product here in Michigan we are still spraying this week with a temperature of between 40 and 45 degrees
My lawn care company treated my lawn with this product to remove wild violets. How long after its application can I reseed with fescue?
A shopper on Oct 7, 2017
BEST ANSWER: 3 weeks is correct. But you may want another application of triclopyr before reseeding. I found Triclopyr effective, but with wild violets, you inevitably will need a second application.
If you are in parts of the south, you have experienced drought and should probably wait on the second application until we get some rain. Triclopyr should not be applied when the grass is under stress, although I'm guessing this rule is relaxed in the fall when temperatures are down. Check with your lawn care company for their opinion on local conditions. Otherwise, I've been successful reseeding well into November here in Richmond, VA.
How long do you leave the tree after you spray it with triclopyr?
A shopper on Oct 6, 2017
BEST ANSWER: I use it on Buckthorn up to 4 inches thick. I wait at least one full year and then check to make sure the branches are dead and snap off .

Will this work on stinging nettles? If so how best applied and will it harm the grasses?
A shopper on Jan 29, 2018
BEST ANSWER: There does not appear to be any selective herbicide that will control the nettle. Recommendations are to use a Glyphosate product. This will kill the grass, so you will have to apply as a spot treatment.
Best to apply during the active growing season of April and October.

kills the buckthorn
I use it right after the other flowers in the fall die back. Hit the little buckthorns and then come back later with a little higher concentration mixed with kerosine and spray the bark of the larger ones. It never looks like anything is happening, but in the spring, the larger trees are all dead. Great stuff

Violet Killer
The brush killer (violet killer) does kill the weeds but only partially killed the violets. The violets were ingrown with my grass and it seems to have made more of an impact on killing the grass than the violets. Spraying everything did a good job for the first time. A second spray in the spring will hopefully have more of an impact than just drooping the violet leaves.
