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 !

SUGGESTED ADD ONS

Red Spray Pattern Indicator (Brandt Mark-It) - Keep track of your spraying and avoid overspraying with this spray.

 

Help the herbicide stick better to the weeds with surfactant such as Alligare 90 Wetting Agent

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.
does it affect dos that lick there paws and eat gras?
butch on Apr 22, 2018
BEST ANSWER: We would want to keep all pets and children of the area until the product has fully dried. Once the product has dried they would be safe to go back around the area. The product is for the use of eliminating woody vines, trees, brush and other broadleaf weeds and would not affect the turf.
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.
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.
I cut small trees and bushes with a weed eater set up with a blade. Invasive olive,multi flora,wild rose,etc. I have a back pack sprayer I wear with the weed eater. Can spray stump immediately after cutting. What is a good ratio to mix Tryclopyr to diesel fuel to kill stumps effectively?
Pat the Plumber on Apr 17, 2018
BEST ANSWER: I wouldn't waste my money on Triclopyr to deal with stumps. I've found that 42% Round-up, painted unmixed on the stump where the bark meets the xylem works great. Never had a problem with suckers after that. But if you have a lot of trees and small bushes, painting a lot of small stumps of bushes may be impractical. If so, I think it might still be more cost efficient to try Round up in a sprayer at double, triple or even quadruple the normal rate. Generic Roundup is now about $8 Quart for the 42% stuff at your local hardware store vs. whatever this site charges for Triclopyr. Don't get me wrong, Triclopyr is worth the money for many applications (e.g., wild violet in laws), just maybe not your application.
Is this the chemical that controls Oxalis?
Linda L on Jan 19, 2018
BEST ANSWER: I live in Hawaii and this is not a plant that grows wild here, but Garlon 4 is a good product to kill most of the weeds and bushes on my property. Hope this helps.
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.
I can’t kill the wild violets in my yard. All other weeds are killed with the commercial Yard treatment we pay yearly. They said they can’t kill the violets. What do you recommend?
Steve B on Sep 19, 2018
BEST ANSWER: Violets can be killed selectively with Trimec (a combination of 2,4-D, MCPP and dicamba) or triclopyr (Turflon).

So we have a problem with Yellow Archangel growing throughout a 1/3 forest in our backyard. The stuff covers near every inch of the ground (maybe 4000-5000 sq feet). We want the ground cover gone, while not damaging the trees (trees are anywhere from 50-70 feet tall). Is this product safe to use to kill the invading ground cover, but not harm the trees?
s d on Jun 13, 2018
BEST ANSWER: triclopyr 4 is a special use herbicide for situations where one has to spray lawns (it doesn't kill grass) or for resistant invasive plants like wintercreeper and porcelainberry. It can kill trees and shrubs through translocation when it's used as a foliar spray. I would use a foliar spray of about 4% glyphosate, ( Roundup) instead.
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.

To kill a large pine tree, I have been instructed to chop into the bark in a couple of places, then pour/apply Triclopyr full strength to the small stripped area. Will this kill the tree??
A shopper on Jun 14, 2018
BEST ANSWER: The best place to get advice on such things is your local Cooperative Extension Service. Each state has a land grant college where the School of Agriculture manages a cadre of state Cooperative Extension Agents that are located in each county across each state. They used to be called County Agricultural Agents. Go to the local phone book and look up Cooperative Extension Service to see if you can find it. Or go on-line for the state college of agriculture for your state. On-line you can also find many topics addressed by other states' Extension Services. I always ask my brother who is a retired county agent in Virginia. Good Luck!
I am trying to kill mulberry trees. we cut them down to stumps in the fall and it's only june and the bush is 6 ft high. will this stuff kill them off for good?
Trevia U on May 31, 2018
BEST ANSWER: I've only used it on buckthorn and prickly ash but it should work for mulberry. Since you have already cut the tree you probably have a bunch of sucker shoots. You can try either cutting All the shoots in the fall and spraying the the stumps with a 4:1 mixture of diesel fuel and triclopyr; or (my preference) use the basal bark method and wait until late fall then spray completely around the lower 1 foot of all suckers with the 4:1 mixture. I use a cheap spray bottle from the Dollar Store. But the stuff really works.
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.
Will Garion 4 kill large Australian pines? Diameter over six inches. If so what is the best way to apply? Drill hole? Paint on bark?
Glenn O on Aug 17, 2018
BEST ANSWER: Short answer, I don't know/haven't tried. No literature I've read said whether or not it is choice for pines. I've only read glyphosate on pine leaves or cambium (after cutting down). I'm 'guessing' it ,maybe, has something to do with mono-filament leaf characteristic (like grass). If you find triclopyr effective on pines, I'd really like to know.
Have a Broom problem here in Northern California along with the typical poison oak and blackberry. What strength Triclopyr should I start with?
jeff p on Mar 14, 2018

I want to kill a large conifer. I have a 1 gallon tank sprayer and am planning to use diesel fuel mixture. What should the ratio be?
Richard N on Aug 20, 2018
BEST ANSWER: Your one gallon mix should be 80% Diesel and 20% Triclopyr 4 herbicide. In other words, 102 oz. Diesel fuel & 26 oz. of herbicide. I use this mix all the time for treating cut stumps or for chainsaw girdling trees, in which case you would spray the mix into the cuts.
I'm killing cactus and mesquite and been mixing with water. I'm hearing through your messages that you suggest mixing it with oil instead of water. Is this correct for what I'm trying to kill? If so mix it with diesel?
Shirley G on Jun 29, 2018
BEST ANSWER: In our area we mix one part trychlopyr to four parts horticultural oil (it has a red dye added so you know what youve treated). We then use this as a spray on the trunk base or onthe cut ends of stumps. Not sure how it would work on yoir things

A shopper on Dec 5, 2017

Will it kill cane?
Wingnut on Jul 29, 2018
BEST ANSWER: We don’t have much cane in Michigan but it kills Sumac which is a 2-3 year project. Garlon 3a (triclopyr3a) has been recommended as the broad leaf killer with 4 as the root system follow up killer, but so far the tric 4 has leveled everything in its path.
I treated my terrace in late May. Is it safe to plant blue juniper in September?
Michael T on Jul 3, 2018
BEST ANSWER: Yes, it will be safe to apply the blue juniper in September if the Triclopyr 4 was applied in May.
Hi do I have to mix tryclopyr with water and then diesel to kill a stump or is it pure diesel and the chemical?
A shopper on May 30, 2018
BEST ANSWER: Don't add water - it doesn't work if you do. I just use the Triclopyr with a surfactant. You can do up to half and half but I prefer 2/3rds Triclopyr and 1/3rd surfactant.
Will it get rid of carrot weed?
Dale F on Mar 27, 2018
BEST ANSWER: Yes, Triclopyr 4 will kill wild carrots and Queen Anne's Lace.
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.

Winter program for killing Kudzu
This stuff works very well if you use it mixed with a surfactant (up to 50/50) and no water. I also added a blue colorant so I could see where I'd already been kudzu fighting. A little of this stuff goes a long way. I cut back the kudzu when it is in the dormant stage, all the way to the mother root and then I use a drill to drill the exposed root full of little holes and then I spray this solution into the holes and cuts. So far, so good. If you do this in the growing season, the root will sometimes throw out dwarfed kudzu leaves. That is easy to come back and spray with Crossbow or Clopyralid 3. The kudzu shoots thatyou remove when cutting back, should be removed to a pile somewhere and either burnt or chipped. Otherwise, it will grow back and make more shoots and that means you just propagated a whole new mess of kudzu! At least Kudzu isn't poisonous like poison ivy, or has thorns. It could always be worse. Solutions pest and lawn has these products at the best value for money around.

Triclopyr Overall Best Herbicide That I Use
I have used hundreds of gallons of Triclopyr over the past many years keeping my pastures clear of unwanted weeds, briers, and brush. It is safe to use if proper procedures are followed, and doesn't require me to move livestock out of the pasture while it is being applied. It is somewhat slow acting, so don't expect immediate knock-down results like with 2,4-D. However, in my experience, Triclopyr is not as volatile as 2,4-D, so it can be applied closer to desired vegetation without the higher risk of drift. I can't imagine trying to farm/ranch with pesticides, and Triclopyr is my go-to herbicide.

Great product
Just love it !!!!!!! I had a few big California fan palms, and while trying to decide if keep them or not , a lot more that were not invited started to grow into my front and back yard, it was pretty difficult to get rid of them. So, when I found Triclopyr 4 and started using it my problem was solved.It takes three to four weeks to kill the big ones and the small ones are gone in a week, now just have to keep an eye on new sprouts as I do with any other uninvited weeds.

Clearing Brushy Areas, Overgrown Flower Beds Around Old House
I used Triclopyr mixed with store brand vegetable oil to make it stick. Cut small trees and brush 1-2 inches from ground and paint cuts with the mixture. I did it this way to be selective in what I killed. Take care in using it this way. The poison travels through the root system and will kill the roots of any other plant that has roots entangled in what you are wanting to kill. And kill it does. All trees, Oriental Bittersweet, Trumpet Vine, Poison Oak & Ivy. Excellent product.
