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.
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.
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.
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.
Will Triclopyr 4 kill common house/ornamental plants like ferns and palm trees?

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.

How do I mix teoclopyr in order to kill hardwoodS that have sprouted in my young long leaf stand?
David A on Sep 27, 2017

6 quarts of Alligare Triclopyr 4 in a minimum spray volume of 5 gallons per acre. To improve
woody plant control or broaden the spectrum of woody plants controlled, follow label directions

I recently purchased your Triclopyr 4 Brush Killer (Garlon
4) to treat my lawn that has a decent amount of wild violet
and creeping charlie. Can you advise on the mix
concentration (with surfactant) and rate of
application using a 2gallon manual pump sprayer?
A shopper on Sep 7, 2017
BEST ANSWER: Mix 3/8 to ¾ ounces of Alligare Triclopyr 4 per 1000 square feet in enough water to provide uniform coverage of the target area and apply at any time broadleaf weeds are susceptible. Note: Do not apply more than 2 quarts per acre or 1.5 ounces per 1000 square feet of Alligare Triclopyr 4 in a single application.

Don G on Sep 1, 2017

some areas, but this is extremely laborious.

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.
