TSI herbicide

[squackattack]

Have y'all had much success using straight glyphosate with hack and squirt. I have a partial jug and wanted to use it up instead of buying a jug of arsenal. Elm, ironwood, gums, and red maple are the target species.

 

[TnKen]

I've not used glyphosate so I can't comment. I have used Arsenal and Tordon rtu. I seem to get a faster kill with the tordon and will probably go back to it after I use up the Arsenal.

I didn't use it straight, but last year I used a heavy dose of cornerstone and crossbow mixed up and none of the thorn trees I sprayed died. Actually, other than weeds and briars, I don't think it done anything to any bushes. Someone here had a video on the chemicals to use but it's slipped my mind on what was actually recommended. But it was 2 herbicides.

That's it! Thank you

I used Gly two years ago on mostly maples and black cherrys with 40-50% success.

 

[BSK]

I use a 50% glyphosate concentrate and 50% water. Kills pretty much anything but not mature trees of any species. So far, I've found NOTHING that will kill mature trees, including double girdling.

 

[Boll Weevil]

BSK, not even Garlon 4a? I've had great luck with it on thin barked trees like beech, maple, myrtle, and privet. Diesel as the carrier/penetrant it'll smoke those species.

I've got some big beeches double girdled, hack and squirted, drilled & herbicide applied, and girdled and squirted. Going to have to wait and see if they leaf out this spring and figure out if any method is successful.

I've had extremely poor results from Garlon 4A. Wouldn't kill anything. I've even tried mixing it with Imazapyr and glyphosate and none of those mixtures worked as well as just glyphosate concentrate.

 

[BSK]

I'm actually surprised Craig recommends mixing Garlon with Imazapyr. I used that mixture, killed virtually nothing, and then a TN Forestry person told me those two chemicals counteract each other and won't produce a good kill with hack-and-squirt.

 

[Ballerski]

I've use gly and water with good results anytime past October. Upon recommendation, I've tried gly, water and diesel and results seemed the same as 50-50 mix.

I've used Arsenal AC on some monster sweet gums with good success. Girdle with chainsaw and then wet the cut down.

 

[squackattack]

I have used arsenal ac, garlon 4, tordon rtu with some success. Just never used glyphosate. Seems like it would be cheaper too.

 

[rukiddin]

1/2" hole angled down in the tree at base with a shot of tordon in the hole kills every time for me. Bradford pear, elms and hackberry make up the majority of what I'm killing.

 

[LanceS4803]

In the last few years I have killed literally thousands of trees on my property (sweet gum, red maples, beech, black gum and privet) with outstanding success. From saplings to monster sweet gums.
Garlon 4 for hack & squirt
Garlon 3 for basal bark
Both mixed to insert instructions.
What is great about Garlon 4 is that it will not cross species with entangled root systems. As in, I H&S a sweetgum that is growing together with an oak. It will only kill the sweet gum.

What concentration of Garlon 4?

 

[LanceS4803]

50/50 with water (per instructions) and generally follow the recommended hacks per inch. I used blue marker dye at first, but it is easy to tell which trees I hit, as I do them all at the same height.
I have run into a few trees that the H&S didn't seem to "take" with one application.
And I have one tree that is on it's 3rd attempt! Weird that on each of the previous ones the tree vomits up that sweet smelling yellow goo, and areas around the hack start to rot, but the darned tree will NOT die! But that is a very rare exception.

I had this happen on virtually every tree I H&S last September with Triclopyr. It frustrated me so much - I treated about 2 acres. I have some huge projects coming up in October. I even went and bought a small arborist chainsaw for girdling and doing this every fall. Now it is just making the right herbicide concoction.

How long did it take to see results on the big trees with Arsenal?
I have seen results on the smaller trees, but the bigger ones are not showing anything after about a month.

 

[squackattack]

With arsenal I see results within a month, bigger trees may take longer but they are dead they just don't know it. A lot factors though, I find with higher temperatures you see faster results.

 

[Popcorn]

Herbicides like gly and crossbow are intended to effect the the plant via the leaf which has pores called stomata. Some stomata only open when the sun shines on them and many close under adverse conditions. I would not expect these type products to work very well applied any way other than the leaf. I have used gly mixed with crossbow and reward plus some crop oil and via leaf application that blend has yet to fail me on any problem tree or anything else.

3A is for hack and squirt, 4 is for basal. 3a is water based, 4 is oil soluble.

A lot of times imazapyr won't show until the next spring but it usually kills once you get it under the bark

That's what I was hoping. I have applied way more than the recommended amount on some of the big beech trees.

Yeah, got those backwards.
That's what I get for not checking before writing!
