Hack and squirt recipe

The state foresters here recommend Triclopyr 4 - the cheaper generic of > (Garlon 4) mixed with diesel, especially for over-winter killing action. Spud mentioned the reason for diesel above in post #16 - it doesn't freeze like water-based treatments, and the oil penetrates the bark for better killing action - all winter long. Our foresters told us that if we wanted more invasive trees to croak over winter, to use Triclopyr 4 and diesel. Our invasive problem is TOH ...... tree-of-heaven. Triclopyr 4 + diesel fries 'em!!! - - - - - FWIW

It also fries chinaberry and sweet gum ( quickly)

BTW ... I do not hack into the tree. I just squirt the solution around the base of the tree. The diesel acts as a penetrant and will draw the mix into the tree.
I will be going to war with acres of BH, MFR, privet, burning bush and Olive this spring...is there a way to apply this with a sprayer or the viscosity it too thick?

That's how I did mine. I used a 4 gallon backpack sprayer. I did a 3 to 1 mixture of diesel to triclopyr 4. I added blue dye. I used a long paint mixing blade to a cordless drill, and mixed it well. I went through 22 acres in a couple of days, working all day long. The forester painted the trees ahead of me.

3:1 Triclopyr to diesel? I use the opposite ratio, 3:1 diesel to Triclopyr and have had good kill results. Curious why you us the ratio you use?

That's why I use old dish soap bottles, no clogging. I tried a sprayer and had too many issues with clogging especially in the cold months.

Yep, 3 gallons of diesel to 1 gallon of triclopyr 4. Sorry about that. That makes a huge difference. I'll edit.

.......then load in a 4gal 28$ backpack sprayer from harbor freight and head for the Sweetgum stands

I am going to go nuts from the trails i opened with this every year. just keep whittling them back more and more and more....
 
We used H & S method using trigger-spray bottles from H Depot. Couple of $$ for the bottles - adjustable spray nozzles. Triclopyr 4 + diesel ......... 2 of us killed about 300 to 400 TOH in about 5 hours. Adding blue dye helps you see where you already sprayed.
 
Anyone have any luck doing this to get rid of buckthorn? I'm noticing I have a few spots and want to try whatever I need to keep it at bay if possible.
 
Triclopyr + 2,4 D.

I haven't done the diesel basal spray yet, but I'm going to give it a go this winter on some honeysuckle and callery pear.
 
Triclopyr n diesel is what I do. If you close to a nice oak, you can just duble gridle and use straight diesel. I also have the green tordon rtu when near trees I want to not kill. More use that lightly with grape vines on trees I want to save. More mature trees than not grow back from cut stumps. The young growth is great for winter forage if the specieis is right. If you don't want it to grow back cover the outside layer of the stump with diesel, green tordon, or triclopyr mix.

General, general rule of thumb, smooth thinner bark species can be killed by applying some of that triclopyr n diesel. Hack n squirt good trick is to get a rounded axe face, chop a little pocket tat can hold your chemical.

Chainsaw girdle, just 2 complete circles within lets say 2 or 3 inches from each other.

Also, spring is a bad time to do this. Sap flows. Some trees have flows during warm spells in the winter when you want to go outside.

If lower stuff looks very well browsed, higne cutting isn't a bad idea at all. Depending on the species. ONly downside is it can make a mess to clean up a few years later. Not a bad thing to do near entrances of seclusion zones. I do it lightly at my hunting lease. They are easy going, but the main prupose of that land is logging. So I don't overdo some things over there.

Yep .... State foresters here told us fall - Sept. and Oct. - are prime time to H & S unwanted trees. Sap is dropping into the root systems to store energy for winter, taking triclopyr along with it. FWIW.

How did I not know about this? Does it work on aspen?

How does it look now?

It worked great. Here's a clump of Tree of Heaven I killed by basal spraying. This is from the first fall after spraying that spring. I wish I'd have taken some pics this past spring. I do need to go heavier with thinning in some areas. Screenshot_20241128_205514_Gallery.jpg

This is basal application I use it on Osage Orange with great effect.

Fwiw, I’ve seen chinaberry have the highest preference of any stump sprouts out there. Have you ever flush cut and allowed to resprout?

I have not done that

I'll give it a try and see what happens
