Brush killer

Phil Tibbetts · Jun 14, 2021

I'm trying to find a good brush killer. Years ago we could get some stuff to mix with diesel fuel but can't find it anymore. I suspect it has been taken off the market for environmental reasons. That was a one shot deal and the end of regrowth where used. So my question is what do you folks recommend as a good brush killer now? I have a lot of gray birch and aspen that I cut one year and the next year they come right back up.

Ive had good luck with the brand Crossbow.

What is it mixed with if anything?

Geo-TH,In · Jun 14, 2021

Most sprayers won't handle diesel or oils.
I use 2-4-d. Recently sprayed driveway with 1 oz 2-4-d per gallon and it killed weeds. It was a hot day after I sprayed.
I mix 2 oz per gallon to kill honeysuckle after we cut it back and it starts growing again.

I look for the most concentration of 2-4-d at RK
Same with roundup. The name doesn't count. concentration does.

Crossroads is the generic for crossbow. Both are great.

Don't know about 24 D but regular round up has no effect on birch and aspen. Good on dandelions and plantain leaf .

I cut down a large sycamore tree. New sprouts came off the side of the stump. A couple applications of 2-4-d killed the tree.

Active Ingredient in crossbow : 2,4-D, butoxyethyl ester 34.4% Triclopyr, butoxyethyl ester 16.5%

Guess I will give the 2 4 D a try. Thanks for the info.

Simply any old brush killer at your local farm and garden store. They are pretty much all 2-4-D. Just as the instructions tell you, dilute and spray on young growing plants, or apply concentrate to the stump of a plant that you cut, in order to kill the roots.

Garlon 3 or Garlon 4

What works real well for me on brush that we cut with a chain saw or hand held brush cutter is to spray the stump within 20 minutes with 41% glyphosate mixed 50-50 with water. It kills the stump forever.

Using a surfactant can help a lot, that is if whatever you pick doesn't already have it added. If it includes a surfactant then don't add anymore. Surfactants break the surface tension of water/herbicide basically allowing the mixture to "stick" to the plants.

What kinda brush ? Max rate on lv6 will knock the crap out of it with some mso to make it stick

I use the generic stuff tsc or royal king sells half the price of name brand stuff and honestly I cant tell a difference

If you are cutting and treating the stump, then Tordon works great or a product called Pathway.

I use Ortho ground clear.
Had it on hand for a few years.
Pour it in a cup, paint brush the stump.
If there is new growth, clip it off and paint it again.
This was the only way I could kill an old willow tree in my septic field.

George, isnt 24d a brush killer and not a fine leaf (grass) killer?

IIRC its a broadleaf killer???? The diesel will however kill the grass.. Roundup is a fine leaf or grass killer.

I'd be the whole summer painting all the stumps of the bushes I cut.

(quoted from post at 06:29:21 06/15/21) I'd be the whole summer painting all the stumps of the bushes I cut.

Phil, you have to put it on full strength so a 32 oz. spray bottle, which is how I do it may work. It would be far faster than brushing. Note the instructions for how soon after cutting that it must be applied.

Years back I hired this outfit with 2 bobcats to clear a pasture. One had a brush bucket with thumb for stacking. The other one had a horizontal saw blade on the front with a spray attachment on top. He would move in and cut the tree and as he backed up he hit the spray button to spray the stump with Tordon which is what he said they used.

I really like this one for hard to kill woody plants.

fixerupper · Jun 16, 2021

Like some of the others I use a generic farm store brush killer and add some surfactant. You have to get every leaf wet. Some trees like maples kill easy. Mulberry with its shiny leaves is hard to kill.

Brushtox with Triclopyr.

Patrick Wood · Jun 17, 2021

I have crossbow

Might have to use hand pump for diesel

To dry here, Taylor County , WI, to spray w/diesel and light.
no rain since mid may , may 1/4 inch

not to highjack this thread but I'm looking for a brush/weed killer to get rid of pecan and oak seedlings in natural areas in my yard...mulching over the years and lots of oak trees dropping acorns and I imagine the mulch had pecan shells/nuts built in. I also have mature george tabor azaleas in the same beds and don't want to damage them..

Pump sprayer will be used with spray on each individual seedling if necessary and avoiding azalea areas...

suggestions ?? Round up doesn't touch these. might even make them grow more

thanks
john

I know tordon with a surfactant will kill cedars up to about 4' tall. Didn't know how much surfactant to use on that first tank, it hit the pump and the pump lost about half speed. 2 weeks later, brown cedars.

When I cut a tree, I put a couple slices in the stump so it can pool and be sure to be pulled into the stump.

Even worked on a stump that was cut off above the barb wire fence it grew around. Drilled a couple holes down lower and filled them, too.
