I think I have asked this on here before but what is the best thing to kill kudzu? I used Grazon last year and it definitely helped throughout the year what was still alive was very sickly. I probably should have followed up with a second round but never found the time. I sprayed roundup earlier this year and it roasted the dog fennels and other weeds but just yellowed the kudzu, now the kudzu has no competition and is taking off again.

I will eventually plant pine trees here so preferably something that does not have a residual that will harm pines.

Escort is what I use. It will not harm pine trees. even if directly sprayed. It is slow acting. It takes about a week before you can tell you spayed it and about 4 weeks before it looks dead. It must slow be to give it time to reach the roots instead
of just burning off the leaves. You will have to follow up treatments regardless of what you use

I've had pretty good success with the Ortho Max Poison Ivy & Tough Brush Killer. Got a bunch of it behind my house I have to keep in check.

Have killed it with roundup and it works ok but reapplication is a given. Disclaimer: my mix for this is very hot. Been a minute with Arsenal but think that is what I used that smoked the kudzu.

Tordon, tordon K.
I like to add imazapyr but don't use it if you want to save any young trees.

Tordon

I don't want to use any imazapyr if I don't have to. This is a sandy spot and if its bare it will wash pretty bad.

I actually have some generic escort that I may try this weekend.

I have used remedy ultra and things seem to die (triclopyr). It is expensive but I sure would listen to some of the other guys who have more experience with kudzu first. But in my limited kudzu battles it has done the job.

I have used this document before so I looked it up. Don't know how recent it is

Kudzu control

Tordon, its best with follow up application the next year.

Looked it up and it was Tordon that I used. Arsenal was for another project.

When we bought a house 4 years ago, one side of the rear yard was completely overgrown / out of control with English Ivy. There was a chain link fence bordered with 8 huge Leyland Cypress trees (for real, these trees are probably 18"+ diameter and 40' tall). That ivy had grown about 8-10 feet up those trees and over/through the fence into the neighboring yard. I bought some kind of stuff from the Co-op, cannot remember the name to save me, but I'd prob remember if you said it.... it might have been "Crossbow". Anyway, it had a MASSIVE strong chemical odor and left absolutely scorched earth. I was dumb and used a sprayer to spray all that ivy, not considering runoff or the affect on those cypress trees. There still isn't much grass within 10' of that old weedline, and as of today two of those cypress trees are 100% dead, and the remaining 6 are patchy dead. Granted, there was a terrible drought that year and I saw tons of old, large cypress trees die all around our community, but I have to wonder if it was really the weed killer.

Anyway, I 1000% guarantee you that Crossbow(?) stuff will kill it graveyard in days!!....along with everything else around. LOL

eraser kills everything around here never tried it on kudzu

If crossbow will kill hedge im sure it'll kill kudzu but never tried it on kudzu

Get a couple of goats, they will eat every piece of it right down to the ground.

Grazon Next HL, Milestone, or Tordon would be best before trees and then after pine is planted switch to Escort and just keep it best back until the trees get up enough to slow it down. I always try to treat kudzu two years in a row before trees go in the ground.

this

Yeah but then you have goats. I'd rather have kudzu.

Boil it like collards. Add some pepper jelly.

I have also used Crossbow. It worked but not as good as the Escort. It burned it up and it looked dead but did not kill the roots. same thing with glyphosate. It will scorch the leaves but come right back.
