Ive been battling AO on my farm in SE Ohio for a little while now. Some is so bad that I am going to bring in equipment to remove it. Heres a couple things I have had luck with though. 20% Tryclopyr 4 mixed with diesel. The beauty to this mix is you can do cut stump treatment, basal bark treatment with the same mix. Also, it will kill Ailanthus deader than a door nail with basal bark treatment. One mix, covers lots of different things. Also, mowing works really well with one VERY important caveat…..you are diligent about going back as soon as the stump sprouts come up and spray them. Foliar spray application with something like crossbow works well on these and they are pretty easy to deal with because they are small. This is not a method for those that might forget about going back for a couple years unless you enjoy being miserable lol. My place will never be eradicated of it but im doing my best to reclaim some land back and keep it from taking everything over.
Great feedback Chad, appreciate you taking the time to share your experience. I found this Crossbow and diesel also did a great job on the Ailanthus. I don't have a ton of it, but it is popping up here and there. Saw more chinese barberry than ever before... i guess it helps to know what everything looks like while you are out there hiking with a sprayer. haha. We are of the same belief... we will never eradicate it, but we have seen huge benefits already where we cut back AO that was choking the forest edges... huge improvements in browse for the deer. - Josh
Did you meet with Mark from the ODNR? This treatment has been very successful. I’m working on a very heavy section already this year and have already gone thru a 3 gallon mixture. Good luck!
Hey Rich; sorry I missed your comment. I’ll have to check out Pentra, I hadn’t heard of that. My treatment worked very well and was a lot less work and more effective than the cut stump I did last year. Thanks for watching and commenting. - Josh
hey josh, the part I don't like about treating tall plants is that after they die they are still there and standing which makes the area more difficult to manage future treatments as well as becoming another fire hazard of standing dead material that needs to be cut or mowed. So I started mowing anything under 2" diameter before I sprayed them and waiting for the resprouts to treat. The mowing mulches up the standing material so it doesn't have to be chipped or hauled off. Overall it just leaves a cleaner area that makes finding new plants and resprouts easier to see and find. Fighting your way through tall dead standing sticks to find new sprouts that are coming in is difficult. The bigger plants over 2" diameter you still have to cut with a saw and lop or chip whatever you do with the material but if your management is consistent then they don't get that big.
Mike, apologies for the delayed reply as I've been contemplating your feedback and have recently had a bit of an update to my understanding after running a chipper in North Florida. For me most of the stuff I've been treating has been deep in the woods on very hilly terrain so hauling a tractor and chipper in is impractical, but the stuff around the edges may not be too bad. The first year I carried loppers and a pole saw and cut everything before treating and it wore me out. The basal treatments are much more effective and I've actually had less resprouting than I did with cutting for some reason. What is really interesting is 6 months after treating you can walk up and knock over this bushes and they just crumble... all that said, it does not help with fire control for sure. Our woods are litered with debris that would make fire control terribly difficult so I've never made that a focus. We are mowing stuff out in the fields but man I just see if proliferate afterwards, instead of a few stems off the trunk there are 20... We will see how that goes as Jason just paid to have over 5 acres mulched with a fecon mulcher and it looks amazing but I think its going to explode with new trees due to the seed bed. Time will tell. overall we are catching up with many many years of neglect on this land so what we are doing is definitely putting a dent in it, but we have a long ways to go. Thanks for watching and taking the time to share in your insights, they are much appreciated! - Josh
Steep terrain makes everything difficult and you kind of have to do whatever you need to do. You may want to check out a walk behind brush mower though. I have two that we use that can cut 2" diameter saplings fairing easily. Then we just run over the cuttings a couple times leaving the area free of standing deadwood. We come back and spray the regrowth in the spring or whenever. Not having the standing dead material makes the area more accessible and easier to see any new shoots coming in
I’m in IL, Russian and autumn olive everywhere, not to mention honeysuckle. It has taken me 10 years and I finally have it controlled. All 3 species require spraying seed sprouts (birds) EVERY YEAR. I cut all larger plants and spray the cut stump with 25%triclopyr/75%diesel. For smaller sapling, spray the plant. It doesn’t take much but coat the leaves. Basal bark is probably only about 75% effective and leaving behind 25% is unacceptable given the dangerous and toxic labor. I wear gloves and eye wear, though a mask may be warranted. With large stands like you have, I would get a Vail brush grinder on a skid steer with 2 people spraying behind you. This will yield 95% results.
All great points! It is a constant battle but we are seeing good results but have many more to go. We’ve discuss getting a mulcher in for a day or two. Definitely a big job but the results are worth it. Thanks for sharing your tips and experience!
Appreciate this video! I'm in SE Ohio also, and we are inundated with these olive trees (Russian & Autumn), and have been using a 20% Remedy 80% diesel mix with virtually 100% success. Small trees (up to about 2 inch diameter) are lopped off and the ends are sprayed. Basal bark on everything thing else that can't be brush hogged. With the really huge trees (up to about 8 inch diameter), I basal bark and then spray along some of the larger branches. I'm scared to death to try any other mixture, considering the work and time needed to possibly go back and respray, but I'm alwys looking for something less expensive.
Thanks! I'd say go with what works... I think this will be a project that never ends but I don't mind getting out and hiking the property. Maintaining it should be easier than these initial years but man is it everywhere. I was told that the logging company likely brought in some invasives with them based on the young tree of heaven I have... I was told by the DNR forester that its not uncommon for the equipment to go from project to project without any sort of efforts to remove seeds...
I’ve not tried on bush honeysuckle as luckily we have very little of it. In terms of foliar spraying the USDA folks advised against spraying anything above waist high to prevent drift. I think this mix would kill about anything but have only used on autumn olive, tree of heaven and barberry.
I think your understanding of ratios is off. I just treated about 2 acres of olive on my buddy's farm. According to what our consultant told us is that it's a 4:1 ratio. In other words, if you use 4 gallons of diesel, your triclopyr should be 1 gallon. Based on that ratio, we used 1 gallon of diesel and 1 quart of Remedy, which is 60-some percent triclopyr. We just cut and sprayed, "hack and squirt," or foliar sprayed our olive. I'm interested to see the results. This was in Athens county, Ohio, 8/14/22
Hey Chris, I can’t speak to triclopyr on its own but I’m using Crossbow which has 2,4D and triclopyr and the mix rate for basal treatment calls for 4 gallons crossbow to make 100 gallons with diesel or kerosene. I have had great success on over 50 acres at a rate of 3 gallons diesel to 12-16 ounces of crossbow. Minimal resprout and significant progress. We are on the Athens/Hocking border. I would assume at that mix rate you will have very good success. Here is one of the links that points to the ratio and it’s also in the Crossbow instructions. efotg.sc.egov.usda.gov/references/Agency/WV/Archived_Brushherbicides-2003_160705.pdf
This particular time I did not use oil based dye and I learned that it did not work... essentially the water based dye separated and came out first ahead of the herbicide and diesel. We have since bought some Bas-oil blue dye but I've not yet used it.
It actually worked very well. I just walked the woods with my DNR forester for the EQIP contract approval and I could walk up to the dead autumn olive and swipe my foot and they would fall over. Completely dead. I did find a few that have some regrowing but overall this was much faster than cut stump approach.
That's definitely a good thing... They are everywhere on the property as well as all along roadways... here in Ohio once you know what to look for its a bit concerning to see just how invasive they have become.

Awesome video! We just met with the county forester 2 days ago who recommended this treatment. Thanks for clarifying its usage. We are in SE Ohio too
Did you meet with Mark from the ODNR? This treatment has been very successful. I’m working on a very heavy section already this year and have already gone thru a 3 gallon mixture. Good luck!
Crossbow and diesel seems to work great. You will definitely have to keep going back and respray. Great job.
Thanks, I'm hoping it works well. Looking at them today about a week later and they have wilted... so curious to see how long they take to die.
I started out using Diesel for basal bark treatments and now use PENTRA BARK. Thanks for the video, I'm working on Russian Olive here in Wisconsin.
Hey Rich; sorry I missed your comment. I’ll have to check out Pentra, I hadn’t heard of that. My treatment worked very well and was a lot less work and more effective than the cut stump I did last year. Thanks for watching and commenting. - Josh
Have been using basal bark treatment with 1 pt triclopyr/3 pts diesel year round. Had pretty good success especially spraying fall through winter
Glad to hear it! Mine turned out great and hit the woods for 3 hrs last week and am headed out now to attack some more invasives.
Keep after the AO!! Love it!
Thanks Al! Progress...

Triclopyr mixes real nice with bar oil....
Good to know. Will have to give that a try.
Might be a good way to get rid of some used tractor oil, I got lots of that.
Another Athens invasives battler here. What about foliar spraying? Have you tried this mix on Bush Honeysuckle?
I’ve not tried on bush honeysuckle as luckily we have very little of it. In terms of foliar spraying the USDA folks advised against spraying anything above waist high to prevent drift. I think this mix would kill about anything but have only used on autumn olive, tree of heaven and barberry.

That first year regrowth utilizes the roots from the year before- next year mighta oughta coulda shoulda be vastly restricted regrowth
I sure hope so... the good news is I’d say the resprout rate was about 25% of all sprayed. That’s my hope anyway...
Did you use Bas-oil blue dye? Was it an oil solvent dye?
This particular time I did not use oil based dye and I learned that it did not work... essentially the water based dye separated and came out first ahead of the herbicide and diesel. We have since bought some Bas-oil blue dye but I've not yet used it.
Josh, how did this work out? Did it completely kill?
It actually worked very well. I just walked the woods with my DNR forester for the EQIP contract approval and I could walk up to the dead autumn olive and swipe my foot and they would fall over. Completely dead. I did find a few that have some regrowing but overall this was much faster than cut stump approach.
We don’t have autumn olives around us.
That's definitely a good thing... They are everywhere on the property as well as all along roadways... here in Ohio once you know what to look for its a bit concerning to see just how invasive they have become.
