We have only found one and it stained our tanks... It was a red dye and frankly it didn't work out that well. The one I used in this video turned out to not be oil soluble and the dye left the tank first since it separated. You can check this product, maybe ask them for more details but I'm not certain it will do the job... www.forestry-suppliers.com/p/92996/87963/rrsi-elite-premier-blue-basal-oil-surfactant?stext=basal+oil+dye
Harm as in, can I kill them with it if I try or as in accidental harm? The diesel mix needs to be sprayed around the bark on all sides and it penetrates the cambium layer to kill the tree. Massive overspray could harm but not likely kill. There will be a dead spot on the ground around the target tree from overspray. The diesel is biodegradable after I think 80-90 days so doesn’t harm anything long term. This has been the most effective control method I’ve used and Ive tried a variety of approaches.
@@hardybrothersproductreviews Thanks for the response. I was asking about accidental harm, and it sounds like accidental overspray will not kill very large and mature trees in your experience. This is good to know. Thanks again!
How long did it take to start seeing the herbicide work? I did an equip contract using this same mixture. Been 2 or 3 weeks and have yet to see any progress. Worried that maybe my efforts and 28 gals of diesel fuel went to waste
hey Jordan, when i hit my stuff it was just leafing out and I too was disappointed to see that the leaves were just barely yellowing and wilting about 3 weeks later. That said, it turned out to be VERY effective... I am going to release a video in the coming weeks that shows me walking through in the fall and the skeleton plants and how they just break off, completely dead... I'd say 30-45 days and you should be able to see that it was effective. The ODNR forester that walked it with me in December was very pleased. When we found on that wasn't dead he would break off a branch and smell it... no diesel smell meant I completely missed it. I'm working my last area this year and went back to this method as it was so successful. Best of luck! Also we have more videos over on Hardy Brothers Outdoors... check out the Habitat Oasis Project playlist.
@@hardybrothersproductreviews What channel are you going to release that video on? Any idea on when the video will be available. I have heard that one of the issues when you spray in the spring with crossbow is that AO will look completely dead but the following spring, you will have a high number of new sprouts. Any experience with this? I recently foliar sprayed AO with 3% glyphosate. I will have to wait until next spring to know what kind of long term success I will have.
Hey Will, the next version will likely be on our ua-cam.com/users/hardybrothersoutdoors main channel. I've had some resprout but not much... in fact as i walked it in winter the AO was dead and could just be pushed over... I had quite a bit of resprout on my cut stump with glyphosate mixed at 50:50 water to gly, which is why I went to crossbow. Based on my current schedule it will likely be a month or so before I can get out shoot some updates. My advice is mix it a little stronger and get at it... my success rate was high enough I wouldn't think twice at treating in the spring.
I believe you are correct, 5.12 oz per gallon... Whatever I quoted has worked for me for two years straight but sorry for my math error... the bummer of UA-cam videos is you can't go back and fix them. Thanks for taking the time to reply.
Hi Dan, sorry your comment was held in a review folder and I am just seeing it now. We have had trouble with the oil based dyes since this video. Water based will separate and will be the first thing to leave the sprayer. This one we have used and it stained our sprayer and hoses - www.forestrydistributing.com/bas-oil-vegetation-management-spray-indicator-basf Honestly, I stopped using dye as the red wasn't that bright... it definitely makes it harder to keep track of what you have done as these autumn olive pop up randomly throughout the woods. Sorry that I don't have a better solution.
That is correct. Basal bark treatments penetrate the bark and the cambium layer and the plant is dead and brittle within 6-8 weeks. Check out this video I think it is more detailed as I had to cut this one down for Amazon. This one mentions some of the resources that you can learn more about. ua-cam.com/video/nw2ffStFZ0U/v-deo.html
You are correct… dang my math was off… I was heavy pouring 12-16 ounces but you are right. The mixture should be 5.3 ounces of crossbow per gallon of diesel. Thanks for pointing this out. The good news is my basal bark treatment was very effective even at 2-3% mixture rate. Thanks for the note! - Josh
@@hardybrothersproductreviews I just checked my fields and the 10 Oz per gallon I did last year worked awesome. Thanks for this video as I'm now starting to take back my fields from locust trees.
It is said that the berries can be a "super food" but I'm not finding a whole lot of people figuring out how to farm them and capitalize on them. I think the key with invasive plants is there is likely a better native alternative. So yes, while it can be okay, there is better. In our fields we are replacing them with native plants. In the woods is another story, they actually leaf out earliest in the Spring and keep their leaves latest in the fall, so they choke out the light to other things like hardwoods. My woods is under timber management plan for commercial timber, which reduces my taxes on my entire land by 70%. So the government program that subsidizes my invasives treatments is seeking to revive the oak tree population in Ohio forests. Hardwoods grow slow and when choked out by invasives are outcompeted by less valuable timber. It's amazing to see how many oaks are now reaching survivable sizes along my woodlines. Put simply, invasives overtake what was originally native to the area and reduce forest sustainability. Hope that helps...

I'm having a tough time finding a marking dye that says it's oil soluble. What dye do you use?

Does the Crossbow overspray harm the larger mature trees (10 inches and greater) like the ones behind you in this video?
Harm as in, can I kill them with it if I try or as in accidental harm? The diesel mix needs to be sprayed around the bark on all sides and it penetrates the cambium layer to kill the tree.

Try using garlon 4 at 25% (Active ingredient in crossbow) and 75% basal oil it is very effective at controlling Autumn olive
Isn’t a 4% solution 5 1/3 oz per gallon or 21.3 oz for 4 gallon?
I believe you are correct, 5.12 oz per gallon... Whatever I quoted has worked for me for two years straight but sorry for my math error... the bummer of UA-cam videos is you can't go back and fix them. Thanks for taking the time to reply.
Looked for link for the dye and don’t see it. Can you help me out

Tractor supply has it
You never had to cut anything just spray the pants?

You say 10 oz of crossbow for 4 gallons , but that’s only 2% percent not 4 % Shouldn’t it be like 20 oz?
You are correct… dang my math was off… I was heavy pouring 12-16 ounces but you are right. The mixture should be 5.3 ounces of crossbow per gallon of diesel. Thanks for pointing this out.

Just out of curiosity, although invasive what is wrong with Autumn Olive. It sounds like it can be useful.
