OT — Locust tree war!

Can someone tell me what to get to kill these dang locust trees?

I cut the big trees down this fall, killed the stump with Tardon RTU and diesel but now I'm getting sprouts from the roots popping up everywhere.


I saw some 2, 4, D in the tractor supply this weekend but it said I need a license to buy it.

I don't want anything that will contaminate the ground considering I have new trees I've just planted last fall around all the locust sprouts.

This is the little place we're going to move to someday. I'm taking out the mesquite, locust and bodark and planting oaks, pine and other "nice" trees.

I'm all ears!
 
You do know when you cut on of them down and a thorn goes in the ground and brakes off it is the start of a new tree don't you??? They are one of the hardest trees to get rid of short of spraying the whole field and with what I do not know
 
'don't know, but you may have already contaminated the soil by using Tordon. I once gave each of the Canadian Thistles in my grove of trees just a little shot of Tordon and 20 foot tall trees around them died - dead! And, there weren't that many thistles. I was sick!
Maybe the RU is different?
 
I'm surprised that the Tordon did not kill everything IF you applied it to the stump immediately after cutting the tree. Later application is MUCH less effective.

That said, they will sprout from the roots for up to ten years but can be easily controlled by routine mowing. The more often the new shoots are mowed, the sooner the roots will die.

Dave........didja know, even though ya killed the stump with Tardon RTU and diesel, you did NOT kill the ROOTS and they will pop-up sucker sprouts. What you gotta do is clippie each sprout next to the ground and PAINT the sprout with weed killer of choice. You do NOT haffta spray the ground, just paint the top of the stub (I gitta cheap foam paint brush) and the natural tree action of pumping the tree water will suck the poison down into the root and kill it. ........Dell
 
I have them in a corner of one field regular mowing keeps them from getting worse but has not killed them. I did succeed in knocking them back substantially by spraying them with Ortho Brush killer.
 
I am watching the answers you get real close. I have had the same problem with Osage orange or hedge trees. We had a big ice storm in 07 that broke them all down and pulled some of them over pulling the roots and all out of the ground. Since then they have sprouted up all over my woods. Most of them in spots that I cant mow. I painted the stumps just like you did and that kills the stump but man they shoot up all around it. I have wondered if doing a controled burn of the area would have any effect on them. Dont want to damage the good trees.{dog woods and oaks} I sure get sick and tired of all the flat tires and the worst is running one of those blasted thorns through your boot. Hurts for days.
 
spray the shoots with Crosbow (spelling). Has worked for me. Crosbow/Tordon mix with diesel fuel spraying the trunks of larger trees will kill the hole tree.
 
Is there a time of the year that is better than another to do this. Would like to avoid the ticks and chiggers but I would sure love to kill of those thorn trees.
 
I'm watching the answers too. Mulberry trees (or Mulberry WEEDS) are the culprits I'm constantly fighting. Used to use 2-4-5T and diesel fuel sprayed on the lower trunk. Didn't kill them right away but they didn't wake up the next spring. A few weeks ago I tried that trick with 50-50 diesel and 2-4D. It's a long time till next spring. Jim
 
Just fence in the area, put in water tank and add longhorn cattle, Dorper and Shepland sheep and Boer goats. Final finish is with Duroc or Berkshire hogs- or local ferals. Couple years of this and the resulting barbecues, take big disk to level ground and plant whatever. Only partial tease- the use of goats and roughage eating sheep has been used in many places to control many plants- California example was on sloped ground that had brush fire hazards. Hogs will dig up sprouting trees- is the salad course with the grubs for them. RN
 
The Tordon can get into the root structure and spread and kill off roots for nearby. Mite want to try Round-up on the new growth.
 
You must have trees that are very susceptible. I have heard the warnings and therefore used Tordon very sparingly around trees. Haven't killed anything the last five years and have since become more bold. Still only spot treat and use a coarse spray rather than a mist.
 
been there done it,feel for you..trouble with spraying suckers is its hard to get enough on them to actually kill the root,so the just come out some where else.keeping them mowed is what ive had best luck with ,each time you mow you weaken the root because it needs the sun on leaves to survive.I did read a study somewhere that said if you fertilized heavy it would kill them,sort of like putting too much n on alfalfa?sad thing is most of them were planted around here,folks used them for fence posts.as long a people were farming the ground it kept them under control,but when they quit farming and would just went to cattle ,trees took over.maybe thats the answer,you may try plowing around them if you can. cutting up the roots and burying them might get them deep enough they cant sprout?I know we didnt have problems with them here until most folks quit using plows so much.
 
My old German grandpa said always cut your trees in the fall when the sap goes down and they will not come back.
 
That's the truth. I cut some mullberry saplings in amongst some pines. Put Tordon on the little Mullberry stumps. Killed the pines next to them. Mark
 
For locust, I use 1 1/2 ounce Brushmaster, 2 ounces Remedy, 1 quart diesel, 1 gallon water. Mix enough to thoroughly wet foliage & trunk. It kills the tree, then when sprouts come back from roots, I hit them with the same mix. After several rounds over a year or two they are just about to stop sprouting. Fewer & fewer.
 
Ya, I know 2-4D and water will just wrinkle the leaves for awhile. 2-4D and diesel fuel sprayed on the leaves makes every leaf it touches crispy but I have a feeling every leaf has to be covered, and that means the grass under the tree too. Maybe new shoots will come up, though. About 30 years ago I parked my sprayer under a mulberry and it killed the tree just from the fumes. Someone else did the same thing and had the same results. Jim
 
kill tree before cutting it down! works 100% of the time. if not; it shots new saplings from every root.
 
Eighty acres of my dirt in S.E. Nebraska, location may affect at least the timing of this practice. Anyway, this dirt has been in the family since 1867, when NE became the 37th state. My dad, 1904-1981, often said that his dad often said that; "If you want to kill a tree, cut it in August". Of course, cedars and other evergreens can be cut and will die whenever they are cut close to the ground. I am not adverse to using chemicals to stop regrowth after cutting trees but it is just a lot easier and cheaper not to. So, 3 or 4 years ago for a test, I cut the biggest (an 18 inch locust) on the place, in August, did not treat stump, there was no regrowth. My plan is to try this on dozens of small locusts next month. I believe dad thought that this worked because the sap was up in the tree, this time of year and needed to get back in the roots, in order for the tree to survive.
 
You guys are spending way too much money on brand names. Get some Trycopyr 4 form an ag store. Mix it 80% basal oil (crop oil if they dont have basal) and 20% Triclopyr 4. Girdle the tree with a machete (2" band of bark remmoved about 12" from root collar) and treat the band to the soil, all the way around. Be careful with that Tordon, we cant use it in FL anymore becuase of groundwater concerns and overuse.
 
Locust is a "Clone", and a grove of Locust is
all one big family, all interconnected. Cut one,
of a grove, down, and the clone puts up suckers!
 
I have no idea what basal oil or crop oil is? Where do I get that?


The killing the tree first makes sense and the August timeline makes sense. I want to get rigged up with some of this Trycopyr 4 and get after some next month. Go ahead and just finish off all of them on the property.

I've probably got another 20 locust at least and about 50 mesquite.
