Honey Locust control

Well I’ve been spraying Honey Locust and Osage Orange sprouts in the pastures like crazy this year I’ve gone through about 600 gallons of spot spray for foliar application this year. I use 2 quarts of Remedy Ultra and 16 oz of Milestone and 1 quart of surfactant per 100 gallons of water. I find this to be very effective on both tree species. I also use a 10% Milestone and water mix for hack and squirt of honey locust. On Osage Orange a 20-25% a solution of Remedy ultra and diesel fuel mix is a very effective basal spray but not terribly effective on honey locust. I’ve read that a 5% mix of Milestone and surfactant is a very effective basal spray on the locust but haven’t tried it yet. I just picked up a 2.5 gallon jug of Dyna-amic surfactant from Helena Agri services to give it a try this fall the article I read used this particular surfactant with great success so I choose to use it also. Now I did use my 10% Milestone and water mix as a basal spray on a few smaller Locust trees no bigger that about 4-5” with good success so I’m thinking I may try a 10% Milestone to 50/50 mix of surfactant and water as the carrier to stretch the surfactant it runs $50 a gallon. These two tree species are troublesome so I thought I’d share some control methods I know to be effective on them. I’ve read a great deal about the control of these two and there is lot of bad info floating around the web concerning locust control in particular.

Good info.
I've also had a lot of luck using Crossbow on locust trees, I spot spray the small ones, hack and squirt or stump spray big ones. I don't spray near the area you are, I'm just using a hand sprayer.
Around here deer, coon and everything seem to eat the hell out of the pods then must crap seeds spreading those damn trees everywhere.

Is there a better time of year to do it? I'd assume december january kind of thing as the sap is heading to the roots? I've done it in February or so and all it does is upset htem and they come back stronger.

They are..........of the devil........

I get after them in spring and summer.

I foilar spray after full leaf out until about the end of July or earlier if we are in a drought condition. For hack and squirt and basal I feel the best time of year is fall when the sap is dropping into the roots but have done it with success anytime of year except spring. I simply haven’t even bothered during early spring. During spring I’m spraying Chaparral 4 oz per 100 gallons on Buckbrush, multi floral rose and blackberry during bloom.

Here are a couple good links for control of locust.

I've been taking out some black locust which is a relative of honey locust. I foliar sprayed 15% glyphosate and got a good kill. A 50/50 water/gly mix on cut stump in the winter did not work and has led to lots of stump sprouting. I wanted to limit use of triclophyr around a pond, so I only use that on the somewhat larger ones I cut stump. P.S. the gly mix does not kill osage orange stumps, so I use triclophyr on that.

I basal spray mine in early fall when sap is going down
