OT-Question for Forestry guys... I have about a 20 acre cutover plot...

[The Usual Suspect]

in Oktibbeha county. It was hardwood timber that I cut a couple of years ago. Decided to let it come back on its own. I want to spray it next winter before Spring in certain places to try to keep the weeds/brush down. What herbicide should I spray that won't do any damage to trees, etc. Also want to spray along fence lines. Any recommendation is appreciated. Will likely be using ATV spray rig to apply.

Been a while since I did any of this but take a look at the label for Garlon and see if that’s what you need. You may also be able to spot spray with Polaris AC.
Fires can also be used in hardwood sites to control vegetation under the right condition. Call ms forestry commission or someone at the college of forest resources.

Oust and Alligare make a herbicide that can be sprayed in February while the hardwoods are dormant. Pretty much kills all the stuff you don't want. I planted a bunch of oaks last February and the Alligare worked well.
