I would have to agree with a controled burn. I burned about 1000ft of barbed wire this past winter. It was a lot of fun. But of course I didnt have woods on either side it was pastures on both sides. I used my old gas tank that I no longer use for gas and filled them up with water. I also brought out shovels and rakes. On a very light windy day, I poured the water along an invisible line along the fence about 2ft from it. I would do this every 30ft or so and then set the stuff under the wire on fire. Worked like a champ. On the stuff that I thought that wouldnt burn, I put some old hay on it to give it a little fuel. Fence was covered with briar and woody wgetation, but its clear now. Just some small pine trees that didnt quit get the full treatment. Will use machete on those.

Just get yourself a Ghille suit, and walk near it and it will all be stuck on the Ghille suit and then take the suit off and burn it.

I think that a few Goats would be pretty easy..

goats goats and more goats!!!

remedy/grazon/surf king i have killed a ton of them in fence lines .you might need to treat the area more than once it just depends on how thick they are good luck.

heavy amount of remedy,grazon or 2-4d should do it. watch out where you spray because you could kill you other trees.

I always use remedy better mix it right though if its too strong it won't kill them like you want but it will definitely do the trick
