Gly 4 Plus has killed everything I have sprayed it with including poison ivy, sumac, and oak around trees and really put a hurt on the briars, it did not kill the briars out but it stopped all growth and dried them up for a string weed-eater to take them out no problem.
Now I mix it stronger than the instructions, I buy it in the 2.5 gal jugs and mix 20 ounces of Gly 4 Plus with 15 gallons of water, which I think the instructions say 3/4 ounce per gallon.
Gly Star also seems to work however it takes twice as long for some reason to work and show results.

I add a little dish soap to it. Helps it cling to the vines better.

Oh really, thanks for the info how much would you add to 15 gallon?

I mix 5 gallons and put close to 2 tablespoons.
So close to 6

And I will be nice and tell you don't add it before you add the water.

6 Tablespoons I will try it next spray
LOL yea it would not be too smart to get all the foam and bubbles in the sprayer.

I have had good results with Element 3a. It will take out, briars, wood vine, and will actually take out smaller brush. It is also a broad leaf killer. It should not kill narrow leaf. I am not licensed to recommend chemicals, so read carefully. I mixed mine at 1oz per gallon, and its pricy
