Hello,

Bristly greenbrier (Smilax tamnoides) is the prickly vine that you have in your area. I’m attaching an article from Clemson University about the weed and how to control it. https://hgic.clemson.edu/factsheet/smilax-greenbrier/

The article suggests control by glyphosate.  Read about the use of glyphosate by water to assess it’s effectiveness and affect on wildlife. https://dnr.wi.gov/lakes/plants/factsheets/GlyphosateFactsheet.pdf

It refers to glyphosate only.  Many new products that are sold are not pure glyphosate but a combination of chemicals which may have detrimental effects on other vegetation nearby. 

Bristly greenbrier can be killed by spraying with a solution of vinegar but may take several applications. Vinegar will also kill other vegetation that it comes into contact with. Bristly greenbrier can also be removed by hand, wearing a pair of sturdy gloves. 

I hope this helps you with your weed.
