Celsius WG Herbicide is not labeled for Catbrier also known as Greenbrier, Cat Sawbrier and Sarsaparilla vine. Greenbrier is a very difficult weed to control once established since it has a rhizome system under the ground.
This article from the UGA Extension service has advice on how to treat this plant:
For a glyphosate product, we would suggest Ranger Pro Concentrate and for a brush killer/triclopyr product, Crossbow Herbicide (triclopyr and 2,4-D) or Southern Ag Brush Killer (triclopyr) would be recommended.
