I have been clearing a thicket behind my home and have come across a plant that resembles a grape plant. The leaves are similar and it has a vine that grows both along the ground and up into bushes and trees. I have tried to kill it with weed killer and even full strength vegetation killer and it is still growing strong. So far the only thing that has worked is to cut the vines and pull it from trees and of of the ground. I am wearing gloves during the pruning and removal but I am getting a rash similar to poison ivy from this plant on my exposed arms and legs.
