Vine like plants have invaded my gardens. I believe them to be the "pale swallow-wort". Recently, after weeding the gardens, I developed a very itchy rash on my arms, forehead, face and chest (the rash on face and torso , I believe, is from wiping persperatioon with a towel, ut the worst of the rash is on my arms and is so itchy as to keep me from sleep. I've been fighting these insideous vines for about four years now and each year it gets worse. I pull yank and dig up each spring and during the summe but have had no success.
Is the pale swallow-wort toxic by skin contact?
Have any suggestion as tocontrol and/or eradication of this hated vine?
