My buddy at work suggested spraying gasoline on the plants. He said
this would dissolve the urushioil(sp?) and kill the plant. I am kind

I would consider this pretty poor advice. Regardless of the fire hazard
(which is considerable), one would have to be pretty darn precise with
the spraying to make sure there was no contamination of desirable
plantings or runoff onto the ground, which WILL kill soil biota and make
future plantings iffy at best. There are products registered for this
type of application - Roundup, Brush-be-Gone, Brush and Balckberry
Blocker, etc., if manual removal is too difficult. Home remedies like the
gasoline are frought with too many unfavorable side effects to be a
serious consideration.
