Guess I would just interject that if you or neighbors inhale the burnt
poison ivy smoke they will be in for the worst case of poison ivy where
cala$ will not help.  I have also met people who try and burn sumac with
similar reaction.  Burning can volitilize the oils (much like smoking) and
can cause severe reperatory inflamation.  The only worse story I have ever
heard is the kid who ate some leaves of poison ivy cuz he heard that this
would protect him from ever getting it again.  Yes that was me..  I
subscribe to very judicious use of round-up on cut vine and only in high
use areas otherwise-----------------leaflets three let it be!!!
