Poison Ivy

Hi.  For Mother’s Day this year I requested that we all work on garden/landscaping in our backyard.  Little did we know that poison ivy was hiding in the weeds!  Less than 48 hours later we all had it.  Needless to say, this has completely halted our backyard renovation.  How do we kill the poison ivy without touching it? Is there a spray that will kill it without killing the surrounding plants?
