I am curious as to what your objection to tars is.  I have used black roofing goo for 
years, (cheap, easily found, easy to use), and never experienced any adverse 
effects.  We use peroleum-based products quite happily in the form of dormant oils; 
tars are just longer chain hydrocarbons than oils, but basically no more nor less 
"toxic", and the quanties used in grafting are markedly less than you would use in 
spraying dormant oil.  (In fairness, I have encountered this concern about tars many 
times before.  I just wonder whether there is any evidence behind it, or whether it is 
a "rural myth".)
