Tom, please see my previous post-- read some Alex Shigo material.

Lee, latest research I saw on those hormonal anti-sprout treatments is they 
also
reduce the natural ability of the cut to seal/ heal.  I forget just how, or 
what
auxins & hormones are involved.  But these sprays are not recommended as much 
as a
proper pruning cut.  And ideally the cut is made when the branch is small 
enough
that resprouting to replace the lost branch isn't such an issue.
