Other than chemicals, the only thing that has worked for me is
persistence with pruners. The roots can't survive without
photosynthesis, take away the leaves constantly and consistently and
the roots will starve to death.

My suggestion is roundup concentrate.
Pour it FULL strength on the tree, [snip]

NEVER use a concentrate "full strength". It's a "concentrate" for a
reason.
It needs to be mixed with water to be safe, and to be effective.

The bottle of roundup concentrate has instructions for using it full
strength.

I'd try painting it on the new growth full strength..willow's are tuff
stuff.
