Cut it off and paint "Roundup" on the cut stems.
Kills it easy,

How does that work when it's only absorbed through the leaves?

No idea, it just works fine.

When the stem is cut, for a few seconds afterwards the sap is sucked
back down to the roots, so spraying with glyphosate during this
period ensures it is taken down as well, resulting in plant death.

I once had a Sasa bamboo that had got out of control, it must have had
more than 200 stems growing from the root ball. Cutting a few stems at
a time and immdiately spraying with glyphosate was almost totally
successful - only three tiny stems survived, which were easily dealt
with.
