This weed grows like crazy in upstate NY in Binghamton. Just how
widespread is this weed?

In our area, we call it Japanese Bamboo, our more commonly just
bamboo. It's so hard to get rid of it. It grows right back after
pulling or flattening. Did this plant overpopulate in Japan?

I took some neat pics of this weed.

A big piece of property wasted to knotweed.

Even after a mow, this pesky stuff grows back.

Why do you call it bamboo?
From your pictures I don't think it looks like bamboo at all.
Some dwarf bamboo varieties are invasive but they do not look remotely like
your stuff.
Do you know the scientific name thereof?

Fallopia japonica or Reynoutria japonica

A very fast spreading weed in central Europe too.

There seems to be a specialized biological control in its home country
(I think they may have identified a rust fungus) quite lacking in UK
and other infested areas. It's always called 'Japanese knotweed' in UK
vernacular; Collins Field Guide gives only 'Reynoutria japonica' as a
scientific name.
