It looks suspiciously close to the fence. Worth looking over it to see if has spread from next door. If so, they are liable to have it treated on their insurance.
Just whatever you do, don't dig or pull it up as it will only make matters worse!
It is overhyped and I have come face to face with it. Knotweed is a pussy! Kick its puny a** with a hard core dose, and if it comes back, kick it again. You'll know you're winning if it looks more puny and fragile each year. If you're happy to play the long game (8 yrs plus) you'll eventually win.
Silver surfer is right. Use the recommended dose for tackling the knotweed. Too much or too little a dose will only prolongue the situation, much to your detriment if you own the property.
Roundup do a tree and stump killer with a pipette that is specifically designed to treat JK.
My suggestion would be to follow Silver's advice, buy 5 litres of Gallup 490 or Roundup 480 from Amazon and also a knotweed injector from there too (costs around £85). Inject a neat solution into the walls of the stems (videos on YouTube on how to do it) and the stems will die off very quickly. The sooner it is treated the better!
It will likely return for at least a couple of years but far less vigourously.
A friend had a big clump of JKW in the garden of the house she bought back in the '70s - she erected a chicken run around it and kept half a dozen or so sturdy chickens ... after about ten years there was no sign of the knotweed and nearly forty years on there's still no sign of it ... and she got eggs!

When using Round Up please do not be tempted to put it on as a stronger solution.
Follow the manufacturers instructions to the letter.
We inherited knot weed and with Round up managed to eradicate it completely in just a couple of years.
...but that was years ago.
Maybe now knot weed is resistant ...
We used the Round Up sold to to farmers in large concentrated bottles.
Not tiny spray bottles with it already diluted.
Maybe the chemicals aren't as powerful for amateur gardeners.
