I have now purchased a specific ivy killer containing ammonium
sulphamate.

That's sulphate.


I wouldn't be so sure...

Oh! I'm sure I'm a scientist / chemist.
The yanks always spell things "let's say" differently to us British. It's
Sulphate.

You can apply ammonium sulphate to ivy and all it will do is make it
grow better - it's used as a fertiliser.

If you want to kill it you need ammonium sulphamate. Different chemical,
different properties.

(You also mentioned sodium chlorate ... similarly, it's important not to
confuse that with sodium chloride)
