Franz, where on earth do you still get Benlate?

I still have a few leftover sachets from some which I bought a
decade
ago.
When that runs out, I will start using a more up-to-date
fungicide.

You can say that again and again and again and ... :-)

Yes, indeed.
How does one know when a gardening chemical has passed its use-by
date?

Is there such a date with chemicals other than hormones? I'd have
thought that as long as they were kept dry, uncontaminated, and at
an
even low temperature most would be stable. Is that a misconception
in
the case of modern complex products?

Many of the complex organic molecules are not as stable as one might
wish for. Today I went to see my doctor about a fungicide for my
ears. He gave me a prescription with strict instructions not to use
it any more by the time it was 2 months old.
