The message
from Pam Moore contains these words:

No - it was widely aired on GQT three or four years ago, and AFAIK
hasn't either been dumped or used.

I think what they said was that they could not recommend it for use
but what you did in your own garden was entirely up to you! (and that
applies to a lot of things!)

I think they were rather more caustic than that, but it was Armatillox,
Jeyes Fluid and other preparations which couldn't be used in the usual
way - or which couldn't claim to be effective unless expensively tested
- which carried that caveat.

As I remember it, the rhubarb juice was just said to be illegal to use,
and traces of scorn could be detected in the wording...
