ISTR that some time ago the chemical composition of Jeyes was changed
because of some EU war on chemicals and became less effective on
things like moss.

In any event, it's no longer sold as a soil sterilant. AFAIK it hasn't
been banned as such by the Eurocraps but it's a case that the
manufacturers didn't want to fork out for the necessary licences and
so can't market it for that purpose.

So it wasn't changed or was it?

I believe Jeyes used to contain tar acids which were banned by the EU
so there was a formula change.

Separate from that, there was some licensing requirement relating to
sale for certain purposes and manufacturers opted not to pay (not sure
whether they wouldn't fork out for retesting or annual licence costs
or both).

I think it must be weaker than it used to be - read somewhere last
year that you'd need a 5:1 concentration in water to safely sterilise
containers in which you'd grown "diseased" impatiens. I find it next
to useless for removing algae from paving unless it's virtually neat.

I was sort of wrong about the formula issue - the tar acids and the
classes of use issue were linked (see Martin's later post) and I had
thought they were disconnected. There was, though, a composition
change between 2006 and 2008 - the data sheets for those two dates
show a reduction in the maximum percentage of tar acids from 15 to 10%

Your comments about it seeming to be more dilute these days are
consistent with a reduction in tar acids: they've just diluted it a
bit more to get within some regulation or other!
