Maybe there are good reasons for banning some of these popular weed
killers, that have nothing to do with organics.

The reason for the ban is that in concentrated form if it gets in the
eyes it can cause permanent damage to the cornea.


There are many ordinary household chemicals used to unblock drains which do
the same thing, a lot more quickly, effectively, and _very_ permanently.
And they have come onto the market in the last few years!

The reason that most of these pesticides are banned is lack of information.
Many tests are required to show that they cause no, or minimal and
acceptable, harm, even if they have been on sale for years. Anecdotal
"proof" of harmlessness is not acceptable to the Regulatory Authorities; the
tests have to be done in a specific way, which is very expensive to perform.
The profit from older products (such as Rose Clear 3) will be less than it
costs to do these tests, so the manufacturers are caught, as our American
friends say "Between a rock and a hard place". That is the way most of
these products are forced off the market.
