What is the best treatment to remove moss from a fairly old rough tarmac

thats for fungus, not moss.

It's for neither. It lost its approval for use as a fungicide 17 years
ago! It can still be used as a disinfectant, and if it got spilt by
accident on some fungus or other...

In days of yore, wasn't armillatox the same as Jeyes fluid but just
under a different name for marketing purposes?


While some products have been re-formulated over the past decade or so
it may be that the manufactures are no longer able to claim their
product is for certain usages.

From the Jeyes Fluid FAQ or product description

Regrettably, as this product is now subject to Ministry regulations, we
are unable at present, to confirm recommendations other than those
printed on the latest can.

Since EC Regulations in 2003, the product is no longer effective at
sterilising soil.

Since EC Regulations in 2003, the product is no longer effective as a
winter wash.

Since EC Regulations in 2003, the product is no longer effective against
black spot.

Since EC Regulations in 2003, the product is no longer effective at
killing moss, nor will it be effective at preventing moss re-growth.


Well, I did say in days of yore, by which I meant in the later decades
of the last century. I think that in the past it contained tar
distillates (phenols and cresols) that were deemed to be carcinogenic,
which since 2003 have been removed and the whole thing re-formulated,
a bit like creosote. It was those tar distillates that made it
effective!


I think that it's similar to many things these days - just a dilute
detergent. In other words, no longer effective at almost anything! Other
than cleaning, of course. :-)
