Aphids and soapy spray
In article , "Cat(h)" writes: | | Interesting link, thanks Des.

The reason that they don't mention it is that our Lords and Masters in Whitehall have made it illegal to use detergent and methylated spirits, and imposed extra restrictions on horticultural soaps (such as Savona). A conspiracy theorist would suspect that was done in arrangement with the agrichemical companies. Regards, Nick Maclaren. |
