Aphids and soapy spray

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. Well, that's not exactly true. It's not permitted to use any preparation which isn't licensed and soapy water and meths etc. haven't been licensed. I doubt that one would be banged up for using such things but it is illegal to unlicensed sell soapy water as a treatment for pests. Mary |
