Anyone had any experience of this stuff?

Pure bollux. Any soap or wetting agent will distress white and black
fly. Soft soap is the most popular choice - collateral damage can occur
with some plants. I'd suggest buying a different gardening magazine....

In the interests of name and shame would you care to divulge which one?
