When I worked on a market garden, I and the rest of the team used to spend
many a * happy * hour checking all the brassica leaves for Cabbage White
butterfly eggs. This was done on a regular basis and as we didn't use any
chemicals or sprays, we rubbed over the egg rafts with our thumbs.squashing
the eggs before any caterpillars hatched.
That job was on top of the other every day gardening work and we didn't get
any extra pay for doing it. Oh happy days!!!

I don't know what the active ingredient was, but I used to have some
spray on/water on powder that would kill off the massive caterpillar
attacks that denuded my brassicas. Does anyone know of a similar product?
