My point of soap. I got flammed on another list for mentioning using dishsoap for aphids. A: The orignal soap was about the same as Fels Naptha Recommended in many OG books Pain in the butt to use B: Safers soap is a potassium based soap 4X the cost and 4x the amount needed as regular dish soap C: Regular dishsoap seems to be just as effective at 1/16th the cost.
