After a lot of private mail, I think someone should redo: Using dishoap for aphid/whitefly control the recipie is: 1 TABLESPOON LIQUID DISHSOAP IN 1 GALLON OF WATER DO NOT USE new concentrated or antibacterial types. Anything to much stronger than that can leave you with some sick plants. for just aphids 1/2 tbsp per gal will also work. For you chemical gardeners, 1 tsp of Diazinon or Methoxychlor per gal is enough for aphids. Byron
