Stephen, Interesting question.  We were told we can't provide information like this to clients for a mixture/product that does not contain a label.


That said, the proportion is 2-3 tablespoons of liquid oil, 2-3 tablespoons of liquid dishwashing detergent (not one that contains a degreaser which can burn the leaves of the plant) and 1 gallon of water.  (I always use Dawn regardless and it has not burned the leaves on my plants.)


Hope this helps.  Thanks.

Morning All:

Can someone advise on the proper proportions of soap and water for an insecticidal spray for aphids, etc. Is there a preferred soap for this purpose?
