Among green peach aphids that are in contact with a 2% soap solution, around 95% of the adults and 98% of nymphs die within 48 hours. [15] At 0.75% concentration, the mortality rates are reduced to 75% and 90%, respectively. Since 2011, insecticidal soap has also been approved in the United States for use against powdery mildew.
The quantities vary depending on the source, but a common concentrate typical mixture is 4 parts of vegetable oil (a non-mineral oil) to one part of liquid dish-washing soap/detergent (for washing by hand).

To ensure that application rates do not exceed limits which may be toxic to non-target vertebrates, the US proposes a maximum application rate of 0.1 to 0.6 pounds per acre (0.11 to 0.67 kg/ha) of active ingredient per season of agricultural land, differentiating between different crop types. [14]
