DiPel PRO DF Biological Insecticide does not require the use of a surfactant. If you want to use one, it is important to use a product that is actually designed for this use such as the Southern Ag Non Ionic Surfactant. Dish soaps can be ionic and you can risk burning plants when used as they are not designed for this application.
