    Water repellent adjuvants increase the surface tension in contrast to surfactants that decrease surface tension of spray solutions. Increasing the surface tension spray droplets could potentially bounce through the plant foliage and canopy to target sites below. In this study organosilicone water repellents were applied with the herbicide, flumioxazin, and the insecticides, permethrin and carbaryl in greenhouse trials. Foliar retention was determined with the addition of Chicago sky blue dye which could be measured spectrophotometrically. Only the inclusion of DC1-6184 consistently reduced foliar retention of the various spray solutions on the spectrum of test plants.
