Abstract
Abstract A method of producing an insecticide spray for killing insects with droplets in the size range of from about 5 microns to about 15 microns. The spray consists of an insecticide, such as Naled14, diluted with a non-volatile liquid, such as cottonseed oil, in a ratio of 1 to 4 by volume. The aerosol generating equipment includes an engine driven blower supplying air at about 450 cubic feet per minute at a pressure of about 4 psi. This air is supplied to a group of four air-liquid double vortical nozzles that atomizes the insecticide into the 5 to 15 micron size range.
