Droplets of 95% malathion from a ULV aerosol generator were collected on silicone coated slides, using the "slide pendulum" and 4 hand waving techniques. The droplet distribution was characterized by calculating 7 parameters. These parameters were analyzed to determine the most consistent droplet distribution among the slide waving techniques examined. The vertical swing and "slide pendulum" samples taken 4 ft. from the nozzle showed the most consistent droplet distribution patterns. The vertically waved slides, taken at 25 ft., and the diagonally waved slides, taken at 8 ft., showed the least consistent droplet distribution patterns. In addition, the aerosol cloud was sampled at 3 vertical levels. The data suggest a relatively homogenous droplet distribution within the cloud, 4 ft. from the nozzle.
