No. 2. pp. 54-57. Interpretive Summary: As a new spray season approaches, understanding how nozzle type interacts with other operational parameters such as orifice size, spray pressure and airspeed to produce the droplet size being applied is critical to meeting pesticide product labels and ensuring efficacy while minimizing off-target movement. A review of these factors is provided, along with a demonstration of the tools developed to help applicators select the most appropriate nozzle setup for a given spray application. The spray droplet size models that are freely provided to aerial applicators will provide pilots guided decision making support when setting up their aircraft for the coming spray season.
