Because of the unique characteristics of electrostatically-charged sprays, use of traditional methods has failed to accurately quantify deposition from these sprays. A new fluorescent imaging technique was developed that quantifies spray deposits from electrostatically-charged sprays on natural plant leaves. Results indicate that this technique can successfully detect and enumerate individual spray droplets on the underside of beet leaves. Further, this technique reveals the spatial distribution of the spray droplets. Researchers will be able to use this technique to quantify spray deposits on a multitude of artificial and natural deposition samplers.
