Technical Abstract: Spray droplets, discharged from the lower six nozzles of an airblast sprayer, were sampled on pairs of absorbent filter and water-sensitive papers at nine distances from sprayer. Spray deposition on filter targets were measured by fluorometry and spray distribution on WSP targets were assessed by three image analysis systems. Image analysis provided information on percent area coverage and several statistics on droplet size spectrum at various locations. This paper will discuss the relationship between spray deposition and distribution and the utility of WSP in quantifying spray deposition in low and high-volume applications.
