Summary:
Studies will be conducted to explore the applicability of using dispersion modeling coupled with real-time meteorological data to optimize spray swath widths. These studies are designed to measure uniformity of multiple spray swaths using conventional spray techniques and modified spray swaths as determined by the dispersion model for swath width optimization. The main sampling tool that will be used is a continuous monofilament line that has been laid across all of the swaths during each canopy test. After completing a replication, the monofilament line will be run through the USDA Monofilament String Analyzer, which continuously measures the amount of dye on the line to a 6 inch resolution. The amount of dye will be plotted against distance allowing a mean and coefficient of variance (COV) to be calculated from this data. Water sensitive cards will also be placed in the field during the testing to measure droplet size and deposition values. Cotton leaves will also be collected and analyzed for dye deposition. The studies are designed to evaluate the effectiveness of real-time swath optimization for agricultural aircraft.
