Technical Abstract: Aerial applicators are utilizing computer models and printed materials to comply with pesticide labels that specify droplet spectra, such as "apply as a MEDIUM spray." To help in the selection of the proper equipment selection for an application, studies were conducted to determine the spray deposition and drift from two "MEDIUM" nozzles used in an aerial application. The first nozzle (T1) generated three times more spray volume in droplets less than 200 µm than the second nozzle (T2). Droplets less than 200 µm are the droplets that are most likely to drift out of the targeted area because of their small size. The data showed very different downwind deposition occurs from the two aerial spray nozzles selected. T1 produced significantly higher downwind deposition than T2. At 50 m from the downwind edge of the spray swath, the deposition was 1.7% and 0.53% of the deposition at 0 m for T1 and T2, respectively. T1 also produced more airborne material at 50 m downwind of the spray swath edge than T2 at heights up to 10 m. These results were valid for spray applications made in crop canopies or over concrete runways. The results highlight the need for aerial applicators to consider all of the droplet spectra data when selecting the most appropriate spray nozzle for a given application situation.
