“…To spray pesticide in a confined area (Panneton et al, 2000) (Planas et al, 2002), a closed chamber with a metal top cover, pneumatic side walls, and a bottom surface consisting of soil or greenhouse bench covering was initially analyzed. Two atomizer nozzles were placed inside this chambers.…”

“…The physical transport of applied agrochemical sprays through the air to any off-target site is considered spray drift. Many factors affect drift including: (1) The effective composition and type of liquid preparations, droplet size and volatility; (2) Spraying equipment, use of technology, and aircraft operating parameters; (3) Meteorological conditions, such as wind speed and direction, temperature and humidity, atmospheric stability and terrain; (4) The operator's sense of responsibility and skill level [11][12][13][14] . To control weeds, pests and diseases, it needs optimal pesticide dose, the most suitable droplet size, and weather conditions, so that the droplets in the target surface can be better coverage, attachment, spread and absorption.…”

Spray drift has always been a focus research area in the field of unmanned aerial vehicle (UAV) application. Under the fixed premises of UAV operating parameters, such as height, speed and spraying liquid, the droplet drift is mainly affected by meteorological conditions. In this research, the spray drift and deposition tests were conducted using a QuanFeng120 UAV in a pineapple field under various different meteorological conditions. The experimental results showed that with the changes of UAV operating height and wind speed, the start position of the in-swath deposition area changed 4 m in the extreme situation. The percentage of the total spray drift was from 15.42% to 55.76%. The position of cumulative spray drift that accounted for 90% of the total spray drift was from 3.70 m to 46.50 m relative to the flight line. According to the downwind spray drift curve, the nonlinear equations of the same type under the four operating conditions of the UAV were fitted. The spray drift and the deposition of UAV application were significantly affected by different meteorological conditions and UAV operating heights. The results could provide a theoretical basis for UAV spraying in pineapple plants and support for spray drift control and prediction.

“…Consequently, lower spray volumes could be achieved without impairing spray deposition. Indirectly, nontarget contamination and spray drift can be reduced (Grinstein et al 1988;Hislop et al 1993;Knoche 1994;Panneton et al 2000). Droplet deposition on the underside of leaves is higher with the use of air-assisted sprayers compared to hollow-cone hydraulic nozzles (Holownicki et al 2000).…”

Florida strawberry production is greatly affected by Botrytis and anthracnose fruit rots (BFR and AFR), caused by Botrytis cinerea and Colletotrichum acutatum, respectively. Fungicide applications are the most effective method for control of both diseases. Traditionally, Florida strawberry growers use sprayers mounted with hydraulic nozzles delivering high flow rates. The objective of this study was to compare the standard hydraulic nozzle (SHN) sprayer with the air-assisted rotary atomizer (AARA). The effects of low volumes on the control of BFR and AFR, the reduction of 25% on fungicide rate, and their operational efficiency were evaluated, and an economic analysis was conducted. Two experiments were conducted (in the 2014-2015 and 2015-2016 seasons) where three treatments were compared: two using the AARA at 25 gal/acre, one of these with 75% of the fungicide rate; and one using the SHN at 100 gal/acre. In the first season, yield, AFR control, and BFR control were similar for all three treatments. In the second, BFR control was similar among all the treatments. However, the AARA treatment had a higher yield than the SHN, with the AARA (75% rate) being more productive. The operational capacity in acres per hour of the AARA was 17% higher than the SHN. Labor and fungicide costs were lower in the AARA treatments. Thus, the technology was shown to be a good fit for Florida growers. Accepted for publication 25 October 2016.
