| Abstract:
Numerous reports indicate that a large portion of the applied argochemicals may be lost by misapplication, volatilization, runoff from leaf surface, and drift. These losses not only result in a substantial increase in the cost of pesticide application but also pollute air, water, soil, and food resources. Therefore, spray technology research at the University of Florida is focused on: a) characterization of spray droplet atomization, transport, and deposition on tree targets, b) evaluation of changes in equipment design and application techniques, c) effective application of pesticides under existing citrus production systems, and d) development of methodologies for rapid assessment of spray deposition. The objective of the paper is to briefly describe a few investigations that can lead toward improved spray coverage, reduced application costs, and minimum environmental contamination in orchard applications. Research results on droplet size, spray equipment, application parameters, and spray sensor are discussed in the paper. | |
