Electrostatic sprayer systems give the pesticide a positive electric charge as it leaves the nozzles. Plants naturally have a negative charge, so the positively charged pesticide is attracted to the plants. The spray is directed horizontally through or above the crop (depending on the pesticide being applied).
- pesticide adheres to foliage well, so less pesticide is needed per acre,
- coverage is more even than with other types of equipment,
- minimizes the likelihood of drift.
- useful only for application to foliage.
