Sprayer Tutorial

Sprayers are the most common pesticide application equipment. They are standard equipment for nearly every pesticide applicator and are used in every type of pest control operation. Sprayers range in size and complexity from simple, hand-held models to intricate machines weighing several tons.

Electrostatic Sprayers

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).

Advantages:

  • 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.

 

Limitation:

  • useful only for application to foliage.
