ABSTRACT:
An agricultural sprayer for injecting pesticide into an airstream being directed at foliage to protect the foliage from insects, vermin or the like. The air is generated using fans that pulls in air axially and directs the air outward in a radial direction. The radial outwardly directed air is then fed through a plurality of rotating vertically aligned elliptical paddles to create turbulence in the air. Pre-charged liquid pesticide droplets are then injected through a plurality of nozzles into a second airstream which directs the droplets into the outwardly directed air to regulate the droplet size. An oscillating sensor detects the foliage location and turns nozzles "off" and "on" to spray different foliage locations.
