An inductor nozzle assembly for use with an air blast sprayer of the type having a tank holding waterborne pesticides, delivery lines connected to the tank and an air blast fan mounted in close proximity to the delivery lines, includes a spray nozzle mounted to the delivery lines which is disposed in the hollow interior of a conical-shaped housing mounted thereto. The housing is formed with an enlarged entrance opening, and a reduced diameter discharge opening which mounts an inductor ring charged with high electrical potential. A high velocity stream of air produced by the air blast fan is directed into the housing through its entrance opening where the air stream is accelerated by the conical shape of the housing toward its discharge opening. The waterborne pesticide supplied to the spray nozzle is ejected through the discharge orifice of the spray nozzle in a finely divided particle stream which is directed into the reduced diameter discharge opening of the housing, charged inductively thereat by the inductor ring and then ejected from the discharge opening by the high velocity air stream produced by the air blast fan for deposition upon the trees of an orchard or other crops. The stream of air from the air blast fan which is accelerated within the housing forms a barrier between the atomized particle stream and the inductor ring to maintain the inductor ring dry and at its full electrical potential.
