ABSTRACT:
A dry pesticide applicator is disclosed. The applicator includes a fluidizing medium secured within a housing. A blower mechanism generates a flow of air through the fluidizing medium to establish a fluidized bed within the housing. This fluidized bed is drawn into a dusting by means of a venturi to create a powdered stream. Whenever the dispensing mechanism is inoperative, the fluid flow which creates the powdered stream (by drawing the fluidized bed through a powder inlet) is directed into the housing through the powder inlet to purge any accumulation of powdered material therein.
