ABSTRACT:
Disclosed is a method and apparatus (10) for dispensing powdered pesticide (13). A housing (11) is separated into an upper chamber (12) and lower chamber (51) by a porous media layer (19). The powdered pesticide (13) is contained within the upper chamber (13) and is fluidized when compressed air enters the dispenser from air inlet line (18). The fluidized pesticide is dispensed through outlet line (34) and nozzle (36) when a control valve (50) is activated. Only particles having a size smaller than a predetermined size are dispensed; the remaining, relative large pesticide particles remain in the upper chamber until physically removed.
