A rotary disc device was developed for ground applications of ultra-low-volume (ULV) undiluted pesticides. The applicator consists of 2 rotating discs powered by a small electric motor and a metering nozzle. One applicator is used on each row. Experimental application of ULV azinphosmethyl (2 lb per gallon), applied to cotton with this device at 0.25 lb per acre gave boll weevil, Anthonomus grandis Boheman, control equivalent to standard methyl parathion applied as a water-emulsion spray at 0.5 lb per acre. Particle deposition within the plant and across the swath was compared with a mist blower ULV applicator. Both gave equivalent particle deposition within the plant, but the rotary disc device gave more uniform coverage across the swath.
