Abstract

Field studies with flatfan, twinjet, flood and rotary atomizers were conducted in 1987 and 1988. The results indicated that tridiphane at 0.6 kg ai/ha plus atrazine at 1.7 kg ai/ha with 2.0 L/ha of soybean oil adjuvant was more effective in controlling giant foxtail and common lambsquarters when applied by the flatfan, twinjet, and rotary atomizers. Image analysis indicated that weed control by a postemergence herbicide was generally enhanced by better application coverage. Droplet size measurement by phase droplet particle/droplet analyzer demonstrated that the rotary atomizer produced a narrower range of droplet diameters between the Dv.1 and Dv.9 volumes than any of the other atomizers.
