    Abstract

    Twelve direct drift comparisons were made from four atomizers using soybean oil and water as the spray carrier. Downwind drift deposits from the rotary atomizer and air-assist nozzles depended on operating conditions. The use of oil for application of chemicals provided little difference in drift reduction as compared to water. Oil has a nonevaporative character compared to water and so deposited higher amounts and drifted further downwind. With conventional twin-orifice and flat fan nozzles oil drifted further downwind than water. Comparing nozzle types, low volume applicators showed more downwind drift than conventional nozzles.
