The influence of liquid properties on spray atomization and deposition characteristics was studied using two oils of different viscosities and volatilities. For a given volume of oil sprayed, insecticide diluent 585 (ID 585), a petroleum distillate of low viscosity and high volatility, provided numerous small droplets on Kromekote® cards. However, volume of oil deposited was low. For the same volume of oil sprayed, Sun-spray® 6N, a non-volatile paraffinic oil of high viscosity provided fewer but larger droplets, and consequently, the volume of oil deposited was much higher on the cards. These observations are explained on the basis of viscosities and volatilities of the two oils.
