The distributions of coumaphos deposited on cattle by automatic mist sprayers and more conventional large volume power sprayers were determined by analyzing hair samples pulled from selected locations on treated animals. Wind and incorrect nozzle placement caused much of the variation in spray deposits left by automatic sprayers. Hair characteristics affected the spray deposits left by power sprayers. A linear correlation between the spray deposits from power sprayers and the weight of hair was positive and highly significant. The data indicated that automatic sprayers are capable of providing distributions as uniform as those provided by power sprayers.
