The apparatus consists essentially of a spinning disk which throws off liquid, applied to its centre, in the form of small droplets. These are of the same order of size (about 0.1–0.4 mm. diameter) as those produced by knapsack sprayers, but they are more uniform and consistent. The sprayer can be used to coat various surfaces, up to 1 ft. square, with deposits of insecticides in oil solution or in aqueous suspensions or emulsions. The deposits can be controlled and estimated with a fair degree of precision. Some rough samples of the spray clouds produced by a knapsack sprayer are recorded.
