Summary. A small-plot logarithmic sprayer, similar to that described by Cialone & Bayer (1962) but using containers more easily obtainable, and operating frorn a compressed-air source, has been designed. Its main properties are portability, ease of operating and cleaning, and low cost, both initially and in future maintenance. It is of considerable value in difficult terrain, or when only small samples of chemical are available.No mechanical agitation has been provided. It has been found that even with wettable powder suspensions, the hydraulic force of the diluent entering the concentrate bottle is sufficient to provide adequate agitation when using bottles no larger than 200 ml.Replacement bottles are readily available, almost all over the world. They are of the type sold containing proprietary beverages under pressure, the essential feature being the crown-cap.Theoretical and actual dosage curves are very similar, and the machine has proved very useful for investigating dosage response characteristics of herbicides over the past season.
