A directed air-jet sprayer (SEPIA) was compared with a conventional radial flow sprayer (TERMIT) to determine possible control of spider mites (Tetranychus urticae Koch) and currant rust (Cronartium ribicola J. C. Fisher) on black currants when using spray volumes 260, 400 and 600 dm3 ha-1 and different dose rates of chemicals. The Cumulative Infestation Index (CII) for spider mite and percentage of infected leaves for currant rust were evaluated to determin the biological efficacy of applications. The spray deposition across the bushes and spray loss to the soil and to the air were assessed in order to compare the quality of treatments. The efficacy of pest and disease control was reduced for the lower chemical dose rates. Both the sprayers produced similar deposits within currant bushes, however, the directed air-jet sprayer caused considerably lower spray loss than did the conventional sprayer.
