Abstract:	The choice of a proper nozzle for spray applications is of particular importance. The objective of drift reduction in viticulture is easily and substantially achieved with Air Injector Nozzles (ID). The biological performance of fungicides RGC, Flint, Folpan and Switch were investigated by comparing Air Injector (ID) and Hollow Cone Nozzles (TR). Results of the biological performance of the two nozzle types showed no significant differences for all fungicides applied. Deposits on leaves with the application of fine and coarse droplets by both TR and ID did not differ within the same sampling variant. Differences concerning coverage of the lower and upper leaves and the different zones of the vine did exist. Deposits on lower leaves were in general half as much as that on the upper leaves. In the bunch area of grapes, the coverage was slightly better than in the upper part of the vine. Droplet density on leaves was half as high for ID nozzles as for TR nozzles. Drift reducing Injector Nozzles are suitable for effective biological performance and coverage on leaves as well as for new fungicides. Environmental factors re lated to drift are taken into consideration.
