The paper presents the results of studies on spray nozzles, placed on a spray boom, hanging over a patternator. It was found out that when the location of particular nozzles is changed, the variation coefficient of distribution of the fall of the sprayed liquid (C.V.) changes as well. The change of C.V. is especially high for the nozzles which are technically worn out. The studies showed that while testing the nozzles on a patternator, the microclimate in the area of the site undergoes a change.
