Abstract: A variety of devices that help to prevent drops of spayed pesticides from getting into places that are difficult to reach (e. g. under the leaves of cultural plants of on the stem), is offered. Special devices Lechler DroplegUL are designed in a way that nozzles that are embedded in the end of the spraying pipe which is bended backwards, spray diagonally upwards. Data of the quality of spraying fluid by using various sprinklers in special devices Lechler DroplegUL is provided in the article. Two hydraulic flood nozzles Lechler 684.356.30X, mounted in a special holder TwinSprayCap were examined: pneumohydraulic twin flat spray air-injector nozzle Lechler DF 120-03 and hydraulic twin flat spray nozzle Lechler DF 120-02. A transverse repartition and a process of the formation of fluid drops, sprayed using different nozzles were examined. The results revealed that while spraying with a lower working pressure (e.g. 1.5 bar) with two hydraulic flood nozzles Lechler 684.356.30X that are placed in a special holder TwinSprayCap and embedded on a device Lechler DroplegUL, a majority of drops (evenly around 40 ml) get into stand trays that are in a setting place situated 70 – 110 cm behind the device Lechler DroplegUL, whereas at the approximate 40 cm area away from the setting place there are no drops of sprayed fluid at all.Having the working pressure increased to 3 – 4 bar, majority of drops (around 60 ml) get into the stend trays that are in a setting place situated 70 – 110 cm behind the device Lechler DroplegUL. Having the working pressure increased, an unsprayed area, which is situated around the setting place of the device Lechler DroplegUL, gets narrowed: a width of unsprayed area when spraying at the pressure of 2 bar was around 60 cm, whereas when the pressure was 3 bar and 4 bar, the area appeared to be only 20 cm.[...]
