Abstract: The application of insecticides and fungicides on the underside of leaves is performed with a help various technological solutions, seemingly as the application of soil herbicides and liquid mineral fertilizers that are sprayed under the leaves of cultural plants. This task is performed using straight spraying pipes with slit (symmetrical and asymmetrical flow) nozzles, stream conical flow nozzles, or specific curved (e.g.Lechler DroplegUL) nozzles that enable diagonal spraying upwards. The objective of the research was to identify the potato coverage differences spraying the biological product biokal1 with specific equipment Lechler DroplegUL for spraying the biological product under the leaves and various nozzles. In earlier stages of potato growth, the specific equipment Lechler DroplegUL and deflection nozzles Lechler FT 1.0 for spraying the product under the leaves of cultural plants better covers potato stems and the underside of upper leaves. In the control group, where the ultimate slit flat flow nozzles Hardi ISO F/LD-05-110 were used, droplets of the biological product covered 4.8±1.7 % of potato stem area only, the DroplegUL and three nozzles (LU-120-02 from the top and two deflection nozzles Lechler FT 1.0 from the bottom) covered even 55.8±39.1 %. Accordingly, plants of the control group had only 0.1±0.1 % of the underside area of the upper leaves covered with the product, while using DroplegUL and three nozzles such area reached 1.5±1.1 %. In later stages of potato growth, specific equipment Lechler DroplegUL with deflection nozzles Lechler FT 1.0 for spaying under the leaves of cultural plants better covered the underside of upper leaves of potatoes only. The usage of double flow nozzles Lechler DF-120-02 on DroplegUL and ultimate slit flat flow nozzles LU-120-02 on a spraying boom gave rather small differences in coverage of the surface compared the control group, where the ultimate slit flat flow nozzles Hardi ISO F/LD-05-110 were used
