A variety of technical means are used to combat pest control. In this study, the operation of slit and diffuser sprays was observed in the coating of the lower and upper pepper leaves. When working with the slot spreader, the coverage of the entire leaf mass is significantly less. The sprayed working fluid does not have sufficient puncture force to penetrate the entire height of the plants. Leaf coverage averages 29% of the underside and 35% of the top. When using a diffuser sprayer, the air generated by the fan intensively stirs the leaf and forces the sprayed liquid with great force. This is a prerequisite for very good coverage of both the top of the leaves and the bottom. The coverage varies from 52 to 63% for the lower and upper leaves, respectively.
