The use of plant protection products are the most effective method to protect crops from pests. The primary goal of procedure is to spray as effective as possible to control pests. The effectiveness of this, like the level of pesticide use and safety during procedure depends largely on the quality of the liquid spray atomization. One of the three determinants of the quality of the procedure spray is the degree of coverage of sprayed objects. However, both the coverage and the other two – applying the liquid spray and the uniformity distribution of liquid. None of these indicators do not take into account the characteristics of the plant spray. Therefore, the UP Institute of Agricultural Engineering in Wroclaw was conducted a two-phase study, whose aim was to show the degree of coverage of sprayed objects in the aspect of the characteristics of sprayed plants in the flat field crops.

Pesticides used in agriculture during chemical plant protection against pests pose a significant threat to the environment. Pesticide should be characterized by: high toxicity in relation to pests and low toxicity compared to other organisms, adequate durability and high susceptibility to degradation. In practice, the achievement of these goals is often impossible. The aim of the study was, therefore, to use a parametric characterization of sprayed plant in the aspect of the process of spraying. In order to do this study the degree of coverage of sprayed objects using selected nozzles assessing which of the tested nozzles has the best properties in terms of covering horizontal and vertical surfaces sprayed plants. In the second part of the study was performed parametric characteristics selected for plant research at the surfaces of vertical and horizontal projections and ratio settings sprayed surface.
