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.
