The aim of the paper was to characterize trailed field sprayers that are available on the market and parameters standardizing their actions, as well as technological advances. A comparison was made between the most important features, that condition functioning of exemplary equipment from various known brands. The research results indicate current possibilities of performing the procedure of field spraying with the use of available models of sprayers. Therefore, it could be concluded that parameters and characteristics of all researched trailed field sprayers models do not assure satisfying effectiveness of spraying process, which stands at a very low level in a large number of cases. Performed analysis show the necessity of conducting intensive work to perfect field spray effectiveness, which is a condition of dynamic agricultural development.
