The purpose of applying an additional air flux in field sprayers is limiting liquid drift. The flux also influences the quality of plant spraying. Air Plus Spridotrain sprayer, produced by RAU company, was applied in the research on the influence of air flux on the quality of coverage ofwinter wheat (Roma variety). The plant coverage was determined using water sensitive papers.

The purpose of applying an additional air flux in field sprayers is limiting liquid drift. The flux also influences the quality of plant spraying. Krukowiak Bravo sprayer, produced by Krukowiak Company, was applied in the research on the influence of air flux on the quality of coverage ofwinter wheat (Sakwa variety). The plant coverage was determined using water sensitive papers. The objective of the experiment was to evaluate the influence of air volume discharged by the air sleeve equipped sprayer and air induction nozzles on the coverage of the plant. The spray coverage ofwheat with ID 120-03 Lechler nozzles was satisfactory, both in case of conventional and air assisted applications.
