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 quality of wheat spraying obtained while applying drift guard Turbo TeeJet 11 O 02 VP nozzles was tested. A standard boom and a boom equipped with an air sleeve were applied. Krukowiak-Bravo sprayer was used to test the influence of the air flux. The coverage was estimated on water sensitive papers. The spray coverage of wheat with TT 11 O 02 VP nozzles was satisfactory, both in case of conventional and air assisted applications.
