The AirJet bi-fluid nozzle mixes air with the spray solution inside the nozzle to atomize the spray. The AirJet can produce droplets of consistent size at a wide range of flow rates. Unlike conventional nozzles, the AirJet will not change droplet size as rates and pressures change. The quality of wheat spraying obtained while applaying AirJet TK-VS10 nozzles was tested. The coverage was estimated on water sensitive papers. Nozzles were used at the liquid pressure: 0.22; 0.28; 0.35 MPa and air pressure: 0.07; 0.08; 0.09; 0.1 MPa. Relatively low spray volumes 90 l/ha, 110 l/ha and 150 l/ha were obtained at constant working speed of 6 km/h
