Although there are alternative methods of struggle against diseases, pests and weeds in agricultural production, chemical control method is widely preferred. The ability of the pesticide to show sufficient effect on the target surfaces depends on the correct functioning of the nozzles. In plant protection applications, it is necessary to make the pesticide in the appropriate nozzle type, spraying height, spraying pressure, forward speed and norm values. This study was carried out to determine the surface coverage, droplet frequency and volume median diameter of different air induction nozzles at different spraying heights and spray pressures. In the study; four different nozzles, three with air induction (ID 90-03 C, IDK 120-03, AITX B 8003) and one with hollow cone nozzle (TR 80-03), were used. This study conducted in field conditions. Two different spray heights (50 cm, 70 cm) and three different spray pressures (2 bar, 4 bar, 6 bar) were applied. As a result of the applications, the volume median diameter, droplet frequency and surface coverage were examined. Water sensitive papers and Image Tool for Windows V3 image processing program were used to determine the volume median diameter and surface coverage. The excel program was used to calculate the droplet frequency values. According to the results of the research, the highest surface coverage rate was achieved with 37.29% at IDK 120-03 nozzle at 70 cm spraying height and 6 bar spray pressure. The lowest surface coverage was obtained with the TR 80-03 nozzle at a spray height of 70 cm and pressure of 6 bar with 9.33%. The largest volume median diameter was 547.01 µm in AITX B 8003 nozzle and 256.60 µm in the smallest volume median diameter TR 80-03 nozzle. The highest droplet frequency is 74 (pcs / cm2) at TR 80-03 nozzle with 50 cm spraying height and 2 bar spray pressure, while the lowest droplet frequency is 8 (pcs / cm2) at 50 cm spray height and 2 bar spray pressure at AITX B 8003 nozzle was obtained.
