Seven hydraulic nozzle types (standard-ST;
hollow cone-KH; multirange-LU; standard with narrow angle-STD; antidrift-AD;
air-induction-IDK; twinjet air-induction-IDKT) were compared in terms of spray
transfer and drop penetration. Spray treatments were carried out at a constant
application volume of 90 L ha-1 with a linear-motion simulator. WSP’s
were placed onto metal poles and into artificial plant at both horizontal and
vertical planes. Two different operating pressures (250 and 500 kPa) and the
nozzle position angles (0º and 45º) were used in the experiments. Spray
transfer levels at vertical plane were quite lower than the spray transfer levels
at horizontal plane. The greatest spray coverage was achieved with LU and ST
nozzles producing fine droplets. The greatest drop penetration at vertical
plane was obtained from IDK nozzle. Only 25% of the drops transferred to the
open target reached the stem and root collar region of the plant canopy. With
increasing operating pressures, spray coverage increased by 1,17 times at
horizontal plane and 1,50 times at vertical plane. With increasing nozzle
position angles, spray coverage at vertical plane increased by 40%. The
greatest coverage was achieved on front surface of the vertical target and
drops reaching to side and rear surfaces were quite low.
