Effect of angle of sprayer deflector on spray distribution in dwarf apple trees
Özet
The objective of the study was to determine the influence of the air jet direction by the deflector on the sprayer in canopy spray deposit and off-target loss in dwarf apple trees (Granny smith and Galaxy Gala). They were compared with three deflector angle (0-20-40°). The treatments were carried out in dwarf orchard. The sprayer with the air spouts set 20° upwards produced in orchards higher in canopy deposits and lower off-target loss than did 40°. Further rising of the air spouts and by that directing the air jets 40° upwards increased the spray loss and risk of air bone drift with worse deposits of spray. © 2008 Asian Network for Scientific Information.
