Abstract
Apple trees were sprayed with air sprayers with two different cross flow fan arrangements, giving: 1) converging air jets 2) horizontal, parallel air jets. Deposition, measured on artificial targets with fluorescent dye, showed 50 % higher application values and a more uniform distribution pattern in the canopy when converging air jets were used. Maximum air velocities were measured in the same positions in the canopy and correlated with the deposition results. Losses, measured behind the trees, appeared lower down (beneath the tree top level) when converging fans were used.
