Abstract
Matching spray volume to tree sizes and shapes can reduce chemical application, thus reducing operational costs and environmental pollution. A tree-specific variable volume precision orchard sprayer, guided by foliage shape and volume (canopy density sprayer; CDS) was developed. The spray and air volume is adjusted to tree variation of the foliage shapes and volumes of mapped trees. Tree mapping is done with stereoscopic aerial photography. Position of the sprayer in the orchard is linked to the mapped tree information from a GIS by RTK-DGPS. Spray deposition and biological efficacy and spray drift were evaluated in an orchard situation. Future developments on crop adapted spraying are highlighted.
