In order to meet the pest control requirement of hedge crop, tunnel sprayer was researched to entrap the droplets which were not deposited on the target and recycled. Tunnel sprayer was compared with conventional air-assist orchard sprayer on anti-drift performance. The result showed that, the drift in air of tunnel sprayer was reduced by 97.9% compared with conventional orchard sprayer in down wind direction; the ground drift of tunnel sprayer was reduced by 99.3% in drift distance.
