A prototype sprayer was constructed with its nozzle holder booms forming a kind of tunnel that travels over the plants. Spraying is thus performed in an enclosed space, preventing the shower of droplets from being blown away by the wind, reducing theevaporation rate and giving a very short distance between the nozzles and the plant surface. The efficiency of the applications was determined using water-sensitive paper and an in-house artificial vision system. The results show that the mean coverage percentage exceeded 54 % - sometimes reaching up to 79 %.
