ABSTRACT
An air-carrier (air blast) sprayers, frequently used like spray equipment for orchards was tested in traveling conditions, in order to establish spray deposition at different locations (heights) and also the relationship between air velocity distribution and spray deposition. Another important issue was determining the uniformity of distribution to the direction of the travel. For that purpose were used samples of tissue paper placed in a vertical plane, at three different distances from the center line of the sprayer. In order to quantify spray deposition on the traveling direction, placing samples of tissue paper was also made on this direction. Spray solution was applied at 1200 L/ha volume rate, at a displacement velocity of 3,2 km/h. Measurements of air velocity in traveling conditions were achieved using a wire anemometer, set at each location. Spray deposition decrease with increasing of work height, distance from the fan outlet, and also with the decreasing of air velocity.

Keywords: spray deposition, air velocity, volume rate, sprayer, axial fan
