To reduce spray drift for trellis-trained orchard crops, we manufactured an experimental orchard sprayer to use spray arms that could spray closer to trellis, with flat fan nozzles. In a vineyard, a drift distance was reduced from 30 m at spraying by the conventional orchard sprayer with a fan's air volume of 4.8 m cubic 3 /s to 10 m with either no air blast or an air volume of 3.2 cubic m /s at spraying by the orchard experimental sprayer. In a Japanese pear orchard, it is not clear that drift was reduced when the air volume was reduced from 4.8 cubic m /s with the conventional orchard sprayer to 3.2 cubic m /s with the experimental orchard sprayer.
