Evaluation of Tunnel Sprayer Systems for Dwarf Fruit TreesPublished by the American Society of Agricultural and Biological Engineers, St. Joseph, Michigan www.asabe.org Citation: Applied Engineering in Agriculture. 11(6): 817-821. (doi: 10.13031/2013.25807) @1995Authors: D. L. Peterson, H. W. Hogmire Keywords: Sprayer systems, Fruit trees, Tunnel, Drift. Two types of spray systems were tested in a tunnel sprayer with different configurations and operating parameters. Two pairs of opposing cross-flow fans yielded the most uniform deposition on the target trees and least deposition on the downwind tree row; but results of two sets of three opposing Proptec fans were improved over previous tests. Deposition to the downwind row did not appear to be a serious problem; but 14 to 37% of the spray material was deposited onto the ground within the tunnel sprayer. Spray deposition at 8 km/h (5 mile/h) was as effective as it was at 4.8 km/h (3 mile/h)."/> Two types of spray systems were tested in a tunnel sprayer with different configurations and operating parameters.
