The effects of several spray-boom shield designs and “low-drift” nozzles on spray deposition are presented. Results are based on experiments conducted in a wind tunnel and computer simulations using the same experimental parameters. Performances of all experimental shields were evaluated under two spray pressures (0.15 and 0.3 MPa), and two air flow rates (2.75 and 4.80 m/s) in the wind tunnel. All nine shields tested during this study effectively reduced droplet deposition distance. Even the least effective shield design produced a 13% improvement in deposition of spray on the ground. A double-foil shield produced the best spray-deposit improvement of 59% compared to the same nozzles spraying without the shield. The shields were effective even when used with nozzles with higher flow rates (producing fewer small droplets). However, using larger capacity nozzles reduced droplet deposition distance more than using smaller capacity nozzles with even the most effective shield. Low-drift (LD) nozzles without a shield provided reductions in deposition distance ranging from 20 percent to 67 percent when compared to the deposition distance from a 0.61 L/min standard flat-fan (SFF) nozzle operating under identical conditions. The 0.61 L/min SFF nozzles operating with Shield 2 (the best shield) was twice as effective in reducing droplet deposition distance as the same capacity LD nozzles operating without a shield. However, the low-capacity LD nozzles without a shield were twice as effective in reducing drift as the SFF nozzles of the same capacity operating with Shield 5/1 (the shield with the worst performance). Without a shield, LD nozzles at higher flow rates are no more advantageous in reducing droplet deposition distance than SFF nozzles of similar flow rate.
