Drift can be reduced by which formulation?

• A. Using high pressure
• B. Using the smallest nozzle
• C. Nozzles with large fan angles
• D. Using low pressure, the smallest nozzle possible, and nozzles with large fan angles

Answer: (D)

Drift is minimized when you produce larger droplets and reduce the spray’s momentum so fewer droplets stay airborne long enough to move off target. Using low pressure slows the spray and tends to form larger droplets, which are less prone to being carried away by wind. Pairing that with the smallest nozzle limits the flow and helps maintain coarser droplets rather than a fine mist, further reducing drift potential. Nozzles with large fan angles spread the spray over a wider area and, when designed to create coarser droplets (as with certain air-induction designs), promote deposition on the target instead of in the air or beyond it. Together, this formulation lowers drift while still aiming for effective coverage, though you must watch for adequate target coverage and adjust as needed.
