Why are flat-fan nozzles preferred for herbicides?

• A. Provide uniform distribution on a boom
• B. They minimize drift
• C. They are the cheapest option
• D. They require no calibration

Answer: (A)

Uniform distribution across the spray width is essential for effective herbicide control on turf and ornamentals. Flat-fan nozzles produce a broad, flat spray pattern that delivers a consistent flow across the entire width of the nozzle’s swath. This means the target area receives even coverage as the boom moves, reducing gaps or overdosed spots and improving overall efficacy with fewer reapplications. Drift and cost are considerations in nozzle selection, but they aren’t the main reason flat-fan nozzles are preferred for herbicides; even flat-fan setups require careful calibration to ensure the correct rate and uniform pattern.
