What is the best nozzle type for herbicides?

• A. Flat-fan nozzle
• B. Cone nozzle
• C. Pencil jet
• D. Hollow cone

Answer: (A)

The key idea is how nozzle type affects spray pattern, droplet size, and drift, which in turn determines how well the herbicide covers turf or ornamentals. For broad-area herbicide applications, you want even coverage across the target surface. A flat-fan nozzle creates a uniform, flat spray that lays down a wide, continuous band and overlaps well with passes, giving consistent coverage across the treated area. It typically produces a medium droplet size at common pressures, balancing good deposition on leaves with manageable drift. The other nozzle types tend to have drawbacks for broadcast turf applications: a pencil jet concentrates spray into a narrow, high-velocity stream with higher drift risk and poor area coverage; a hollow-cone pattern can leave gaps in coverage on flat turf; a cone nozzle often generates smaller droplets with greater drift potential. So flat-fan is the best choice for herbicides in ornamental and turf settings.
