Which applicator is associated with a hollow cone spray pattern?

• A. Flat fan nozzle
• B. Solid jet nozzle
• C. Mist nozzle
• D. Controlled Droplet Applicator

Answer: (D)

A hollow cone spray pattern is achieved by a nozzle/design that distributes droplets around the outer edge of the spray, creating a ring-like pattern with a central opening. This pattern is chosen in turf applications to improve coverage on the canopy while helping to control drift, because it can deliver a defined, controlled droplet distribution rather than a broad, solid spray.

The Controlled Droplet Applicator is specifically designed to produce this hollow-cone, controlled-droplet spray. It aims to balance effective coverage with drift reduction, which is why it’s the match for a hollow cone pattern.

In contrast, a flat fan nozzle makes a single, flat spray sheet, not a hollow cone; a solid jet nozzle emits a concentrated stream rather than a dispersed ring; a mist nozzle creates very fine droplets that are more prone to drift and do not form a hollow cone.
