What do spray nozzles primarily control?

• A. Pesticide label compliance.
• B. Rate of material, droplet size, and spray distribution pattern.
• C. Tank capacity.
• D. Power consumption.

Answer: (B)

Spray nozzles control how much material comes out, the size of the droplets, and how the spray is spread across the target. The nozzle’s orifice size and design, along with the operating pressure, determine the flow rate (volume per time) and the droplet size category (fine to coarse). The nozzle shape sets the spray distribution pattern (cone or flat fan, swath width, and uniformity), which affects coverage and drift risk. So the best answer is the one that ties together rate, droplet size, and distribution pattern. The other choices relate to aspects outside the nozzle’s control, such as label compliance, tank capacity, or power consumption.
