What is the primary purpose of sprayer calibration?

The primary purpose of sprayer calibration is to ensure the correct amount of pesticide is applied. Calibration allows applicators to adjust the equipment settings to match the necessary application rate for the specific pesticide being used. This is crucial because applying too much pesticide can lead to harmful environmental effects, pest resistance, and damage to the crops or surrounding landscape. Conversely, applying too little may not effectively control the target pests, resulting in crop loss or diminished yield.

By calibrating the sprayer, applicators can ensure that they are using the appropriate pressure, speed, and nozzle size to achieve a uniform distribution of the pesticide at the intended rate. This not only promotes safety and efficacy but also supports responsible pesticide use, minimizing potential negative impacts on health and the environment.
