What is necessary to ensure the correct amount of pesticide is delivered by a sprayer?

Recording
Calibration
Maintenance
Cleaning

The correct answer is: Calibration

Calibration is essential for sprayers to ensure that the correct amount of pesticide is delivered effectively and uniformly. When a sprayer is properly calibrated, it allows for precise control over the application rate, ensuring that the pesticide is applied in accordance with the label recommendations. This is important not only for the efficacy of the treatment but also for safety, as applying too much pesticide can damage plants and the environment, while applying too little may not adequately address the pest problem. Calibration takes into account factors such as nozzle size, pressure, and speed of application, providing a tailored approach to pesticide delivery.
