What is true about accurate calibration of a sprayer?

Accurate calibration of a sprayer is crucial for effective and safe application of pesticides or other chemicals. The statement that it is the only way to know how much chemical is being applied underscores its significance in ensuring that the right amount is dispensed according to the specific requirements of the crop and the chemical label guidelines. When calibration is done properly, it allows the applicator to measure the output of the sprayer accurately, preventing under-application or over-application, both of which can have negative effects on plant health, pest control efficacy, and environmental safety.

This process involves measuring the flow rate of the sprayer and adjusting it to achieve the desired application rate. It is an essential step that needs to be performed regularly, not just occasionally, to ensure accuracy over time. Accurate calibration helps maintain compliance with regulatory standards and ensures that the application is effective, reducing waste and potential harm to non-target areas.
