Why should pesticide equipment calibration be rechecked frequently?

To confirm the pesticide mixture is effective
To account for wear and changes in delivery rate
To ensure compliance with regulations
To reduce the number of applications needed

The correct answer is: To account for wear and changes in delivery rate

Pesticide equipment calibration should be rechecked frequently primarily to account for wear and changes in delivery rate. Over time, equipment such as sprayers can experience wear, leading to variations in output and possibly altering the amount of pesticide being applied. Even slight changes in pressure, nozzle wear, or hose condition can significantly affect the delivery rate and distribution of the pesticide. Regular calibration ensures that the equipment is functioning correctly and applying the intended amount of pesticide, which is crucial for both effectiveness and safety. By maintaining accurate calibration, applicators can achieve desirable control over pests while minimizing risks to the environment, crops, and non-target species. This practice also aids in achieving the most economical and effective use of pesticides, which aids in sustainable management practices.
