What is the primary purpose of calibrating a sprayer?

The primary purpose of calibrating a sprayer is to ensure uniform application. Calibration involves adjusting the equipment so that it delivers the correct amount of pesticide at the right pressure and spray pattern. This is crucial because uneven application can lead to areas that are either over-treated or under-treated, which may result in ineffective pest control and potential harm to non-target organisms or the environment. Proper calibration helps maintain the effectiveness of the treatment, ensuring that pest control measures are both safe and efficient.

While reducing operational costs, increasing sprayer longevity, and complying with regulations are important considerations, they are secondary benefits that can result from proper calibration rather than the main reason for it. Uniform application is the key objective, as it directly affects the success of pest management practices.
