What are the two main tasks involved in the calibration of a liquid spray system?

The calibration of a liquid spray system is fundamentally about ensuring the equipment operates efficiently and effectively to achieve the desired application rate and coverage. The first main task, determining nozzle size, is crucial because it affects droplet size, spray pattern, and overall distribution of the pesticide. Selecting the correct nozzle size ensures that the right volume of pesticide is released and that it effectively targets the intended pests or plants.

The second key task, checking the application rate, involves measuring how much liquid is being applied to a specific area over a certain period. This ensures that the correct amount of pesticide is being used, which is vital for both efficacy and safety—over-application can lead to environmental harm, while under-application may not control pests effectively.

Together, these two tasks ensure that the spraying system is both effective and compliant with regulations to minimize risk and enhance the effectiveness of pest control strategies. Thus, the focus on these tasks is integral to the successful use of aerial application in agricultural practices.
