What is the primary purpose of sprayer calibration?

The primary purpose of sprayer calibration is to ensure uniform distribution of pesticide across the targeted area. When sprayers are properly calibrated, they help to achieve consistent application rates, which is essential for effective pest control. Uneven distribution can lead to inadequate pest management, as some areas may receive too little pesticide, while others may receive too much, leading to possible crop damage or pesticide resistance.

Uniform application also plays a critical role in environmental protection. Over-application can result in runoff and contamination of water sources, while under-application can lead to increased pest populations and further chemical use. Therefore, while minimizing environmental impact, reducing costs, and complying with regulations are important aspects of pesticide use, they are secondary to the fundamental need for uniform pesticide application during sprayer calibration.
