Which of the following best describes the consequence of applying pesticides without proper calibration?

Applying pesticides without proper calibration can lead to the risk of over-application. Calibration ensures that the correct amount of pesticide is applied to effectively control pests while minimizing potential environmental harm and reducing the risk of residue violations. When calibration is not performed adequately, the applicator may apply too much product, which can result in several negative consequences, such as harming non-target organisms, contaminating water supplies, or causing phytotoxicity (plant damage). This over-application can also lead to increased costs due to excessive pesticide use and potential legal issues if residues exceed regulatory limits. Understanding the importance of calibration in pesticide application helps ensure safety, efficacy, and compliance with regulations, ultimately supporting sustainable agricultural practices.
