What precaution should be taken when aerially applying pesticides over congested areas?

When conducting aerial pesticide applications over congested areas, ensuring a recent inspection of the aircraft is crucial for safety and efficacy. This is because congested areas often have higher risks associated with non-target exposure, including human populations, pets, and sensitive environments. A thorough inspection helps to confirm that the aircraft is mechanically sound and that all systems, such as the spray system and navigational equipment, are functioning correctly.

A well-maintained aircraft is less likely to malfunction during flight, which is vital in managing the precision required for spraying in populated regions. Proper functioning minimizes risks, ensuring that the application adheres closely to planned flight paths and avoids drift that could affect unintended areas. This attention to safety helps protect public health and the environment, making it a fundamental aspect of responsible aerial pesticide application in areas with dense human activity.

In contrast, while options like using a drone, limiting the pesticide type, or applying at night may present valid strategies under specific conditions, they do not directly address the overarching need for equipment reliability and operational safety that is assured through a thorough inspection.
