MITIGATION OF THE EFFECTS OF PESTICIDE DRIFT APPLIED BY UNMANNED AERIAL VEHICLES

Resumo

The application of agricultural pesticides has proven to be crucial in controlling pests and diseases in various crops. Recently, the use of unmanned aerial vehicles (UAVs) or UAVs has gained prominence due to the precision and efficiency they provide. However, pesticide drift during aerial application remains a significant concern as it can cause contamination of non-target areas, affecting human health and the environment. This summary aims to discuss techniques and practices to mitigate the effects of pesticide drift applied by UAVs.

UAV technology allows for more localized and controlled application of agricultural pesticides, which in theory can reduce drift. Recent studies highlight advances such as specialized nozzles and real-time spray control systems designed to minimize smaller particles that are more susceptible to wind displacement (ZHAO et al., 2023). Additionally, efficient route programming and application during favorable weather conditions are strategies that show potential in reducing drift.

Climatic conditions such as wind, temperature, and relative humidity play a central role in pesticide drift. Application in cooler temperatures and low wind speeds can significantly reduce particle dispersion outside the target area (LI et al., 2024). The implementation of meteorological sensors in UAVs can provide real-time data to decide whether to suspend or continue spraying, promoting safer and more effective application.
