When should precautions against pesticide drift be heightened?

• A. On calm, clear days.
• B. When applying near bodies of water.
• C. When using large droplet nozzles.
• D. During early morning or late evening applications.

Answer: (B)

Heightened precautions against pesticide drift are particularly important when applying near bodies of water due to the potential risk of contamination of aquatic ecosystems. Pesticides can have harmful effects on aquatic organisms, and even small amounts that drift into water sources can lead to significant environmental damage. Additionally, these areas often have stricter regulations to protect water quality and wildlife. Therefore, it is essential to exercise extra caution during applications in these regions to prevent unintended pesticide movement into the water. In contrast, although calm and clear days may seem ideal for application due to reduced wind, they do not directly correlate with the need for heightened precautions as much as proximity to water does. Large droplet nozzles are typically designed to reduce drift, thereby potentially lowering the risk of drift rather than increasing it. Early morning or late evening applications can also be advantageous and are often recommended to minimize drift due to lower temperatures and winds, which further emphasizes the significance of proper timing and technique rather than highlighting a need for increased caution.
