Which statement is true about protecting bees from pesticide injury?

• A. It is best to spray crops when they are in bloom
• B. Applying pesticides in the evening or during early morning is recommended
• C. Wettable powders are the safest formulation for preventing bee injury
• D. Aerial applications are less hazardous to bees than ground applications

Answer: (B)

Applying pesticides in the evening or during early morning is indeed the best practice to protect bees from pesticide injury. Bees are generally less active during these times, which reduces their exposure to pesticide applications. Many flowering plants, which are attractive to pollen foraging bees, tend to be less busy with bee activity in the cooler morning and evening temperatures. As such, pesticide application during these times aligns with the goal of minimizing the risk of bee exposure.

Spraying crops when they are in bloom could lead to higher levels of bee exposure since many pollinators are actively foraging during this time. While wettable powders can be less toxic in some cases, they do not inherently prevent bee injury as their formulation can still cause harm. Aerial applications tend to cover larger areas more quickly and may actually increase the risk of pesticide drift, potentially creating a greater hazard to nearby bee populations compared to ground applications. Therefore, the timing of pesticide applications is crucial for minimizing risk to bees, making the suggestion to apply in the evening or early morning the correct approach.
