To protect bees from pesticide injury, when is applying pesticides recommended?

• A. In the evening or during early morning
• B. At noon
• C. At midnight
• D. In the late afternoon

Answer: (A)

Protecting bees means choosing a time when they are least likely to be foraging and coming into contact with the pesticide. Applying in the evening after foraging has ended or in the early morning before bees start foraging minimizes exposure, because bees aren’t actively visiting flowers and are back at the hive. Cooler temperatures at these times also reduce spray drift and pesticide volatilization, making it less likely that residues reach blossoms or bee colonies. In contrast, spraying at noon or in the late afternoon coincides with ongoing foraging, increasing the chance bees encounter the pesticide. Midnight, while potentially reducing exposure, is not practical for most applications, so the recommended window remains evening or early morning.
