Must be used with special caution near bee hives since bees may carry them back to the hive and poison the entire colony?

• A. Microencapsulated herbicide
• B. Emulsifiable concentrate
• C. Wettable powder
• D. Granular pesticide

Answer: (A)

Bees can carry materials they encounter during foraging back to the hive, which can poison the colony if the active ingredient is toxic to bees. Microencapsulated products release the active ingredient in tiny capsules that can cling to bees or be taken back to the hive via pollen or nectar stores. These capsules can persist and slowly release toxin inside the hive, affecting brood and the whole colony. Because of this behavior, microencapsulated formulations require especially careful use near bee hives. Other forms—like emulsifiable concentrates, wettable powders, or granular pesticides—pose risks too, but the encapsulated form is notably prone to being transported by bees and delivering ongoing exposure inside the hive.
