Which of the following is an example of mechanical control?

• A. Bt bacteria
• B. Atrazine
• C. Cyfluthrin
• D. Burning and burying

Answer: (D)

Mechanical control uses physical, non-chemical means to reduce pest populations. Burning and burying fits this approach because it directly destroys pests or their habitat through heat or disposal, removing them without using pesticides or living organisms. Bt bacteria is a biological control method, using a living organism or its toxin to target pests. Atrazine and Cyfluthrin are chemical controls, relying on chemical substances to kill pests.
