Using insects to control specific weeds is an example of which control method?

• A. Mechanical Control
• B. Chemical Control
• C. Manual Control
• D. Biological Control

Answer: (D)

Using a living organism to reduce weed populations is biological control. In this approach, natural enemies like insects are used to attack the weed, feeding on it, reproducing, and potentially establishing a self-sustaining population that helps keep the weed in check over time. This differs from mechanical control (physically removing or destroying weeds), chemical control (using herbicides), or manual control (hand-pulling). Biological control can be targeted and reduce reliance on chemicals, but it may take time to establish and must be managed to avoid impacts on non-target plants.
