Which control option relies on living organisms to suppress weed populations?

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

Answer: (C)

Biological control uses living organisms to reduce weed populations. This means introducing or encouraging natural enemies—such as insects, mites, fungi, or other pathogens—that specifically target the weed, slowing its growth, reproduction, or spread. The approach aims for long-term suppression with minimal chemical use and tends to be quite targeted, helping protect other plants in the area. This differs from mechanical control, which relies on physical removal or disruption; chemical control, which uses herbicides; and cultural control, which changes management practices to make the environment less favorable for weeds. Biological control shines in being ecosystem-oriented and reducing reliance on chemical inputs, though establishment can take time and success varies with conditions.
