Which of the following are types of mechanical control?

• A. Exclusion, trapping, cultivation
• B. Trapping, pesticide application, cultural practices
• C. Exclusion, trapping, cultivation, mulching
• D. Pesticide application, chemical control, trapping

Answer: (C)

Mechanical control refers to methods that physically manage pest populations without the use of pesticides. The correct response includes exclusion, trapping, cultivation, and mulching, which are all effective strategies for pest management.

Exclusion involves barriers to prevent pests from entering an area, while trapping captures pests to reduce their population. Cultivation practices can modify the environment, making it less hospitable for pests. Mulching can suppress weed growth and manage soil moisture, indirectly reducing pest establishment and survival.

By utilizing these mechanical methods, individuals can effectively manage pest populations through physical means, minimizing the need for chemical interventions and promoting sustainable practices.
