Which of the following best describes mechanical control?

• A. Using chemical pesticides excessively
• B. Utilizing machines to disrupt pest habitats
• C. Applying biological agents to eliminate pests
• D. Unconventional methods like growth hormones

Answer: (B)

Mechanical control encompasses techniques that physically disrupt pest habitats or remove pests without the use of chemical or biological control methods. This can involve practices such as trapping, tilling the soil to disrupt pest life cycles, or using barriers to prevent pests from reaching crops. By utilizing machines or mechanical devices, this method aims to reduce pest populations effectively without introducing chemicals into the environment, making it a more eco-friendly option.

The other choices represent different pest management strategies that do not fit the definition of mechanical control. Using chemical pesticides excessively refers to chemical control, while applying biological agents pertains to biological control methods. Unconventional methods like growth hormones fall under alternative approaches that may not directly involve mechanical intervention. The correct description focuses on the physical and mechanical methods used to manage pest issues.
