Which statement best describes mechanical control?

• A. Using chemical pesticides
• B. Using crop rotation only
• C. Using biological controls
• D. Using mechanical devices or manual methods to manage pests

Answer: (D)

Mechanical control means using physical means to reduce pest problems, not chemicals or living organisms. It relies on actions or devices you can touch or operate: hand-picking pests off plants, traps, barriers like row covers or screens, or physical destruction. Tillage or sanitation to remove breeding sites are also mechanical methods. The core idea is the method relies on physical interaction with the pest or its environment rather than sprays or biological agents. So the statement that best describes mechanical control is using mechanical devices or manual methods to manage pests. In contrast, chemical pesticides use chemicals, biological controls rely on natural enemies, and crop rotation is a cultural practice that changes the environment or timing rather than applying a mechanical solution.
