Which of the following describes mechanical control methods in pest management?

Mechanical control methods in pest management refer to the physical removal or manual methods employed to manage pest populations. This approach includes techniques such as trapping, handpicking, mowing, tilling, and using barriers like nets or row covers. These methods can effectively reduce pest numbers without the use of chemicals, making them an environmentally friendly option.

Unlike the other choices, which describe chemical applications, biological factors, or conditions that affect plant growth, mechanical control is focused specifically on direct action against pests. By utilizing tools and physical processes, mechanical methods can disrupt pest life cycles and minimize their damage while also providing immediate results. This makes them an important part of Integrated Pest Management (IPM) strategies.
