Which of the following is an example of cultural and mechanical control?

Mowing weeds is an excellent example of cultural and mechanical control because it utilizes physical methods to manage weed growth without relying on chemical applications. This practice is part of integrated pest management, where physical removal or suppression of unwanted plants is conducted to reduce competition for resources such as light, water, and nutrients. By regularly mowing, particularly before weeds can set seed, the population can be effectively controlled over time.

Cultural controls generally involve practices that enhance plant health and reduce pest susceptibility through management strategies such as crop rotation, varying planting times, and maintaining healthy soil conditions. Mechanical control focuses on physical methods, like mowing or tilling, to eliminate pests or weeds. Mowing fits both definitions, as it not only helps keep weeds in check but also promotes a healthier environment for desirable plants.

In contrast, other options like applying pesticides, using traps, or fumigation involve chemical or artificial means of control rather than mechanical or cultural methods. These approaches may play a role in pest management but do not align with the principles associated with cultural and mechanical controls.
