Using a plow to destroy weeds is an example of which type of mechanical control method?

• A. Cultural control
• B. Cultivation
• C. Biological control
• D. Chemical control

Answer: (B)

Mechanical control methods rely on physical actions to kill or suppress pests. Using a plow to destroy weeds fits cultivation because tillage directly disturbs the ground to disrupt weed plants, uprooting them, severing roots, and burying weed seeds so they are less likely to germinate and compete with the crop. This direct manipulation of the weed population and its habitat is what defines cultivation. Cultural control would involve changing farming practices to prevent weeds (like crop rotation or timing), biological control uses living organisms to reduce pests, and chemical control uses herbicides. So the plow-based approach is cultivation, a mechanical method.
