What are examples of mechanical weed management?

• A. Cultivation, hand pulling
• B. Herbicide application
• C. Biological control
• D. Solarization

Answer: (A)

Mechanical weed management relies on physical actions that remove or disrupt weeds without using chemicals or living organisms. Cultivation and hand pulling fit this idea because they physically uproot or cut weeds, directly reducing their presence in the bed or garden. By tilling soil or pulling weeds by hand, you remove the plant plus much of its root system, and you can do this precisely where you don’t want to disturb crops.

Other methods involve non-mechanical approaches: applying herbicides uses chemicals to kill or suppress weeds; biological control relies on organisms to reduce weed populations; and solarization uses heat from the sun under plastic to kill weeds in place, which is a physical method but aims at killing plants in the soil rather than physically removing them. In many teaching materials, those are categorized separately from mechanical removal because they don’t involve uprooting or physically disturbing the weeds with tools.
