Which type of weeding technique relies on the application of physical forces?

The correct answer is mechanical control because this technique involves the use of physical methods to manage weeds. Mechanical control encompasses practices such as hoeing, tilling, mowing, or pulling weeds by hand, all of which utilize tools or manual labor to physically remove or disrupt weeds and their roots. This method is effective in reducing weed populations without the use of chemical herbicides, and it allows for immediate action against visible weeds.

Cultural control, on the other hand, focuses on using agricultural practices to create a healthy environment for desired plants while reducing the habitat for weeds. Preventive control involves strategies that prevent weeds from establishing in the first place, such as using mulch or selecting competitive crops. Pesticidal control includes the application of chemical herbicides to target and kill weeds. Unlike mechanical control, these other methods do not rely primarily on physical forces to manage weed populations.
