Defoliating weeds instead of picking them by the roots is a great way to end up with a field of weeds.

Depends on the weed and the ground cover the weeds are competing against. For many weeds, simply mowing them in the presence of decent ground cover is completely effective, as they’re optimized to grow tall quickly - defoliate them at the right time and they’ve already spent their energy reserves.
