Mechanical destruction of weeds. A review [PDF]
Agronomy for Sustainable Development, 2007 The various methods of mechanical removal of weeds in relation to their biology are reviewed. Depending on the stage of growth and type of weed, i.e. the depth at which new shoots can be formed and the ability to withstand burial, implements inflict damage on weeds in different ways: cutting, burial or uprooting.

Advances in mechanical weed control technologies [PDF]
, 2022 Mechanical weed control can be grouped into three categories: full-width cultivators, inter-row cultivators and intra-row cultivators. This chapter will highlight the most recent and relevant advances within each category. The focus will be on novel inventions and developments of mechanical devices, designs, and the weed problems they are meant to ...
