Weeding in the context of "Noxious weed"

A rake (Old English raca, cognate with Dutch hark, German Rechen, from the root meaning "to scrape together", "heap up") is a broom for outside use; a versatile horticultural implement consisting of a toothed bar fixed transversely to a handle, or tines fixed to a handle, and used to collect leaves, hay, grass, and in gardening, for loosening the soil, light weeding and to make furrows, mounds and levelling, removing dead grass from lawns, and generally for purposes performed in agriculture by the harrow. Depending on purpose, their materials and form will vary greatly.

Large mechanized versions of rakes are used in farming, called hay rakes, are built in many different forms (e.g. star-wheel rakes, rotary rakes). Non mechanized farming may be done with various forms of a hand rake. Rakes can be a mechanical component of a Threshing machine.

Mechanical pest control is the management and control of pests using physical means such as fences, barriers or electronic wires. It includes also weeding and change of temperature to control pests. Many farmers at the moment are trying to find sustainable ways to remove pests without harming the ecosystem.
