Weed control is a type of pest control, which attempts to stop or reduce growth of weeds, especially noxious weeds, with the aim of reducing their competition with desired flora and fauna including domesticated plants and livestock, and in natural settings preventing non native species competing with native species.
Organic weed management promotes weed suppression, rather than weed elimination, by enhancing crop competition and phytotoxic effects on weeds. [57] Organic farmers integrate cultural, biological, mechanical, physical and chemical tactics to manage weeds without synthetic herbicides .
A primary element of organic lawn management is the use of compost [2] and compost tea to reduce the need for fertilization and to encourage healthy soil that enables turf to resist pests. [3] A second element is mowing tall (3" – 4") to suppress weeds and encourage deep grass roots, [ 4 ] and leaving grass clippings and leaves on the lawn as ...
Non-pesticidal Management (NPM) describes various pest-control techniques which do not rely on pesticides. It is used in organic production of foodstuff, as well as in other situations in which the introduction of toxins is undesirable. Instead of the use of synthetic toxins, pest control is achieved by biological means.
Several factors influence the effectiveness of soil-applied herbicides. Weeds absorb herbicides by both passive and active mechanisms. Herbicide adsorption to soil colloids or organic matter often reduces the amount available for weed absorption. Positioning of the herbicide in the correct layer of soil is very important, which can be achieved ...

Smother crops reduce dependence on chemical weed control, [3] and are sometimes used in the transition to organic farming. [4] Secondary benefits of such crops include helping nitrogen fixation in soil (if legumes are used) and reducing soil erosion.
