Weed control refers to the botanical element of pest control, which aims at stopping weeds from offering competition to domesticated plants and livestock. Weeds that are usually aimed are those that are injurious or noxious. Several different methods of controlling weeds have been invented and they work with varying levels of efficiency. Weed control in Compass Point is offered by several service companies at affordable rates.

Weeds possess certain characteristics that make them not worth having among plants. To start with, weed plants may only have minimum value if they have any value at all. Plants are made valuable by being nutritional, material, medicinal, or energy sources. Weeds are also characterized by fast growth and easy germination. Finally, they offer competition to crops for water, light, space, and nutrients. The context under discussion is often based upon when defining the term weed.

Weeds vary a lot in their ability to compete with crops. The level of competition they offer depends on the season and prevailing conditions. Weeds do not necessarily cause harm to crops, especially during the early stages. However, as both crops and weeds grow, they start to require more space, nutrients, and water, causing competition. It is approximated that weeds can remain non-competitive with crops for a period of three weeks before they start causing harm.

Weeds are propagated through various methods, but seeding is the major method. Weed species that rely on seeding for propagation include hairy bittercress, groundsel, chickweed, speedwell, annual meadow grass, fat hen, and cleaver. Seed production may occur multiple times in very large numbers within a single season. Seed germination may occur at once or at different times. Seed dormancy may take up to years.

Weeds can be controlled through several different methods, which include coverings, manual removal, tillage, buried drip irrigation, thermal, seed targeting, stale seed bed, and crop rotation. In addition to these, other methods include animal grazing and application of herbicides. Methods differ in how effective they are. One may use multiple methods if the area is large, but often one method suffices.

The technique called covering uses weed mats to kill weeds. The weed mats are covered on an area where weeds are. These mats create a hostile environment so that the weeds cannot survive. Survival is made impossible because air and light supply are cut off by the covers. It takes up to a few weeks for the weeds to die off completely. Covers can be relocated elsewhere so that the process is repeated.

The use of manual removal of weeds is also applied in certain places. The weeds are manually plucked out of the soil and disposed. One must make sure to pluck the weed from the roots to prevent it from growing again. This method can be very hectic and slow if the area is very large.

In rice paddies, weeds are controlled through irrigation. Water is applied through irrigation to soak rice plants completely. Since rice is resistant to water, it survives very well. However, weed plants that cannot survive under water are often chocked and killed.
