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.
Tribulus terrestris is an annual plant in the caltrop family (Zygophyllaceae) widely distributed around the world. It is adapted to thrive in dry climate locations in which few other plants can survive.
Cenchrus setaceus, commonly known as crimson fountaingrass, is a C4 perennial bunch grass that is native to open, scrubby habitats in East Africa, tropical Africa, the Middle East and south-western Asia. It has been introduced to many parts of the world as an ornamental plant, and has become an invasive species in some of them. It is drought-tolerant, grows fast, reaches 3 feet in height, and has many purple, plumose flower spikes.
Pennisetum is a widespread genus of plants in the grass family, native to tropical and warm temperate regions of the world. They are known commonly as fountaingrasses. Pennisetum is considered a synonym of Cenchrus in Kew's Plants of the World Online.
Holcus lanatus is a perennial flowering plant in the grass family Poaceae. The specific epithet lanatus is Latin for 'woolly' which describes the plant's hairy texture.

Sonchus arvensis, the field milk thistle, field sowthistle, perennial sow-thistle, corn sow thistle, dindle, gutweed, swine thistle, or tree sow thistle, is a species of flowering plant in the family Asteraceae. S. arvensis often occurs in annual crop fields and may cause substantial yield losses.
The tropical grass species Cenchrus clandestinus is known by several common names, most often Kikuyu grass, as it is native to the highland regions of East Africa that is home to the Kikuyu people. Because of its rapid growth and aggressive nature, it is categorised as a noxious weed in some regions. However, it is also a popular garden lawn species in Australia, New Zealand, South Africa and the southern region of California in the United States, as it is inexpensive and moderately drought-tolerant. In addition, it is useful as pasture for livestock grazing and serves as a food source for many avian species, including the long-tailed widowbird. The flowering culms are very short and "hidden" amongst the leaves, giving this species its specific epithet (clandestinus).
Alternanthera caracasana is a species of flowering plant in the family Amaranthaceae known by the common names khakiweed, washerwoman and mat chaff flower. It is native to Central and South America but is well-known elsewhere as a noxious weed. It is naturalized in some areas and invasive in others and can be found across the southern half of the United States, Australia, Spain and parts of Africa. The plant has long, prostrate stems covered in small leaves which vary in shape from diamond to rounded. It grows from a rhizome and often roots from its lower nodes. Each spike inflorescence is under a centimeter wide and is covered in tiny stiff white flowers. This is a tough weed of lots, roads, railroad tracks, cleared areas, and other places that are rough, sandy, and often well-traveled.
Cenchrus echinatus is a species of grass known by the common names southern sandbur, spiny sandbur, southern sandspur, and in Australia, Mossman River grass. It is native to North and South America. It is a clump-forming annual grass growing up to 80 cm (31 in) tall. The leaves occur with or without hairs and measure up to 12 mm (0.47 in) wide. The ligule is a fringe of hairs. The grass has barbed burrs of 4–10 mm (0.16–0.39 in) long.
Ambrosia confertiflora is a North American species of ragweed known by the common name weakleaf bur ragweed.
Ageratina adenophora, commonly known as Crofton weed, is a species of flowering plant in the family Asteraceae native to Mexico and Central America. Originally grown as an ornamental plant, it has become invasive into farmland and bushland worldwide. It is toxic to horses, which develop a respiratory disease known as Numinbah horse sickness after eating it.
Ambrosia tomentosa, the skeletonleaf bur ragweed, silverleaf povertyweed, or skeleton-leaf bursage, is a North American species of perennial plants in the family Asteraceae.
Cenchrus spinifex, known commonly as the common sandbur, coastal sandbur, or stickerweed, is a perennial grass that grows from 5 to 30 inches high in sandy or gravelly terrain. It is native to the southern United States southward into Mexico and the Caribbean. It has been introduced elsewhere in the United States and in the Philippines and South Africa. It is a noxious weed in Europe.
Themeda quadrivalvis is a species of grass known by the common names grader grass, habana grass, and kangaroo grass, not to be confused with Themeda triandra, which is also known as kangaroo grass. It is native to India, Nepal, and Malaysia. It can also be found in many other places as an introduced species and often a noxious weed. It occurs in the United States, New Caledonia, Fiji, Mauritius, Thailand, Indonesia, Papua New Guinea, China, the Middle East and tropical America. It is a troublesome exotic weed in Australia, especially in northern regions. It is also an agricultural weed in crops such as sugar cane and lucerne.
Bocconia frutescens is a species of flowering plant in the poppy family known by many common names, including plume poppy, tree poppy, tree celandine, parrotweed, sea oxeye daisy, and John Crow bush in English, gordolobo, llorasangre, tabaquillo, palo amarillo, palo de toro and pan cimarrón in Spanish, bois codine in French and bwa kodenn in Haitian Kreyòl. It is native to the Americas, including Mexico, parts of Central and South America, and the West Indies. It is perhaps better known in Hawaii, where it is an introduced species and an aggressive invasive weed with rapid negative effects on local ecosystems. In other parts of the United States it is used as an ornamental plant for its "tropical"-looking foliage.
Brachiaria mutica is a species of grass known by the common names para grass, buffalo grass, Mauritius signal grass, pasto pare, malojilla, gramalote, parana, Carib grass, and Scotch grass. Despite its common name California grass, it does not occur in California; it is native to northern and central Africa and parts of the Middle East, where it is cultivated for fodder. It was introduced elsewhere and it is now cultivated throughout tropical regions of the world for this purpose.
