Echinochloa is a very widespread genus of plants in the grass family and tribe Paniceae. [3] [4] [5] Some of the species are known by the common names barnyard grass or cockspur grass. [6] [7]

Contents

Some of the species within this genus are millets that are grown as cereal or fodder crops. The most notable of these are Japanese millet (E. esculenta) in East Asia, Indian barnyard millet (E. frumentacea) in South Asia, and burgu millet (E. stagnina) in West Africa. Collectively, the members of this genus are called barnyard grasses (though this may also refer to E. crus-galli specifically), and are also known as barnyard millets or billion-dollar grasses.

When not grown on purpose, these grasses may become a nuisance to farmers. In particular, common barnyard grass (E. crus-galli) is notorious as a weed. [8] It is not easily suppressed with living mulches such as velvet bean (Mucuna pruriens var. utilis). [9] Early barnyard grass (E. oryzoides) is a well-known example of Vavilovian mimicry: the plants have evolved to resemble rice (Oryza), enabling them to escape weeding more easily. [10]

Among the plant pathogens that affect this genus are the sac fungus Cochliobolus sativus , which has been noted on common barnyard grass, and rice hoja blanca virus. Both affect many other grass species, in particular most important cereals, and Echinochloa weeds may serve as a reservoir. The fungi Drechslera monoceras and Exserohilum monoceras have been evaluated with some success as potential biocontrol agents of common barnyard grass in rice fields. More research is necessary, however, because they may not be host-specific enough to be of practical use. [11] Insect pests include Atherigona falcata , the barnyard millet shoot fly. [12]

<span class="mw-page-title-main">Millet</span> Group of grasses (food grain)

Millets are a highly varied group of small-seeded grasses, widely grown around the world as cereal crops or grains for fodder and human food. Most species generally referred to as millets belong to the tribe Paniceae, but some millets also belong to various other taxa.

<i>Panicum</i> Genus of grasses

Panicum (panicgrass) is a large genus of about 450 species of Poaceae grasses native throughout the tropical regions of the world, with a few species extending into the northern temperate zone. They are often large, annual or perennial grasses, growing to 1–3 m (3–10 ft) tall.

<span class="mw-page-title-main">Foxtail millet</span> Species of grass

Foxtail millet, scientific name Setaria italica, is an annual grass grown for human food. It is the second-most widely planted species of millet, and the most grown millet species in Asia. The oldest evidence of foxtail millet cultivation was found along the ancient course of the Yellow River in Cishan, China, carbon dated to be from around 8,000 years before present. Foxtail millet has also been grown in India since antiquity.

<i>Echinochloa frumentacea</i> Species of grass

Echinochloa frumentacea is a species of Echinochloa. Both Echinochloa frumentacea and E. esculenta are called Japanese millet. This millet is widely grown as a cereal in India, Pakistan, and Nepal. Its wild ancestor is the tropical grass Echinochloa colona, but the exact date or region of domestication is uncertain. It is cultivated on marginal lands where rice and other crops will not grow well. The grains are cooked in water, like rice, or boiled with milk and sugar. Sometimes it is fermented to make beer. While also being part of staple diet for some communities in India, these seeds are, in particular, eaten during religious fasting. For this reason, these seeds are commonly also referred to as "vrat ke chawal" in Hindi. Other common names to identify these seeds include oodalu (ಊದಲು) in Kannada, Shyamak (শ্যামাক) or Shyama Chal in Bangla, jhangora in the Garhwal Hills, bhagar (भगर) in Marathi-speaking areas, samo or morio seeds in Gujarati, or kuthiraivaali (குதிரைவாளி) in Tamil.

<i>Echinochloa esculenta</i> Species of plant in the family Poaceae

Echinochloa esculenta is a species of grass in the family Poaceae. It is referred to by the common names Japanese barnyard millet or Japanese millet, is a species of Echinochloa that is cultivated on a small scale in India, Japan, China and Korea, both as a food and for animal fodder. It is grown in areas where the land is unsuitable or the climate too cool for paddy rice cultivation. However, the development of rice varieties that can withstand cold has led to a sharp decline in the cultivation of Japanese barnyard millet, in favor of rice. The earliest records of the domesticated form date to 2000 BC from the Jōmon period of Japan.

<span class="mw-page-title-main">Echinochloa colona</span> Species of plant

Echinochloa colonum, commonly known as jungle / wild rice, deccan grass, jharua or awnless barnyard grass, is a type of wild grass originating from tropical Asia. It was formerly classified as a species of Panicum. It is the wild ancestor of the cultivated cereal crop Echinochloa frumentacea, sawa millet. Some taxonomists treat the two taxa as one species, in which case the domesticated forms may also be referred to as E. colonum.

<i>Echinochloa crus-galli</i> Species of plant

Echinochloa crus-galli is a type of wild grass originating from tropical Asia that was formerly classified as a type of panicum grass. It is commonly known as cockspur, barnyard millet, Japanese millet, water grass, common barnyard grass, or simply "barnyard grass". This plant can grow to 60" in height and has long, flat leaves which are often purplish at the base. Most stems are upright, but some will spread out over the ground. Stems are flattened at the base. The seed heads are a distinctive feature, often purplish, with large millet-like seeds in crowded spikelets.

<i>Echinochloa stagnina</i> Species of plant

Echinochloa stagnina is a species of Echinochloa widespread in tropical Africa and Asia, with an invasive status in many Pacific islands. It was once one of the major grasses cultivated in the Inner Niger Delta of the Niger River. It was cultivated by the Fulani people, who used the seeds as food, and to make both alcoholic and nonalcoholic beverages.

<i>Setaria</i> Genus of grasses

Setaria is a widespread genus of plants in the grass family. The name is derived from the Latin word seta, meaning "bristle" or "hair", which refers to the bristly spikelets.

<i>Panicum antidotale</i> Species of grass

Panicum antidotale Retz. is a tall, coarse, woody perennial grass throughout the Himalaya and the Upper Gangetic Plain and specifically in various regions of the Indian state of Punjab and the Pakistan province of Punjab and the neighbouring areas of these regions. The plant has strong spreading rhizomes.

<i>Brachiaria</i> Genus of grasses

Brachiaria, or signalgrass, is a genus of plants in the grass family native to tropical and subtropical regions of Asia, Africa, Australia, southern Europe, the Americas, and various islands. There are over 100 species.

<i>Urochloa</i> Genus of grasses

Urochloa is a genus of plants in the grass family, native to Eurasia, Africa, Australia, Mexico, and the Pacific Islands. Common names include signalgrass.

<span class="mw-page-title-main">Paniceae</span> Tribe of grasses

Paniceae is a large tribe of the subfamily Panicoideae in the grasses (Poaceae), the only in the monotypic supertribe Panicodae. It includes roughly 1,500 species in 84 genera, primarily found in tropical and subtropical regions of the world. Paniceae includes species using either of the C4 and C3 photosynthetic pathways, as well as presumably intermediate species. Most of the millets are members of tribe Paniceae.

<i>Atherigona</i> Genus of flies

Atherigona is a genus of flies in the family Muscidae.

Brachiaria deflexa is an annual millet grass belonging to the grass family (Poaceae). It is native to many regions such as Africa, India, and Pakistan in both tropical and subtropical regions. It has been used as a supplemental food source among other cereal crops.
