Eragrostis ciliaris is distributed in tropical, subtropical and temperate regions of both the Old and New World Stone, In its native range it has a paleotropical distribution in the tropical and subtropical regions of Africa, through the Indian Ocean and Arabia to Pakistan, India, Sri Lanka, Myanmar, Vietnam and the Philippines Clayton et al.
The distribution in this summary table is based on all the information available. When several references are cited, they may give conflicting information on the status. Further details may be available for individual references in the Distribution Table Details section which can be selected by going to Generate Report. Eragrostis ciliaris has been introduced outside its native range in tropical, subtropical and temperate areas in America and Oceania, and is probably a recent introduction in Taiwan Flora of Taiwan Editorial Committee, The risk of further introductions of Eragrostis ciliaris is moderate to high, given its likely unintentional introduction outside its natural range by seed contamination via traded grain commodities.
In view of its current distribution, the introduction of the species in new countries in tropical regions is highly likely. It is a common weed of disturbed ground, and roadsides. Reproduction and propagation are mainly by seeds PlantNet, Physiology and Phenology. In Pakistan E. Environmental Requirements. Eragrostis ciliaris develops mainly in light, sandy soils Burkill, ; Flora Zambesiaca, It also grows on stony and dry ferralitic soils.
It is rare in very clayey and humid soils such as vertisols or planosoles. PlantNet, In Puerto Rico, it occurs between and m elevation Gann and Stocking, , and in Africa, from sea level to m.
Clayton et al. It can tolerate long droughts Quattrocchi, The nematode Meloidogyne incognita has been reported as a parasite of E. Eragrostis ciliaris spreads by seeds Burkill, ; PIER, which may be dispersed by wind, water and birds.
Accidental Introduction. Eragrostis ciliaris is included in the list of weeds affecting rice crops throughout the world PlantNet, Therefore, it is likely to have been introduced unintentionally by seed contamination through traded grain crops. Eragrostis ciliaris is used as a forage grass and, in sufficient quantity, provides good grazing Quattrocchi, ; Flora of Pakistan, ; CICY, Social Benefit.
Eragrostis ciliaris is used for stabilizing coastal sand dunes Burkill, The longer culms may be bundled for sale as brooms or used as thatch Quattrocchi, The plant is sometimes harvested from the wild and consumed as a cereal Burkill, It is also used medicinally, to treat stomach pains Burkill, Eragrostis ciliaris can be distinguished from other Eragrostis species by its palea hairs 0.
Due to the variable regulations around de registration of pesticides, your national list of registered pesticides or relevant authority should be consulted to determine which products are legally allowed for use in your country when considering chemical control. Pesticides should always be used in a lawful manner, consistent with the product's label.
Post-emergence herbicides such as 2 4-D or the pre-emergence herbicides, butachlor, anilophos and pretilachlor, can control this species effectively. Alternatively, control of this species has been observed in cluster bean crops in arid regions, following use of a combination of irrigation with mustard oil-cake and mustard pod straw Saxena and Lodha, Allarangaye, M.
