Summary of Invasiveness
Top of pageD. annulatum is a perennial grass widely naturalized in tropical and subtropical regions of the world where it has been intentionally introduced. This grass species is used for grazing and for hay and silage (Barkworth et al., 2003; Cook et al., 2005; FAO, 2014). It has escaped from cultivation and has become a weed in the United States, Australia, Mexico, Central America and the West Indies (Villaseñor and Espinosa-García, 2004; Chacon and Saborío, 2012; Gonzalez-Torres et al., 2012; Randall, 2012; USDA-NRCS, 2014). D. annulatum has been intentionally introduced as a pasture grass because of its capability to establish on a wide variety of soils (including poorly drained soils), and its salinity and drought tolerance (i.e., 6- 8 months dry seasons; Cook et al., 2005). It competes aggressively with other plants and grows forming dense stands (Vibrans, 2011). D. annulatum also tolerates seasonal burning (Cook et al., 2005).

Notes on Taxonomy and Nomenclature
Top of pageThe genus Dichanthium of the family Poaceae comprises 20 species native to the Old World, but hybrids between different species have been reported (Saxena and Chandra, 2006). The name Dichanthium comes from the Greek “dicha” = in two, as in two separate things, and “anthos” = flower, as a reference to the presence of homogamous and heterogamous spikelets (Barkworth et al., 2003). The species D. annulatum is highly apomictic and it can form hybrids with other species such as D. fecundum (Saxena and Chandra, 2006). Thus, a considerable morphological variation has been reported for this species (Agarwal et al., 1999).
Description
Top of pageD. annulatum is a perennial grass with culms 25-100 cm tall, ascending, nodes pubescent. Sheaths lax, terete, 3-4 cm long, glabrous except finely pubescent on margins near throat; ligule a shallow membrane, approximately 1.5 mm long; blades linear-acuminate, 3-30 cm long, 2-7 mm wide, margins sparsely pubescent, apex attenuate, base subcordate. Inflorescences composed of (1) 2-15 subdigitate, short-pedunculate racemes, each raceme 3-7 cm long, peduncles glabrous; spikelet pairs subimbricate along a slender filiform axis, with 0-6 smaller homogamous spikelet pairs at base, the joints and pedicels flattened, margins setose; sessile spikelet narrowly oblong, 2-6 mm long, first glume cartilaginous, slightly concave, villous below the middle, pubescent with long bulbous-based hairs above the middle, obscurely nerved, margins inflexed, apex obtuse to subacute, second glume narrowly boat-shaped, 2-6 mm long, 3-nerved, scabrid on back of the midnerve toward apex, obscurely scaberulous over the back toward apex, hyaline, first lemma delicately hyaline, oblong-rounded, setose near tip, approximately 2 mm long, palea absent, second lemma linear, approximately 1.6 mm long, hyaline, with the central nerve excurrent as a geniculate, twisted awn 8-25 mm long; pedicellate spikelet with first glume narrowly ovate-truncate, approximately 3 mm long, 11-nerved, pectinate-setose along the back of the inflexed margins, midnerve setose on the back toward apex. Caryopsis oblong to obovate, dorsally compressed, approximately 2 mm long (Wagner et al., 1999).
Distribution
Top of pageD. annulatum is native to Africa, tropical and temperate Asia, the Middle East, and Papua New Guinea (Clayton et al., 2014; USDA-ARS, 2014). Currently this species is widely naturalized in Australia, America, and islands in the Pacific Ocean (see distribution table for details; Randall, 2012; Clayton et al., 2014; PIER, 2014; USDA-ARS, 2014).

History of Introduction and Spread
Top of pageThe date of the initial introduction of D. annulatum into new habitats is uncertain, but most likely it occurred during the late nineteenth or early twentieth century. For the West Indies, this species was first reported in 1915 in Cuba and in 1922 in Puerto Rico (US National Herbarium Collection). Between 1944 and 1954, the species D. annulatum and several cultivars were intentionally released in Texas, USA (Cook et al., 2005).
Risk of Introduction
Top of pageThe risk of introduction of D. annulatum is very high. This grass has been repeatedly intentionally introduced in tropical and subtropical regions to be used as a fodder, forage, hay, and silage crop (Cook et al., 2005; FAO, 2014). It has escaped from cultivation and rapidly naturalized into natural areas where it colonizes new areas forming dense stands and displacing native vegetation. It is apomictic and produces large numbers of wind-dispersed seeds (Vibrans, 2011). In addition, D. annulatum is fire and drought tolerant, which are features helping this species to outcompete native species (Cook et al., 2005; Queensland Department of Primary Industries and Fisheries, 2011).
Habitat
Top of pageD. annulatum can be found growing in waste and disturbed sites, urban areas, dry coastal sites, arid wetlands, sand dune grasslands, and along roadsides near pastures and grazing areas where this species often escapes and become weedy (Wagner et al., 1999; Cook et al., 2005; Queensland Department of Primary Industries and Fisheries, 2011). It is adapted to grow in conditions ranging from moist tropical and subtropical regions to dry and arid habitats (Barkworth et al., 2003; Cook et al., 2005).

Hosts/Species Affected
Top of pageIn Australia, D. annulatum is competing aggressively with important native grasses such as the species Eriachne benthamii. In Texas (USA), this species has escaped from pastures and is outcompeting native grasses in bluestem coastal grassland communities (Queensland Department of Primary Industries and Fisheries, 2011).

Biology and Ecology
Top of pageGenetics
The basic chromosome number in Dichanthium is 10, however the species D. annulatum shows different ploidy levels with chromosome number 2n = 2X= 20, 4X = 40 and 6X = 60 with tetraploids being the most common (Saxena and Chandra, 2006).
Reproductive Biology
D. annulatum is a highly apomictic species, but it also shows facultative apomixis and different levels of sexual reproduction. It is predominantly wind-pollinated (Ambasht and Maurya, 1970; Cook et al., 2005; Saxena and Chandra, 2006; Vibrans, 2011).
Environmental Requirements
D. annulatum grows in dry to moist environments from sea level up to 1600 m asl with mean annual rainfall ranging from 300 to 1400 mm and annual mean temperatures of 12.5 to 27.5°C (Duke, 1983; FAO, 2014). It is well-adapted to drought and can grow in areas with dry seasons lasting up to 8 months (Cook et al., 2005). D. annulatum is also adapted to a wide variety of soil types from sandy to heavy soils with neutral to alkaline conditions. It can tolerate poor drainage, salinity, and seasonal burning but not waterlogged conditions (Cook et al., 2005).

Notes on Natural Enemies
Top of pageD. annulatum is parasitized by Striga asiatica (Orobanchaceae) and several Claviceps species may generate a significant reduction in seed production. In addition, a wide number of fungal species have been reported affecting this species (Cook et al., 2005; FAO, 2014): many of these are listed in the Natural Enemies Table.
Means of Movement and Dispersal
Top of pageD. annulatum spreads mainly by seeds, but also by stolons. It produces large numbers of seeds which are mainly wind-dispersed. Seeds can also be dispersed secondarily by animals such as birds and by cattle, agricultural machinery and as a contaminant in grass seeds, agricultural products, and soil (Cook et al., 2005; FAO, 2014; Prota4U, 2013).

Environmental Impact
Top of pageD. annulatum behaves as a grass weed and competes aggressively once established, often suppressing other species and forming dense stands. It has the potential to alter ecosystem functions by altering fire regimes, hydrology cycles, nutrient cycles, and community composition because it is drought-resistant and tolerates seasonal burning and saline conditions (Cook et al., 2005; Vibrans, 2011; FAO, 2014; PIER, 2014). In Australia, this species is highly invasive in arid wetlands where it is competing aggressively with important native grasses such as the species Eriachne benthamii (Queensland Department of Primary Industries and Fisheries, 2011). In Texas (USA), this species has escaped from cultivation and is outcompeting native grasses in bluestem coastal grassland communities (Barkworth et al., 2003; Queensland Department of Primary Industries and Fisheries, 2011).

Uses
Top of pageD. annulatum is one of the most commercialized fodder grasses, especially in India and SE Asia because it is adapted to intense grazing and tolerates drought and fire (Duke, 1983). It is often planted as pasture for grazing and as a hay and silage grass. D. annulatum is also used for controlling soil erosion on sloping fields and to improve degraded grasslands (Cook et al., 2005; Prota4U, 2013).

Similarities to Other Species/Conditions
Top of pageDichanthium is closely related to Bothriochloa, but can be distinguished by its pedicels and rachis internodes being solid and lacking a median, purple line (eFloras, 2014).
Prevention and Control
Top of pageDue 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.
D. annulatum is susceptible to glyphosate (Cook et al., 2005).
