Description

Top of page C. aciculatus is a rhizomatous or stoloniferous, spreading perennial. Culm often erect, 15-25 cm tall, geniculate, branching; always rooting at the nodes. Leaves 3-15 cm long, 2-6 mm wide (15 to 20 times as long as wide), linear, often hairy at mouth only. Ligule membranous and truncate. Inflorescence a panicle, 5-10 cm long, 2.5 cm wide, composed of several whorls of short reddish branches which gradually spread horizontally when ripe. Each branch bearing at its end a group of three spikelets. Branch axis jointed below the spikelet group. Spikelets ternate and similar: one sessile hermaphrodite aproximately 4 mm long with a hairy oblique callus; two pedicelled, male or neuter. Glumes: G1 2-4 mm long, 3- to 2-nerved; G2 2-4 mm long, 3-nerved with 1.5- to 2-mm-long awn. Lemmas: L1 2-3 mm long, hyaline; L2 hyaline, 1-nerved, awned, awn 2.5-8 mm long, straight. Caryopsis oblong, 2 mm long.

Distribution

Top of page Häfliger and Scholz (1980) list Chrysopogon aciculatus as being present in Central and Western Africa, the Indian subcontinent, the South-East Asian subcontinent, China, Philippines, Indonesia, Australia and the Pacific Islands. It is native to South-East Asia, Australia and Fiji (USDA-ARS, 2003) and probably native elsewhere in the Pacific and an early introduction on other islands.

Habitat

Top of page C. aciculatus is a tropical grassland species. Lehmkuhl (1992) noted that it dominated grazed pasture based on a study in lowland Nepal. It occurs throughout the Philippines in open grasslands (Pancho and Obien, 1983). It is an exotic in Nigeria where it is well established as a lawn grass (Stanfield, 1970).

Hosts/Species Affected

Top of page C. aciculatus is recorded as a weed species from tea fields in Assam, India (Barthakur et al., 1989), rubber plantations in Malaysia (Wycherley and Ahmad Azli bin Mohd, 1974) and from tobacco farms in the Philippines (Pancho and Obien, 1983).

Biology and Ecology

Top of page In a study of vegetation dynamics, Mueller-Dombois (1981) recorded C. aciculatus from tropical grasslands with mediterranean seasonal rainfall on leeward Hawaii. Wycherley and Ahmad Azli bin Mohd (1974) describe it as prefering rather dry, open conditions although it can also persist in turf for a long time. It proliferates under heavy grazing regimes (Robertson and Humphrys, 1976; Partridge, 1986). Grasslands in Kalimantan, Indonesia, probably originated through shifting cultivation of forest land and subsequent burning. Cattle grazing on these grasslands resulted in the replacement of Imperata cylindrica by Axonopus compressus and C. aciculatus if sufficiently intensive (Seavoy, 1975).

Uses

Top of page C. aciculatus has been used for erosion control, lawns, forage and medicines (USDA-ARS, 2003).

Prevention and Control

Top of page

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.

Cultural Control

Mueller-Dumbois (1981) noted the reduction in this species during a study in Hawaii where the grassland was protected from grazing goats.
