Cymbopogon citratus popularly known as lemon grass is an aromatic plant belonging to the family Gramineae and the genus
Cymbopogon [14]. It is a perennial grass growing to a height of about
1 m. The leaf-blade is linear, tapered at both ends and can grow to a
length of 50 cm and width of 1.5 cm [15]. The leaf-sheath is tubular
in shape and acts as a pseudo stem. It is native of the warm
temperate and tropical regions of the old world. Lemon grass can
tolerate a wide range of soils and climatic conditions but grows
more vigorously on fertile well drained sandy loam soil [15].
