Weeds do enormous damage to the tea crop. They directly deplete the soil nutrients and moisture and compete with crop plants for light and space thus, reduce the crop yields. Indirectly, they cause damage to the crops harbouring pests and disease agents.

Weeds in Tea Like other agricultural and horticultural crops, tea also needs optimum agronomic care for a high and sustained productivity. Among the critical factors limiting optimum productivity from tea plantations, weeds are counted as one in the top of the list.

Digitaria sanguinalis is an annual grass (living for 1 season only) with long (up to 1m) sprawling stems. As with all grasses it has ďŹ brous roots. The many soft stems grow close to the ground in an open space or will push up through other grasses when crowded. The stems when they are close to the ground will often produce roots at the nodes (elbows along the stems). Stems are variable in colour from green to purple, as are the ligules. Ligules are the small appendage seen at the base of the leaf when the leaf is pulled back from the stem. The ligule on this grass is a membrane 1-2mm long.

Cynodon Dactylon It is also known as Bermuda Grass, Dubar and Doob. The blades are a grey-green colour and are short, usually 4-15 cm long with rough edges. The erect stems can grow 1-30 cm, rarely to 3 ft, tall. The stems are slightly flattened, often tinged purple in color. The seed heads are produced in a cluster of 3–7 spikes (rarely two) together at the top of the stem, each spike 3–6 cm long. It has a deep root system. In drought situations with penetrable soil, the root system can grow to over 2 m deep, though most of the root mass is less than 60 cm under the surface. The grass creeps along the ground and root wherever a node touches the ground, forming a dense mat. Bermuda Grass reproduces through seeds, through runners and rhizomes.
