Tea is under cultivation in Darjeeling hills since 1835 and in Terai it was introduced in 1862. Any cultivated field in this region is liable to be affected by weed infestation as the local flora is extremely rich. The crop loss in tea gardens of this area is quite considerable and the planters practice a good variety of deweeding techniques. Four tea gardens of Terai, namely (1) Hansqua, (2) Kamalpur, (3) Satvaya and (4) Gulma and morhorgong Tea Estates were surveyed for flora and phytosociological information. While the existence of a rich and diverse flora has been exposed, the similarity of the weed flora of these gardens is quite high and four weedy species have been recognised which are affecting all these gardens almost uniformly.
