Abstract:
Weeds compete with tea, reducing the yield. They also interrupt field operations. Managing weeds in tea
plantations has become a crucial issue due to high cost of labour and other inputs such as herbicides,
especially at a time the end product fetches a lower NSA. Thus, a low cost weed management strategy is of
paramount importance for the sustainable productivity of tea plantations. Adoption of cultural, and
ecological methods is of great importance as they are environmental friendly and cost effective. They are
land preparation, proper bush management, infilling, mulching, establishment of cover crops and green
manure crops and leaving desirable weeds on ground. However, use of various herbicides has proven to be
the most convenient and effective method and it could minimize soil erosion and eliminate loss of plant
nutrients. Various herbicides have so far been recommended by the TRI for weed control in tea fields. There
are number of problem weeds in tea fields at present as they are resistant to normal dosage of recommended
herbicides. As such, these weeds have to be managed using specific herbicide dosages or cocktail mixtures or
by adopting other control measures. For cost effective weed management strategies ensuring healthy
growth of tea and good quality of made tea, safe and effective use of herbicides have been emphasized. The
decision making on the adoption of aforesaid integrated weed management techniques more rational way
would only be the solution for more cost-effective weed management and for healthy tea production.
