Weed management
Preparation before the training:
First, you need to understand which noxious weeds and which soft weeds exist on your farm. Following are some
examples of noxious weeds and soft weeds that are commonly found on tea farms.
Soft weeds
Ageratum
Axonopus compressus
(Flat grass)
Oxalis
Glechoma hederacea
(Ground Ivy, Creeping Charlie)
Borreria hispida
(Bagracot)
Parthenium hysterophorus
(Parthenium weed, Carrot grass)
Noxious weeds
Cyperus pilosus
Eupotarium odoratum
(Siam weed)
Digitaria sanguinalis
Ferns
Cynodon dactylon
(Dhoop grass)
Imperata cylindrica

Weed management
Preparation before the training:
Collect different kinds of weeds that exist on the farm. Make sure
to collect both noxious weeds and soft weeds.
(See the next page to understand which species are noxious weeds
and which are soft weeds.)
Training technique:
Step 1:
Ask the participants to look at the pile of mixed weeds. Ask one participant to pick one weed from the pile. Ask
him/her what is the name of the weed and whether it is a noxious weed or a soft weed.
Step 2:
If a participant can tell a correct information about a weed, applaud him/her, and ask another participant to pick up
another weed from the pile. If the participant did not know the correct information, explain the name of the weed
and whether it is noxious or not.
Step 3:
As each participant picks up the weeds one by one, put the soft weeds on one side and put the noxious weeds on the
other side.
Step 4:
Continue the exercise until all the weeds are identified and segregated to soft weeds and noxious weeds.
Step 5:
Explain to the participants that soft weeds are the ones which do not compete with tea, and need to be maintained
at lower height by sickling. Noxious weeds are the ones which compete with tea, and some of them are invasive.
They need to be manually uprooted to prevent further spread.
