Bamboos of different sizes are generally used for fencing, poles and sticks in betel leaf farms. Bamboo
sticks are used as climber for betel leaf vine. These bamboo materials have 2-3 years service life because these
are being used without having any preservative treatment. After treatment, the service life of these materials
can be increased by four to five times. These treated materials are not required to change or to repair every
year. A study has been undertaken to disseminate the preservative treatment technology among the common
people through the distribution of treated bamboo sticks in the betel leaf farmers. The objectives of the study
were to determine the service life of bamboo sticks used in the betel leaf farms and to motivate people for
using the treatment technology. In this regard, the bamboo sticks namely baijja (Bambusa vulgaris) and
mitinga (Bambusa tulda) bamboo were treated by soaking methods using water borne preservatives, copper
sulphate, sodium dichromate and boric acid (CCB). The treated materials were distributed to the betel leaf
farmers in three different areas of Bangladesh. Data were collected at the interval of every six months to
determine the durability of the bamboo sticks. It was found that after four years the treated materials were in
sound condition. It was observed that the preservative technology would enhance the service life of the
bamboo, which will help people to save their hardly earned incomes and conserve forest resources.
