A comparative study has been carried out between dipping and boucherie method for three major bamboo species namely borak (Bambusa balcooa Roxb.), talla (Bambusa tulda Roxb.) and jawa (Bambusa salarkhanii Alam) with CCB (Chromated-copper-boron). Preservative treatment has been carried out with five different concentrations of preservative (2%, 3%, 4%, 5% and 6%) and four different durations of dipping (2 days, 4 days, 6 days and 8 days). It has been observed that jawa (Bambusa salarkhanii Alam) and bamboo can be treated more easily and effectively than borak (Bambusa balcooa Roxb.) and talla (Bambusa tulda Roxb.). In boucherie method, 2% concentration has been given adequate penetration of preservatives. Similarly, 6% concentrations and 8 days duration of dipping has been given better results of preservative penetration. Boron has been penetrated better than copper for all variables. Boucherie method is better than dipping method because this method can preserve a full length of green bamboo within a very short period of time.
