Environmentally and economically very important mulibamboo (Melocanna baccifera) grown in Bangladesh was fond to be easily pressure treatable with CCA-C at green and air dry conditions. The green and air-dried bamboo treated at same treating conditions and concentration showed 110 per cent (2.10-times) higher retention in air-dried bamboo than green one. Adequate lower retention equivalent to 6.40 kg/m3 (1.25 per cent w/w) dry oxides of CCA-C for indoor and outdoor overhead uses, can be obtained by full-cell pressure treating round green bamboo with 4 per cent CCA-C solution or sliced air-dried bamboo with 2 per cent CCA-C solution. Adequate higher retention equivalent to 20 kg/m3 (4 per cent w/w) for ground and water contact uses can be obtained by treating airdried (15 per cent MC) round bamboo with 5 per cent CCA-C solution. CCA retains more in node than internode and CCA-C fixes adequately in bamboo if dried slowly after treatment and before use. Two small holes at each internode before pressure treatment ensure treatment of split free bamboo.
