Effectiveness in bamboo preservation of wood preservation PBB and CMM.<\/b><\/p>\n

After exploitation bamboo culms are easily attacked by insects and fungi. Wood preservatives PBB and CMM were tested for their effectiveness in bamboo preservation against fungi and termites with treatment process developed by the Division for forest products preservation. Results of the test allow determination rate of each preservative in respective treatment method to ensure effectiveness in bamboo preservation.<\/p>\n","protected":false},"excerpt":{"rendered":"
