Wood can be damaged by biological agents due to its organic origin and environmental conditions. To protect the wood and increase its useful life it is necessary to submit it to preservative treatment. So, the present study aimed to evaluate the biological resistance of the treated wood of Eucalyptus grandis and Eucalyptus cloeziana under the action of biological organisms in field trials. We used trees of E. grandis and E. cloeziana, with 16 years old, which were split into planks and submitted to drying outdoors to later make up the preservative treatment in an autoclave with chromated copper arsenate (CCA). The samples were prepared to conduct the test field. It was observed that the preservative treatment was effective in reducing the biological degradation of wood from both species. Comparing the results obtained for the two species, it was observed that E. cloeziana presents greater ability to be used in adverse conditions or in contact with the ground.Downloads
