This work aimed to evaluate the economical viability of preservative treatment of Prosopis juliflora (Sw) D.C. roundpieces treated with Osmose CCB commercial preservative applied by sap displacement method in rural property and to comparetheir costs with Mimosa caesalpiniifolia, Mimosa tenuiflora and Prosopis juliflora non-treated pieces costs. The treatment of Prosopisjuliflora wood demonstrated to be economically viable when compared to alternatives using the Equivalent Annual Costs (EACs), fordiscount rates of 12; 15; and 18% and expected useful life varying from 16 to 30 years, in these situations treated Prosopis juliflorawood presented smaller EAC than Mimosa caesalpiniifolia, Mimosa tenuiflora and Prosopis juliflora non-treated woods for theanalyzed situations, that justifies the employment of the Prosopis juliflora treated logs as fence posts and other similar uses.
