Informações adicionais: The study aimed to investigate the effect of different preservatives products and retentions on the resistance of Pinus taeda plywood to attack by decay fungi. The experiment consisted of six treatments, two types of products preservatives (CCA and CCB), two retentions (4.0 and 6.5 kg / m³), one treatment with water only, which aimed to evaluate the effect only the process of preservatives application, and a control (no treatment). The plywood was produced with Pinus taeda wood, five veneers of 3 mm thickness and phenol-formaldehyde adhesive at a weight of 420 g / m² (double line). To evaluate the resistance to biodegradation of plywood was used the methodology proposed by ASTM D2017 (2005), and evaluated the fungi Trametes versicolor and Gloeophyllum trabeum. In the resistance evaluation of the panels biodeterioration to attack the fungus Trametes versicolor was no significant effect of product type and retention. The resistance evaluation to attack by fungus Gloeophyllum trabeum, CCA applied in retention of 4.0 kg/cm ³ provided greater resistance to biodeterioration than CCB in the same retention, and in the evaluation of two retentions of CCB there was observed that retention increase to 6.5 kg / m³ resulted in significant improvement in the panels resistance to biodegradation.
