Resumo: | The Rhizoctonia is a stainer fungus that causes great damage to the timber industry, attacking several species of commercial interest. The objective of this study was to evaluate the resistance of wood sawn Jatoba with different moisture contents to the fungus Rhizoctonia solani attack, in a controlled environment and natural conditions. The experimental design was completely randomized with factorial arrangement of 2 x 2 x 4 and 12 repetitions. The treatments consisted of two regions of the wood sample collection (sapwood and heartwood), two environments B.O.D. (± 24 °C) under natural conditions (± 30 °C) and four levels of moisture (control, 20%, 40-45% and 70-75%). For the determination of the fungal mycelium, was used with plastic template size 0.05 x 0.05 meters, consisting of 100 squares where each is only 1% of the test body. The results showed favor the development of the fungus in the sapwood samples with moisture content in the range of 70-75% in a controlled environment, being more intense than at 20 and 40-45%, characterizing that Rhizoctonia grows best under high content humidity. the importance of holding the timber drying process, thus obtaining moisture content detrimental to the development and fungal attack is evident.
