Effect of the Storage Time of Logs in Anti-Stain Treatment Effectiveness

M A Peredo, C Barria

Storage of green lumber, for 7 months, operationally treated with anti-stain products, depending on the storage time of the logs (10, 20 and 30 days) post harvesting allows to affirm that with increasing storage time of the logs, occurs a progressive increase in intensity, severity and types of fungi present in the logs. It is further noted, a significant increase in the percentage of sawn lumber affected by fungi the longer the logs remain in storage, which results in a decrease in the effectiveness of the anti-stain treatment applied. The study results allow the conclusion that in order to reach an effectiveness of the anti-stain treatment equal or higher than 95%, it is required to process the logs with a maximum of 10 days post harvesting, if the procedure of re-sawing of matrix is used with three days of storing after the sawing and logs with a maximum time of storage of 20 days post-harvest, if the timber is subjected to re-sawing immediately.
