Control de la mancha azul en madera de Pinus caribaea var. hondurensis Barr. et Golf. en Turrialba, Costa Rica

Abstract

This paper was designed to study the control of blue stain in Pinus caribaea var. hondurensis at Turrialba, Costa Rica. The mixture of pentaclorophenol and diesel was not effective to avoid neither control blue stain in logs stacked 4.5 to 90 days in the woods. Sodium pentaclorophenate was proved effective to prevent and control blue stain in sawn lumber during an observation period of 52 days. This lumber reached the saturation point of the fiber in 38 darays of air drying under a roof.
