BIOLOGICAL CONTROL OF KILN BROWN STAIN IN RADIATA PINE

Kiln brown stain in radiata pine (Pinus radiata) is a chocolate-brown discolouration that forms near the surface of boards dried at high temperature. This stain is the result of a thermochemical reaction between compounds in the sap that accumulate at the surface of the boards during drying. In this...
