Resistance by lodgepole pine to invasion by blue stain fungi is effected by an initial flow of oleoresin followed by a gradual impregnation with resinous substances of the tissues adjacent to the wound. The addition of such resinous sapwood to growth media caused inhibition of growth whereas non-resinous sapwood enhanced growth; however, extracts from both resinous and nonresinous sapwood caused inhibition of blue stain fungi. Volatile components in the extracts were responsible for this inhibition.
