>Enclosed are a couple articles that describe how the red stain is created.
Excerpt "The red stain is most likely produced by the tree as a nonspecific host response to wounding".
Excerpt "It has been reported that the stain is caused by the infection of the fungus Fusarium reticulatum. A recent study, however, gives evidence that the cause of this staining may be related to nonspecific causes, particularly wounding caused by environmental factors, insect injury, or sapsucker injury."
If anyone has a better article explaining the red staining process, please attach to this thread.
