Weevil - red rot associations in eastern white pine

Informally Refereed

Abstract

The presence of red rot (Fomes pini) in pruned white pine stands has often been attributed to the act of pruning. This assumption may well be true for heavily stocked stands where thinning has been neglected and pruning scars are slow to heal. The question then arises: How do we account for the red rot often found in vigorous unpruned white pine stands? Evidence collected in connection with a white pine log-grade study at the Pack Demonstration Forest at Warrensburg, N.Y., strongly suggests that the white pine weevil was responsible for much of the red rot found in the trees examined.
