Root Decay in Urban Trees - Part 2: Ganoderma sessile - An Important Root tl:Disease and Butt Decay by Any Name

摘要

You may not recognize thename, just don't forget the face(Photograph 1). The name has changed, but the widespread occurrence east of the Rocky Mountains and damage caused by this pathogen remains the same. Ganoderma sessile (formerly one of many species labeled under the name 'Ganoderma lucidum') is a common root and butt decay pathogen in urban trees. It's one of the "Big Three" that we recommend arborists become familiar with because it has a wide host range, it is relatively easy to identify in the field and it can be important to a tree's biological health and mechanical stability (Photograph 2).
