A.tumefacians is a soil-inhabiting bacterium with the broadest host range of any bacterial plant pathogen. Galls alone are not typically fatal to trees. And it seems, from this photo at least, that this growth already has spanned the diameter of the trunk. If it is crown gall. then it will not kill the tree but it will weaken it and slow it's growth rate significantly. Some galls can weaken a tree to the point taht a secondary pathogen can move in for the kill however.Forest Keeperhttp://forestkeepersofcapecod.com/blog/noreply@blogger.comtag:blogger.com,1999:blog-797638742579164297.post-38684975791142891222012-12-03T02:52:13.940-05:002012-12-03T02:52:13.940-05:00Now that's an interesting looking burl!

Ususlly caused by a wound created on the tree. The fungus enters thru the bark at wound site during the growing season and continues to grow every growing season until it girdles the tree and the tree dies. probably caused by a branch that broke off during a heavy snow/ice event.Anonymousnoreply@blogger.com
