Ailanthus Cure -- 001

forest with Ailanthus tree wilt

A Penn State researcher found considerable wilt and death in a tree-of-heaven grove in a southwestern Pennsylvania forest in 2003. Further research suggested that a fungus was causing the dieback. Researchers now believe that the fungus could play a key role in controlling the invasive spread of the tree-of-heaven.
