Verticillium Wilt
Verticillium Wilt
List of files and visuals associated with this text.
Cause: Verticillium is a soil fungus that infects the roots of a tree or shrub but does not cause a rot. The fungus grows into the water- and food-conducting tissues that feed a section of the plant. Thus, Verticillium wilt often will occur on just one half or one section of a tree, the section fed by the infected root. Plants may be infected when bought from a nursery but show no symptoms. The stress of transplanting then can cause collapse.
Control: Burn infected wood of dead plants -- do not chip and use for compost, or bury. Revitalize the root system as described under General decline and dieback.
