Information
Description
Verticilium wilt is caused by a soil-dwelling fungus that can cause water-transporting cells in the infected tree to shut down. This causes leaves to brown and die. Verticillium wilt usually only appears in damaged or otherwise stressed trees.
Susceptible species
Certain species of maple, ash, dogwood and linden trees to various degrees
Treatment
Plant verticillium-resistant species and keep nitrogenous fertilizers to a minimum.
