Unfortunately, there are no treatment options. There are many other species of trees which are susceptible; a resistant species mix will be selected for replacements. Over time, more of these trees will be lost because of this disease. It is spread through the contact of root systems, by pruning tools, and even by using tools in the soil of the infected area. Tools should be disinfected with a bleach, alcohol, or Lysol product. The Coeur d’Alene Place Homeowners Association has been contacted, as members have many susceptible species in the area. Other cases of verticillium wilt have been confirmed around the city as well. Disinfecting tools is key. For more information, please contact Katie Kosanke at 415-0415.

The Urban Forestry Committee recently confirmed, through the assistance of the Forest Service lab, that the sugar maple trees on the perimeter of Bluegrass Park are declining because of the disease verticillium wilt. Verticillium wilt is a soil-borne fungus with infection occurring through the root system. Once the organism enters plant tissues, the fungus produces toxins and invades the water-conducting tissues and kills cells. Several branches first die back, with the rest of the tree following.
